Enron engaged in practices that apparently many Fortune 500 companies had been engaging in and it came back and bite them and a certain percentage of the other companies. Some of their practices were illegal; the practice being discussed here is not. Epson has exhibited similar attitudes and practices and has faced serveral consumer revolts by some of their heavy users as well as a lose in credibility with respect to their claims and literature. I suspect the additional money they made as a result of such attitudes and practices far outweighed any consumer backlash.

You are actually required to use a lot of products with similar practices every day, you just aren't aware of it. Have you checked the margins on Motorola and Intel microprocessors lately? Do you think the telephone company is charging for calls at cost? _Everybody_ does this. Sure, but the jump from 32 to 64 bits address space gives us a hell lot more time than the jump from 16 to 32 or 8 to 16. It doesn't matter; it will be used up just as quickly. The mistake engineers make is in believing that address spaces will be allocated sequentially starting with byte zero and ending with byte 2^N-1. But that's not how it actually works. Engineers tend to assume that a given address space has more space than anyone will ever need and allocate the space in extremely wasteful but easy-to-code ways that cause it to be exhausted with alarming speed. This is why the 32-bit IP address space is in such dire straits, even though there are nowhere near 4 billion computers on the Net yet. It is also why IPv6 and IPv8 will suffer the same fate. It is also why 32-bit computers are reaching their limits even for mundane, everyday use. Years ago I was already seeing systems exhaust 36-bit addressing spaces; that's 64 billion bytes, easily a thousand times more than the physical memory capacities available at the time. Having 36 bits didn't do any good; incompetent design and coding managed to exhaust address spaces of any size in short order, no matter how large they were initially. Also, 64 bits take us to the physical limits of semiconductors ... How? ... so you may be right that we will eventually need 128 bits, but that is a long long time away (decades, and many generations of computers). Maybe, maybe not. There are ways in which 64 bits could be exhausted in just a few years. I've seen things like that happen before. Sure, but this is merely a software question really. Once the software is in place, it behaves like hardware. Contrary to common myth, even though software is not hardwired into a machine, it is extraordinarily difficult to change, especially when loaded into hundreds of millions of machines around the world. If this were not the case, we would have all moved to IPv6 overnight when IPv4 near exhaustion. Since modern operating systems have elaborate and flexible memory handling capabilities, and programs make no assumptions as to where in memory they are mapped, it's a matter of making modifications to the OS and BIOS to solve this problem. Not really. Individual applications must allocate virtual space in an intelligent and economical way as well, and usually they do not. The fact that more expensive versions of Windows can address 3GB per process shows this. Not relevant--these expensive versions of Windows still operate within the 32-bit restriction. The fact that special versions were required even before the 32-bit limit was reached, however, illustrates the magnitude of the problem. In the case of Windows NT and its successors, the problem is that the original engineers very wastefully declared that 2 GB of the 32-bit address space would be reserved for the OS, and 2 GB would be reserved for applications. Well, as time passed, the application space rapidly approache exhaustion, while the OS space remained largely empty. And so a lot of code had to be rewritten to reduce the OS space and expand the application space. If the original designers had demonstrated a bit more foresight, this would never have been necessary.

Roger writes: If I understood correctly the CMYK issue, it has little to do with photographers but is crucial on the printer's side. Yes. CMYK is irrelevant if you never intend to print anything on paper; it is unavoidable if you want hardcopy. There seems to be an agreement on the gamut limitation relative to RGB and that any file translation must use the specific printer profile. One reason why it is so hard to get a perfect match from inkjet printers is that they are actually printing in CMYK, even though you are trying to supply them with an RGB image. Digital photographers are now being requested to perform most pre-press work (sometimes even including blind CMYK conversion) before sending their images to the publisher. Blind CMYK is a really bad idea, since CMYK conversions must always be done with a specific output device in mind. If the real output device isn't the same, image quality is always lost, and it cannot be recovered. Some are wondering if it couldn't be more rewarding to get back to film photography, sending slides as previously and not caring about pre-press and colour management. Just provide files as RGB. Tweak them to look good on a monitor, not on paper. It's up to the end user to convert the image for printing, since every end user will have different requirements for CMYK conversion. It's illogical to expect a photographer to do this, and any customer wanting it must be pretty clueless about how CMYK works.

Andras writes: OK, what I actually meant is how many people use CMYK colour space when manipulating images in PhotoShop or so. The entire publishing world. It is a key feature of Photoshop, and a heavily used one, and one of the most important features of Photoshop to professionals (which is why it is absent in cheapo versions of PS such as Photoshop Elements). Yes, printers often have CMYK components, but that should be hidden from the user by the printer driver. Most of what is printed on paper in the world doesn't pass through a printer driver on a PC or Mac. Most of it passes through large or even huge offset or other types of printing presses, and these presses understand only CMYK. They use plates created from films that are exposed by raster-image processors that understand only CMYK as well. Outside the tiny world of the PC or Mac itself, all of the printed material in the on the planet exists in a CMYK universe. For manipulating and storing images, the fourth channel black is totally redundant. No, it is not. CMYK requires black because most inks on press are not pure enough to produce a true black from CMY alone. And the balance between black ink and CMY must be controlled for each set of circumstances, with parameters like GCR and UCR. Therefore images must be manipulated in CMYK in preparation for printing. Also, if CMYK is based on the printer's colour space, why CMYK and not CMYKcm or whatever extra colours there are? Uh ... because printers use only four colors in standard process color: cyan, magenta, yellow, and black. There aren't any other colors. (There are six-color processes, but that is exceptional.) There is no such thing as a standard CMYK space ... Yes, there are standard spaces: SWOP is one such space in the U.S. ... each output device has different characteristics. True, and the only way to tweak for the output device with complete accuracy is to convert to the CMYK space that it uses. RGB doesn't cut it. A CMYK image file has to be converted to the printer's CMYK space using ICC or similar transforms anyway ... No, it does not. You prepare the CMYK file in Photoshop so that it already conforms to the space used by the press, then you create your films and plates from that and you go to press. Nothing is transformed after you prepare the CMYK file in PS; that file IS the final image file. ... just like any RGB or other image. CMYK isn't like RGB at all. On a computer, the native colour space of the monitor is RGB, which also resembles the spectral response of the three colour receptors in the eye. Yes. But on paper, the color space is always CMYK. No printing process uses RGB, since RGB requires a light source, and doesn't work by reflection. ... it is often sufficient to work on an image in the monitor's colour space, which makes life much easier. Not for serious printing. You have to convert to CMYK if you plan to print on paper and you want good results. Any RGB format can be directly displayed on any monitor (with small deviations maybe), unlike CMYK. Fine, as long as you intend only to see it on a screen. But that won't due for printing.

Andras writes: If, as Anthony said, CMYK is useful for printing work, then it only makes sense to use CMYK if you do it in the colour space of the printer AND convert to RGB using ICC colour profiles for display on screen. If you plan to print the photographs, CMYK is useful. It can even be useful for printers driven in RGB, because the RGB gamut is larger than what any printer can put on paper, and a conversion to CMYK can show you the limits of the printed result on the screen (assuming that your CMYK conversion parameters are _exactly right_, of course). The reason you may not be getting the vivid blue or rich green that you see on the screen when you print on paper may simply be that it is outside the gamut of your printer. This is great, but it implies that the CMYK file is made for one and only one printer ... Correct. You always convert to CMYK with a specific printer and/or press and/or inks in mind. This is why you do most things in RGB (apart from the fact that RGB has greater gamut and headroom), and convert to CMYK only when you are producing an output file to go to the printer. ... so whenever a company buys a new printer that is different from the old ones in colour rendition, they have to discard (or adapt) their old CMYK files. You don't keep CMYK files, anyway. You recreate them from RGB for each use, unless you are printing under exactly the same conditions each time. Also, more and more high-quality magazines etc. use more than 4 colours, in which case the entire method becomes useless. Where did you hear that? The vast majority of magazines and all other continuous-tone printed matter is printed in four-color offset. Six-color is for special purposes and costs a lot more without necessarily adding a lot more in quality. The best four-color printing will look a lot better than average six-color printing. In any case, even if six-color printing were common, the process would still be the same. (I don't actually know if Photoshop handles six-color conversions, though, as I've never had a need to prepare them.) My suggestion here is the obvious one -- why don't we all work in CIELab or XYZ and convert to RGB for on-screen display and CMYK for printing? Mostly because of convenience. Lab is fine for representing the gamut of the real world, but no display or printing device can correctly render Lab color, so there isn't much point in working in it extensively (although Photoshop does use it internally). The same is true for spaces like Wide Gamut RGB. Until and unless someone produces monitors, printers, or some output device that can actually render the full gamut of Lab color, working in Lab color will be of limited usefulness. Thus, I think CMYK is historical dead weight which has been obsolete at least since the ICC standard was created. You're in for some unpleasant surprises the first time you become involved in actually getting a photograph from camera to press sheet. CMYK is actually more important than it has ever been in the past, since so much more is in color these days. Even the cheapest newspapers are four-color jobs today.

I wonder why Fuji does that. Maybe I can try always facing the convex side of the film towards the anti-newton glass, if it isn't already quite flat, even though this means scanning some strips backwards. I know that some strips look fine, but others have a definite problem with rings. I assume that curvature of the film or something is getting in the way. - Original Message - From: Arthur Entlich [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, September 28, 2002 03:10 Subject: [filmscanners] Re: Avoiding Newton rings The cause of Newton Rings is when a space is created between two finely polished or glossy surfaces that is a very small space equal to or a small multiple of white light wavelengths, which then cause interference colors via the reflection between the surfaces. The best way to avoid them completely is to have the space between the two surfaces be wide enough that this phenomenon doesn't occur. One way that this has been dealt with is by using a glass which has a very fine etched surface which creates very small contact points between the two surfaces. Another method is to use a very fine powder (talc is sometimes used) to again create this airpace with minimal contact points. The more often the film gets very close to the glass surface, the more series of Newton rings will develop. Some people use a one-sided glass carrier to allow the film to be supported by gravity by that bottom surface, usually having the emulsion side contact that glass surface which has more texture and is less likely to cause Newton Rings. If one can figure another way to create a large enough airspace, Newton Rings can be avoided.

The 50x60 print is very nice, though. But for 20x30 prints or below, I'm not convinced that I'm getting anything better from the pro lab, so I might just go with the one-hour prints from the Frontier for that (the difference in price is 5-to-1). The deciding factor is usually the meatware - the people running the machines, and the managers who supervise them. One thing I hope to accomplish by getting scans printed directly on Frontiers or Lambdas or whatever is to minimize human intervention. If my files are clean and if the settings on the printers are consistent, I can just hand the files to the lab and tell them to print exactly what is on the files, without touching anything. That's what I did for the one-hour lab and the results were great. The pro lab fiddled with the curves a bit on the scan (a minor improvement, but nothing I could not have done myself), but otherwise printed it as-is, also with excellent results. If I had really bad scans that had to be manhandled into proper condition, the results might have been much more variable and/or worse. Apparently these labs get a lot of rotten digital files and scans (based on what they told me). How much training have they had? How well do they calibrate and maintain their processes? Do they set the right filtration for your film? Do they use an appropriate paper? How much time do they take on each order? Will they reprint if you do not like the first run? Will the second run look better? The pro lab seems to be doing things right, since I watched part of it and it looked okay. The one-hour lab is certainly more casual, but the place I prefer is staffed mostly by photo enthusiasts (like actors, photographers hardly ever manage to live off their passion), and they take reasonable care, even if they are not necessarily experts.

Speed is not an issue for me in either 35mm or MF, and I never burn through film in MF and only occasionally in 35mm, so the advantages of digital are of little significance to me, whereas the disadvantages (staggering initial cost, immediate obsolescence, the need for an expensive infrastructure, and lower image quality) are overwhelming.

Also, by leaving the dpi at 2700 or 4000 are you creating a higher quality graphic file? No. See above. The DPI setting of the file is just an information field, like your name or the name of the application or whatever else gets thrown into the file besides the image data itself (depending on the program you are using and the settings you've selected). This being so, you can set it to anything you want. Most programs that read the file ignore the DPI setting. A few programs look at the DPI setting when you select options like display at actual print size or when you try to print a file.

Not all programs do this, however, so it's quite an unpredictable way of sizing an image, which is why it is usually best to ignore DPI unless you actually intend to print the file.

Stan writes: What if the image is being prepared for a website? The procedure is the same, but the final size for the image is of course quite small compared to the original scan. I do set the JPEG compression a lot higher for Web use than for print use, as download time is important for Web images, and quality is much less of an issue. Of the three steps--resampling to get the right size and 72 dpi, converting to JPEG format and sharpening--what is the ideal order? Saving as JPEG should always be the last step. (However, my images are archived primarily as low-compression JPEGS; this isn't a problem as the vast majority of my final uses involve downsampling the image, anyway.) Conversion to 72 dpi doesn't do anything, so you can skip that. Normally I open an archived image and downsample/unsharp in steps until I reach my final size, then save that. For the Web, I crank up the compression to make the file smaller (usually no more than 6 of 10 in Photoshop 5.x for large images, where quality is presumably more important than download volume, and often 3 for small images, where the inverse is often true). Should sharpening still be the very last step? Always. Sharpening degrades the image, so you don't want to do it until you're done with everything else. And I never sharpen scanned images for archiving; if they need sharpening, I'll do that each time I open them back up for other uses. You never know when a specific use might require the image without sharpening (an image without sharpening is cleaner).

Alex writes: what would be preferred policy of image offering for the public ? I mean small GIFs as thumbnails linked to JPEGs of certain resolution of JPEG only approach ? It depends on your intended audience and the type of connections and machines you anticipate that they will have. Designing for unsophisticated Web surfers with slow connections and small monitors is different from designing for seasoned surfers with broadband connections and huge monitors. As a general rule, keep in mind that most people have 800x600 screens in 24-bit color, with dial-up connections of 40 Kbps or so. Thumbnails are fine, if they are very small (read: highly compressed) and not too numerous on a single page. I used to use them, but as the number of images increased, it started taking a long time just to download the thumbnails, so I dropped them--but much depends on your site design. As for full-sized images, something under 800x600 is probably best. You need not design for 640x480 monitors--hardly anyone still uses those. And Web-safe colors or GIFs are a waste of time today--full-color 24-bit JPEGs are fine (and preferable for photos in any case), and they download faster. Also, what would be suitable JPEG resolution to be allowed for image download from web site achieving two goals: good on-screen image quality, optimal size and resolution for fast download and not suitable value usage ... Probably between 640x480 and 780x580 or so. Most monitors are set to 800x600 today; quite a few are set to 1024x768 as well. 700x500 is a nice size that still doesn't allow much in the way of printing on paper (although it can be stolen for other Web use). Using a lot of compression degrades images enough to make them difficult to print, too, although it also influences display quality--high compression speeds downloads, too. I thought about something like VGA size (640x480) or probably SVGA (800x600), what about resolution ? Yes, those work. If by resolution you mean DPI, you can forget about that--DPI is meaningless for Web display. If you really do wish to set a DPI, though, set it to 2700 or 4000; if anyone downloads the image as-is and tries to print it in a word-processing program (a common way of using stolen images), the high DPI will cause it to reproduce at a very tiny size, and many people stealing images in this way will not be able to figure out how to fix that, thereby preventing them from using the stolen image.

I find that the first sharpening, that applied to the image from the scanner, needs much larger strength and radius values than the second and later sharpenings. Do you turn on sharpening in the scanner? No, I don't. You never know when you'll need an image _without_ sharpening (remember, sharpening degrades image quality). I don't see much change in the initial sharpening, either, unless it's a really good scan (read: a scan of an image shot on a tripod, on slow film, that really does show detail in individual pixels). Subsequent 2x downsamples always show visible improvement when sharpened, though. I haven't tried that yet, since my experience with in-camera sharpening (consumer dcams) is that it has too low threshold setting and aggravates noise something fierce, but maybe scanner sharpening isn't so obnoxious...) I don't like to sharpen images even before I get them into Photoshop. I prefer that the raw image be free of sharpening, so that I get as much quality as possible in that raw image.

Your hypothetical of entering 11 inches in the new dimension, with the resampling box checked or unchecked, would not result in PS computing 11 inches x 4000 ppi. PS would reduce the ppi proportionately in either case. Try it. If you simply enter a new dimension in inches, the size in pixels will increase or decrease as required to produce that dimension ... at 4000 ppi.

Brian writes: If I scan a 35 mm slide or negative at 4000 dpi in a Nikon Coolscan 4000 and I want to make a print in Photoshop, I alter the long dimension to 11 inches (the short dimension ends up at whatever to retain the proper dimensions). Since this usually ends up in a file size that is smaller than what it was originally, does this mean the image will be downsampled? No. By default, when you enter a dimension in the Image Size dialog box, Photoshop will resample the image to match the dimensions you've given. In the case of pixels, PS simply resamples up or down to match the new pixel dimensions. In the case of a physical dimension like 11 inches (entered in the Print Size portion of the dialog), however, PS resamples up or down to match the new physical dimension _after_ calculating the number of pixels required by multiplying the physical dimension by the number of pixels per inch. When you open a scan from the Coolscan, the ppi is set to 4000 (the scanner's resolution); and the number of pixels in the image corresponds to the number of pixels in a 35mm frame scanned at 4000 ppi, or about 5669x3779 pixels. If you now enter just 11 inches as the new dimension in the resizing dialog, Photoshop will compute 11 inches x 4000 ppi = 44000 pixels, and will upsample the image to this size. In general, this is not what you want. You should _first_ uncheck the Resample box in the dialog, then enter the new ppi you want for your print size, then recheck the box and enter the print size you want. For example, you could first change the ppi to 300 (if that's what you want on the final print), then enter the desired print size. With a ppi of 300 and a print size of 11 inches, PS will _downsample_ from the size of the 4000 ppi scan (because fewer pixels are required). If the answer is yes then how do I downsample in powers of 2? Change pixels to percent in the upper portion of the Image Size dialog box and enter 50 (percent). ... do I go 4000 to 2000 to 1000 to 500 to 360, sharpening at each step as you suggest? That's what I do (except I'd skip it on the last downsample, because the step from 500 to 360 is too small and sharpening at that point might look too messy--sometimes I try it both ways on the last step and pick what looks best). In theory you can also downsample in one step and unsharp mask once, but then you must calculate the proper radius based on the number of pixels lost and unsharp mask up front. For example, if you downsample in one step of 500%, you'd use a radius of 4.9 pixels or so. I don't do it this way so I'm not sure how it turns out (it's easier to unsharp mask in steps afterwards, and look at the partial results after each step), but you can always try it.

To the user, this appears to change the behavior of the hardware; but it's actually a software change (in software that is rarely changed). Thus, part of the behavior of a scanner's hardware when it is addressed by a scanning program such as VueScan or NikonView is actually determined by firmware in the scanner itself.

Robert writes: Excuse my ignorance but what is the logic doing it this way instead of resample it directly to the resolution you want? It seems to give a better final result, as opposed to one single large downsampling step, although I have not been able to rigorously verify this. If you downsample from 1000 pixels to 10, for example, you get a blur, even after sharpening. If you downsample in multiple steps of no more than 1/2 at a time, the result at the end seems a lot more recognizable. I think this is because steps larger than 1/2 tend to lose information from intermediate pixels. If you downsample in steps and unsharp mask each time, details tend to leave traces in adjacent pixels that survive the next downsampling step. The result is a final image that contains more pixels that resemble important details of the original. It's actually probably less accurate than a single-step downsampling, but to the eye, it looks more like the original, because key details are more likely to survive (in exaggerated form, but that's what you need to make them obvious).

David writes: Just to clarify here: the sharpening with radius of 4.9 pixels or so is applied _before_ downsampling by 500%, obviously. Right? Yes, it would have to be, otherwise the information it needs would be gone. However, I haven't actually done this, so I'm not sure of the details. It seems that, from a mathematical standpoint, there should be a one-step equivalent of the multiple-step process that I use, but I've always been too lazy to try to figure it out. Additionally, I suspect that any one-step process would require some degree of calculation for each image and each downsample ratio, and I'm not really in the mood to do that each time I downsample. The multiple-step process is easier and seems to give the same results. As I understand it, there should be N + 1 sharpening operations for N downsampling opertions. The other way around: N-1 unsharp masks for N downsamples, unless the last downsample is very close to 2x itself (try it both ways and pick whichever looks better for the last step). In some sense, the first N sharpening operations have a different purpose than the last: they're to make sure the downsampling retains the detail (and contrast) you want. Yes. By unsharp masking after each downsample, you exaggerate detail. The traces of this exaggeration survive into the next step. The net result after several steps is that details that normally would have gone away in the downsampling still have left tiny traces in the final image. Technically, the image is flawed because of this, because the details are exaggerated far more than would be mathematically appropriate--but since the image is being seen by human eyes, this exaggerated detail is exactly what is needed to give an impression of greater detail and sharpness. The last sharpening is to make the final image look good. Exactly. The intermediate unsharp masks just help to carry important detail through the process; only the last unsharp mask is purely aesthetic. Or at least that is my opinion; like I said, I've not tried to come up with a mathematical proof. Try downsampling through a 100:1 ratio in steps, and then in one pass, and you'll see that doing it in steps gives you a final result that looks like a tiny, sharp version of the original, whereas a single step just produces a blur.

Paul writes: But look at most professional web sites. They're full of nested tables, not to mention frames, plus little fragments of javascript for special effects, hit counters, etc. No, they are not. Professional sites contain only the HTML required to do the job; amateur sites and wannabe sites contain a ton of code that usually only partially works and requires a great deal of time to download. In particular, sites created by amateurs and wannabes using web-design software contain an order of magnitude more code than necessary and almost never work as they should; they are a bloated, unsightly mess that can scare away at least as many visitors as it attracts. As for very high-traffic commercial sites, they usually have full-time staff to write their HTML. But they still write all or most of it by hand. You can write that stuff if you want, but I wouldn't recommend it to most people. I don't have to, and neither does anyone else. You don't need little fragments of Javascript, or special effects, or hit counters in order to make a site useful and interesting. All you need is content. The largest Web sites on the Internet are written mostly by hand in HTML. It's not difficult at all. My own site is entirely hand-written. Where did you get that idea? By looking at the code. It's also the only way to get pages to work right across a wide variety of environments and browsers. Additionally, I used to work for a company that was very well placed to know what was running on these large sites. When I do a View Source on any major web site (Microsoft, Yahoo, Amazon), it's obviously not hand-coded. Those are exactly the sites I'm talking about. Hand-written, for the most part, for the reasons stated above. It also reduces download time to write only the code necessary, not whatever junk a web-design program puts into the page. The front page of Yahoo is very carefully handwritten in order to make sure that it downloads as quickly as possible--you'll note that the site is amazingly free of special effects, animations, and the like as well. Google is the same way. But even complex sites like Microsoft's site are largely hand-written. It's easier than trying to find a web-design program that will do the same thing, and do it well, and make it small. Many of the pages are dynamically generated based on queries, cookies, etc. Using scripts that are handwritten. There are telltale signs that something was written with web-design software. Such pages are usually bloated with code and take a long time to download. They include too many special effects for their own code, with every link and graphic flashing and blinking and moving. They tend not to work on many browsers. The code itself is usually a mass of incomprehensible junk when you examine the source. It may not be done with something cheap like FrontPage, but when you see endless reams of nested tables with no indenting, you know you're dealing with HTML that was generated by software, not by hand. No, you don't. I've written stuff like that by hand. It's not hard. It may or may not be indented, depending on how it was edited. HTML generated by scripts often does not have pretty indentations; but the scripts are handwritten, too. Not erroneous links. Bad links are human error. And if you are doing something like a photo album by hand, you have to make sure that you create all the thumbnail images by hand, given them names related to the image names, and make sure that none of your HREFs are misspelled. So? It's not difficult. If you use an automatic tool, you wind up with HTML that's guaranteed to be correct. For someone with more money than time or competence, then yes, a web-design package might be a good choice, as long as the site is not too complex. For large and complex sites, or high-traffic sites, or for persons on a budget, handwritten HTML is better. Well, I don't want to get into a flame war with you. No flames intended. I just don't like to see misinformation spread around. It's easier to write your own HTML with a text editor than it is to use an expensive web-design program. HTML is easy to learn. It takes very little to build a Web site by hand, and it saves you time and money. You can learn enough to build your first Web page in about fifteen minutes. And if you ever build a really big or busy site, you'll probably end up writing it by hand, anyway, so knowing HTML always comes in handy. I do know HTML, and have created simple web sites with text editors. Then I'm surprised you'd recommend web-design junk, or compare HTML to a programming language, since it is nothing of the kind. And I think your recommendations are lousy advice for someone else who wants to create anything beyond a very basic web site with very few links, the simplest page layout, and no dynamic content. But that's EXACTLY the kind of site that will attract the most visitors. People look

It's far easier to write the HTML from scratch, and skip the web-design software. This is how most seasoned webmasters do it, anyway. It's faster and less hassle that way. I've seen C++ compilers generate hundred-kilobyte programs that I could write in a hundred bytes using assembly language. HTML is not a programming language.

And given that a 50KB page can load in 8 seconds via dialup and a fraction of a second via broadband, I'll save the much longer programming time and use Dreamweaver.

So did you actually buy the printer? - Original Message - From: Arthur Entlich [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, June 27, 2002 04:27 Subject: [filmscanners] OT: WARNING: Epson 7600/9600 ink use I just posted this to comp.periphs.printers, and I know it is off topic, BUT, since many filmscanner users might be considering the new lower priced Epson wide carriage printers, I thought I'd provide this heads up. Boy, was I excited to see the price on Epson's 24 wide printer drop by thousands of dollars with the introduction of the 7600 (list $2995 US) versus the older 7000 dye based model (list $3995) or the 7500 pigmented model (list $4995 US). Not only that, but the 7600 has a new set of even better pigmented inks available, a higher resolution inkhead, etc. and they OFFER SWITCHABLE BLACK INKS for both matte and glossy (photo) paper use with these pigmented inks! WOW, what a deal. That was until I started looking into the ink situation. The 7600 uses 110 ml ink carts (up to seven of them), and each has a lovely intelledge smart chip in it, which keeps track of all sorts of interesting stuff. Each cartridge costs $70 US or $106 CAN plus tax. The new 9600 which is a wider carriage version (44 inches wide) can use either 110 ml or 220 ml carts). Since these printers use the Intellege chip, they are not refillable, and besides, Epson owns the rights to their new ink technology. The only problem with these new inks is that the formula of the black ink makes it either work well with matte papers or glossy/photo papers, so you need two different types to provide a full range of printing abilities. BUT, no problem... you can switch between the two carts easily (it takes about 10 minutes according to Epson), One of the features of the Intellege chip technology carts is that they have a valve that shuts down the cart to keep it sealed when not in use, AND, the cartridge keeps track of exactly how much ink is in it via the chip. So, at least there are some advantages to this chip system, right? So, I take the black (glossy) cart out, buy a matte black cart (about $70 US for the 110ml version) and install it... simple, right? Well, unlike the consumer models which have the ink reservoir sitting right on top of the heads, the larger carriage printers (starting with the Epson 3000) use a series of plastic tubes to feed the ink from the ink reservoirs to the heads. Obviously, if you switch types of inks, you need to flush out the ink in the head and those tubes so the new type of ink is ready to be used. OK, so the black head is flushed so the new ink is used. It turns out that the heads also carry some ink, plus the tube, so it takes about 25-32 ml of ink to be pushed through the system to clear the old ink out and start the new ink. Well, that's a LOT of ink from a 110 ml cart, about one quarter, so you would lose about $18 US or $27 CAN (plus tax) ink for a switch one direction. Switching back to the original black would double these costs. So, you say, OK, I can swallow that, or make my client pay or whatever... not so horrible. BUT BUT, Epson didn't design the printer to work this way. OH no! Epson likes selling ink a lot, they make a lot of money selling ink, and they want to keep printer prices down, so more people buy them, so they can .. sell MORE INK! Apparently, Epson has designed their 7600 and 9600 printers to use a system similar to when the printer first is loaded with cartridges when you buy it (which uses up about 39 ml of ink per color, or about 273 ml of ink) when changing between black cartridges. Inotherwords, it not only purges the black line and head, it also purges ALL THE OTHER COLOR CARTRIDGES TOO to a total of between 180ml to 215ml of ink (according to Epson's numbers), or $114-$137 US or $173-$207 CAN (plus tax!) per switch. Or, for a full circle switch over (black to matte black to regular black again) of $228-274 US or $346-$414 CAN (plus that tax, again) just to run one print in the matte mode if you have the regular black in the printer and want to return it afterward. I do not know many clients that I can add that type of fee onto their set up costs [;-)] Now, I know that companies like Epson have shifted from larger profit margins from the printer sales, to higher profits on ink, by making 3rd party inks difficult or impossible to use with the Intellege technology, but doesn't it seem a bit self-serving to advertise these printers as providing switchable black inks as an answer to the problem of their new inks not being able to handle all substrates well, when the only way to use that feature is to waste HUNDREDS of dollars worth of ink just to switch between the black inks. I'm not an engineer, but I can't believe the cost of making the black cartridge and head assembly having its own unique purging sequence would be so great as to have made it not worthwhile to incorporate under the circumstances.

[filmscanners] Re: Scene brightness and CCDs
Todd writes: Seems to me a good S curve algorithm could juice the midtones and still keep the highlights and shadows from from blowing and blocking, no? Absolutely, and an S curve is what I had in mind (although I don't actually know for sure what sort of adjustment the cameras are performing). In order to give images more pop, the processing would logically increase the change in luminosity in the midtones, where most of the information in a properly-exposed image would be, and sacrifice detail in the highlights and shadows. A plain straight-line change would work okay, but then highlights and shadows would be abruptly cut off, and they would contain more detail than necessary for most images up to the cutoff points, to the detriment of midtones. In other words, I'd expect image-processing software to emulate the same type of curve that is built into film emulsions, with a steep midsection and a toe and shoulder at the extremes. Of course, same curve = same drawbacks, so highlights and shadows will suffer. But unless you have a magic display device that can actually display a very wide gamut and a very broad dynamic range, you have to compress something. Some digicams may be overdoing it, by forcing images into the lowest-common-denominator gamut, which would be something like sRGB. I guess this is understandable for the consumer cameras, but I should hope that the pro cameras are using something wider, or even allowing the user to select a space for rendering of an image (including raw data from the CCD, preferably, which would mean no manipulation at all). Even better would be to do this all in the analog realm, with the raw output signals from the CCD, rather than trying to adjust after conversion to digital data, because some resolution will be lost in the conversion, unless it is extremely precise internally (18-20 bits, for example). But that would be expensive, inflexible, and prone to misadjustment and environmental influences, so I doubt that it is being done. Will the RAW captures from these cameras hold detail at the extremes under conditions of large brightness ranges? How many stops of brightness for the RAW captures? I don't know. It depends what RAW means for a given model of camera. Also, even the pro cameras today are using CCDs that are too small to provide the full benefits of CCD capture. The smaller the pixel, the less charge you can hold on a given photosite, and the smaller the dynamic range of the CCD. You need big pixels to provide lots of range, and to maintain resolution, then, you also need a big CCD. This is an argument in favor of full-frame 24x36 CCDs, but nobody has them yet (practically). Another problem is thermal noise, but you'd have to actively refrigerate a CCD to really drive it down and realize the full benefits of CCD range at the shadow end. That's probably not practical in a portable camera. Fortunately, it shouldn't be much of an issue except for really long exposures or really warm environments.

Austin writes: Isn't that a curve issue if you say it's only in the mid tones? It might be, if that were what I had actually said. But I only mentioned the midtones; I did not say that only they were affected. If you divide a 100:1 ratio of luminosity into 256 equal parts, the middle five stops (the midtones) will be divided into only 64 discrete levels, and will represent only 25% of the total dynamic range. If you divide a 1000:1 ratio of luminosity into 256 equal parts, these same midtones will be divided into 128 levels, or half of all available levels, and half of the total dynamic range. If the bulk of your image is recorded in midtones, as would be typical for most images, properly exposed, the former gamut will give you only half the tonal resolution and contrast of the latter. And if you attempt to improve contrast by boosting the increments between the midtones with an S curve, you risk posterization in the first case, but much less so in the second. This is why wide gamut shows poor contrast in midtones if displayed as-is, and why it may produce unacceptable results if you simply try to play with the curves.

I was thinking only of archived photos. For Web and e-mail use, in most cases you can crank the compression all the way up in Photoshop (that is, set it down to 1, the highest compression setting) and the image will still look fine. Unlike some editing programs, Photoshop won't let you compress the image so much that it really looks bad on the screen; even the worst setting is still pretty good. This statement I do not understand; please elaborate. Most scans, at full resolution, do not actually hold enough detail to make full use of that resolution, so compressing them into JPEGs really doesn't sacrifice anything. Additionally, with the lowest compression settings of Photoshop (level 10), I have yet to be able to distinguish between the original and the JPEG in terms of image detail, even when greatly magnifying the image. Photoshop is very conservative. Surely, this cannot be the case if we are talking about raw data as opposed to encoded compressed data even at the lowest setting in which there still is some compression of the raw data. There is always some loss in a mathematical sense and a strict sense, but in practice you won't be able to see the loss when storing full-resolution scans as JPEGs with the quality setting set as high as it will go. I've never had any problem losing detail in archived JPEGs as long as I use the highest quality setting. I sure would like to see a 16-bit version of the JPEG standard, though.

yes; if there are many pixels of same color, image will compress more. And that is almost never true for real-world photographs, although it is certainly true quite often for computer-generated images such as diagrams and the like. Wow, are you sure? The LZW TIFF was *larger*? It can be if there is a _lot_ of detail. In a lossless compression scheme, the chances of a compressed image being _larger_ than the original are always equal to the chances of it being smaller, if the image is completely random. In practice, totally random images are scarce, but the more detail an image contains, the more closely it approaches randomness, and the greater the probability that the compressed file may actually be larger than the uncompressed file.

Unfortunately, there is no way to prevent visitors to your Web site from stealing the images you display upon it. Jim's method is easily defeated (you can take a screen shot by pressing Print Screen and capture the image for later use, with or without a transparent GIF). The reality is that you cannot simultaneously allow visitors to view an image and yet prevent them from saving a copy of the image. The only option you have, then, is to not put anything on your site that you cannot afford to have stolen. In my case, I don't worry a lot, since, even if someone likes my image enough to steal it, the resolution of the image is generally too low to permit decent printing. An 800x600 image looks large on a screen, but only measures about 2x3 inches when printed at a decent resolution on a good printer. So anyone who wants a really high-resolution copy of one of my images will still have to license it from me. I can't do much about people who steal and use the low-resolution versions on my site, short of suing them, which I usually cannot afford to do, even if I find out about them. - Original Message - From: Colin Maddock [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, May 26, 2002 05:10 Subject: [filmscanners] Copyright of photos The copyright of photos on the internet had quite a thrashing on this list a few months ago, but did any solution to the problem of people stealing copyrighted images come up?

Hi, Apologies if this has been asked 1000 times before. I am looking for a flatbed scanner capable of scanning 6x6 negatives. It has already been explained to me that quality will not be as good as from a dedicated film scanner but I can only go for a flatbed (I can justify scanning images but not film). I have found an Epson Expression 1680 Pro and a Umax Powerlook III (does not seem as good). The budget is circa 1000 UKP (it can stretch but not to the price of a Umax Powerlook 3000). Other bits of info are that films are in strips of 3 negatives, the scanner would be connected to PC, and SCSI interface is preferred. The output - if used at all - will be put on the web so although the final quality may not be too high I would like to get as good an image as possible. Any advice or suggestions as to what other flatbeds may be available is welcome. Will the scanned images be any better than scanning 5x5 prints?

[filmscanners] Re: Re:Computer size(New Topic)
Rob writes: What size computer do I need so that I may work happily with Photoshop and 200M scan file size. The largest and fastest you can afford. Seriously. RAM is the most important. You should have at least a couple of times as much RAM as your image size to work at a reasonable speed ... and the more you have, the better. If you can afford and configure 10 GB of RAM, so much the better. You cannot have too much. Next, the faster the disks you have, the better. Having lots of RAM makes the disks far less important, but they should still be fast, otherwise Photoshop will nearly grind to a halt each time it needs to touch the disks. Finally, the importance of processor speed varies with the type of manipulations you perform, but here again, faster is better. A single processor at 1 GHz is preferable to two processors at 500 MHz each, since most Photoshop operations cannot be spread over multiple processors. But if you are held back by RAM or disk, a faster processor won't make much of a dent in your working speed. I now have a P3 800 / 780M ram + scratch disk. This is using sometimes 3G PShop memory and is taking heaps of time to process. Triple the amount of RAM, if your machine allows it, or simply buy and configure as much RAM as you can afford, up to the maximum on the machine. That will make a _huge_ difference. If you still see disk activity after adding as much RAM as you can, try to get faster disks. If you finally have added enough RAM to eliminate disk I/O and/or you've got the fastest disks and the most RAM you can get, and you still want more speed, consider a faster processor. Usually, though, RAM will provide the biggest jump in speed, and may well be enough alone to fix your problem. Disk will provide another, somewhat smaller jump. Processor will provide a significant jump only if RAM and disk are already adequate, as Photoshop tends to spend a lot more time I/O-bound in most configurations than it does processor-bound. You can get a feel for the influence of processor power by comparing the time required for a Gaussian blur to that required for a motion blur or radial blur (the latter requires a lot more processor time than the former, but not really any more memory or disk); the bigger the difference, the more processor-bound your machine currently is (if you see no difference, you need more RAM, or failing that, faster disks).

Even between deep shadows and sunlit highlights, the differences shown by my spot meters do not exceed half a dozen stops or so in most cases, and I don't remember any specific cases of ten-stop differences, although I'm sure there have been a few almost artificially extreme cases in which they appeared. Even right here in front of my PCs, in a darkened room with a few light sources, I can get only about a 8-9 stop difference between the brilliantly lit white ceiling above a halogen lamp and the dark shadow under a desk.

Austin writes: BW film can easily handle 10 stops, with very little effort. It can _just barely_ handle ten stops, from zero to maximum density. Since some margin is necessary in order to hold detail, ten stops is potentially difficult to achieve. Fortunately, it's not generally necessary. For many films, the tonal resolution at the high and (especially) low ends of film density is rather poor as well. Try reading up on the Zone system and compensation development. I don't need to; I have the film data sheets right in front of me, and I'm simply reading off those. In any case, however, real-world scenes aren't likely to ever tax film over a ten-stop range.

Les writes: Is there a good safe procedure for opening the scanner and accessing these parts? Not necessary on the LS-2000. Remove all adapters from the scanner. Turn the scanner on, and wait until it starts to advance the scan head towards the front of the scanner. Turn the scanner off a second or two before it reaches the forward limit of its travel. This makes the mirror and lens readily accessible through the opening in the front of the scanner. Then just blow away the dust, and _carefully_ clean the mirror if necessary (the lens is usually clean, since its axis is horizontal and it doesn't collect much dust, but you can clean it if you want). I use some lens tissue around a Q-tip, or just the Q-tip, occasionally slightly moistened with Kodak lens cleaning fluid or distilled water. Works fine. I've done this lots of times and I haven't noticed any degradation to the scanner. Keeping the adapters out and the scanner door closed when not in use helps retard the buildup of dust.

[filmscanners] Re: Advice Please
David writes: I shoot medium format (t-max 100) film and the end use is for high qualiy glossy magazines and corporate publications, usually A4, very occasionally A3. Any decent scanner will be more than sufficient for this type of work, as offset printing can't come close to the quality produced by a good film scanner. So from this standpoint, both the Nikon and the Flextight (and probably any other MF scanner) would be fine. If you want to be able to extract as much information as possible from the film for archival purposes, then you may need to look at the scanner with the best quality (i.e., highest price, roughly). Calumet, for example, tell me that the Nikon 8000ED would be more than adequate for the purpose, whereas Digital Workshop say that the Nikon would not be up to the job and I would need a Flextight III, at considerably more expense. Both would be more than enough for publication. So, first question; would the Nikon give me pin-sharp scans from b/w negs, suitable for high quality publication, at least to A4? Easily. Secondly, when the Nikon was demonstrated, the film was clearly not at all flat in the holder. They told me that the scanner had enough depth of focus to compensate for this. Is this true? Depends on what you mean by not at all flat. The Nikon is sensitive to warping of the film and I've had scans with the standard 120 strip holder that were visibly soft in areas that warped out of the focus plane. The solution is to use the MF glass holder that is available as an option for the scanner (about $350). They also said that, if it was a problem, a glass carrier was available, but I can forsee all kinds of problems with that, such as dust on the extra 4 surfaces, and newtons rings. True. I seem to get better scans with the glass carrier than with the standard carrier, though. I've only recently started using the LS-8000ED and I haven't scanned any black and white yet, but the results with transparencies are great.

[filmscanners] LS-8000ED examples
I've uploaded some more scan examples for any interested parties, scanned with the Nikon LS-8000ED. This is a scan of a Provia 100F transparency, in medium format, 6x6. The picture was taken with a 150mm lens (equivalent to 90mm on a 35mm camera), roughly 1/250 at f/5.6 or so, as I recall. The photo was shot handheld. The location was the Disney Studios Park in Paris. The scan was performed with the Nikon glass MF strip holder, 14-bit mode, 4x sampling, dICE turned on, GEM and ROC off, superfine scan (1 CCD) off, auto focus and exposure, no other adjustments from defaults. The files are as follows: http://www.smallevents.com/mousebefore.tif ... A reduced-size copy of the raw scan from the scanner. This is a 16-bit TIFF of about 2 MB; it is identical to the original, apart from being downsampled to 1/223 of its original size (from 8964 pixels on a side to 600 pixels). You can see that the entire frame is covered. The blurred stuff just to the left of the frame itself is just a reflection of the transparency on the side of the film holder. Since this is a TIFF, you won't be able to see it in your browser, but you can download it and open it in Photoshop. http://www.smallevents.com/mouseclose.tif ... An original-size excerpt from the original scan, showing detail resolution. No unsharp masking or anythign done. This part of the photo was also the original focus point in the photograph itself. http://www.smallevents.com/mouseafter.jpg The scan after adjustment in Photoshop. Adjustment consisted of changing the curves to brighten up the scan a bit and to make the color balance match the original transparency on a light table. The original transparency has better contrast, but this is the best that can be done for a CRT display. I also cloned out a tiny spot of Newton's rings in the sky in the original. If you want to see how well the scanner holds the shadows, load the TIFF and crank up the curves in Photoshop; you can see that there is more detail in the shadows than are normally visible on a CRT.

[filmscanners] Re: LS-8000ED examples
David writes: How long did that take for the scan? Hmm ... I didn't time it. Maybe 6-7 minutes, I guess. Presumably 1x sampling, not superfine (i.e. using all 3 CCDs) would be faster? How much faster, and how much worse? 1x sampling would probably be nearly four times faster, logically, but I haven't timed that, either. I don't think it would look much worse. In fact, I haven't really tried to see the difference between 1x and 4x; I only use 4x because the scan is still pretty fast, and I used to use it on the LS-2000. From French culture to American kitsch. How far the great have falleng. Well, it was a good test subject. Too bad the DOF was so deep, as the background adds a lot of clutter. Getting the original close to your result requires a major change to the blue channel. Yes, but all the Nikon scanners I've had tend to produce bluish or bluish-green scans. I don't know why. The correct usually consists of boosting red and green and reducing blue. The exact exposure of the film makes a difference, though, as I'm pretty sure there is a slight color shift in Provia in underexposed vs. overexposed areas. One thing I notice is that the red is not blinding, as it has been in most of my scans in the past. This means that (1) maybe the exposure I used made a difference (as far as I can tell, this particular shot just happens to be perfectly exposed); or (2) Provia 100F has been modified to reduce its propensity to yield very vivid reds (or the 120 emulsion is actually not the same as the 135 emulsion); or (3) the LS-8000ED does not emphasize reds, and previous Nikon scanners did (?). Historically, I've noticed that red is always almost totally saturated in Veliva and Provia scans--so much so that when I boost saturation, I usually do it only for the blue and green channels, otherwise the red will burn holes in the retina. Moving from consumer digital to scanned film, I've been quite surprised at the radical color adjustments that are required. They aren't as radical as they seem. A surprising small shift in the respective gammas for the three channels corrects the color. Also, the film itself tends to shift with exposure. My impression is that as exposure goes up (at least for Provia), the red goes up and the blue goes down. However, on the light table, the slide looks exactly like the _corrected_ version of the scan, so it can't be just the film. Maybe the scanner itself shifts colors based on exposure. I suppose that's unavoidable? I've never obtained a scan that didn't require color correction. Note, however, that I never try to correct anything in the scanner; I always make all corrections in Photoshop, and I leave the original scan relatively raw as it leaves the scanner.

[filmscanners] Re: Scanner calibration
Arthur writes: Are you sure altering color balance isn't cheating? ;-) That depends on the direction of the alteration. If you alter colors to match real life, it's not cheating at all; if you alter them to create some sort of departure from real life, it is cheating (with respect to representing the image as an image from real life). I correct colors to make sure the image looks like real life. The typical example is correcting light from streetlights on Provia so that they have the proper pinkish-orange color that HPS lamps appear to have in real life, instead of the yellowish-green rendered by Provia. The film is probably recording a more accurate color temperature than our eye does. True for blackbody light sources, not true for discontinuous sources such as discharge lamps, which don't have a real color temperature to begin with. Film will often react much differently to discontinuous sources than will our eyes, so the film rendering has to be corrected. Additionally, even if film records blackbodies correctly, to make things look real we must simulate the automatic white balance of the human eye to some extent. It's true that real-world images in shadow are very blue indeed, but we don't notice that much in real life; and if the objective of the photo is to create the same perception that we had in real life, some adjustments are necessary. As you know, we color adjust chemically and reduce the blue component we see in shadows. No chemical adjustment is required. The brain handles white balance adjustments. Direct fatigue of retinal cells is much less of a factor, and much shorter in duration.
