my first shots with the Pentax K10D
Aside from speed testing, that is. I went for a walk today and filled a 2G card with K10D RAW/DNG exposures. I put the FA20-35 on it, used autofocus almost exclusively, and just went snapping around the neighborhood. About 120 some exposures in all fit on a 2G card. I processed the DNGs with my usual RAW conversion workflow in ACR. No noise reduction or sharpening applied, only standard RAW processing parameters on the adjustment panel. (BTW, I set ACR options to do sharpening as preview only, so absolutely NO sharpening was applied in RAW conversion.) No other processing done in Photoshop afterwards, other than to size and render for my standard web formats with Actions ... same ones I use for everything I post. The only thing I had to do different was turn off ACR's Auto processing defaults. http://homepage.mac.com/godders/neighborhood-K10D/ Please note that there are thumbnails on the index page, normal web- size pix on the individual pages, and half-rez renderings that open into a separate window if you click on the normal web-size pix on the individual pages...

K10D and Wireless P-TTL
I've never used P-TTL so please be kind to me and forgive my ignorance on the subject. The literature seems to suggest that to do wireless P-TTL you need a flash unit acting as a controller and a slave unit to provide the illumination. Does this mean that the controller does not / can not be setup to provide some of the illumination ? Say for example you wanted to do contrast control flash wirelessly.. Would it be possible to used the slave unit the main light and the controller for fill in ? or vice versa.

Here's the contrast control sync description from the manual: Contrast Control Sync Mode. This sync mode enables you to photograph with multiple flash units, utilizing the difference of the light intensity of each flash unit. The ratio of flash light intensity between the flash unit set to this sync mode and the other flash unit is 2:1. The problem with using the on board flash of the D in conjunction with the AF-540 FGZ is that the flash won't fully pop up if 540's mount clamp is tightened.

Re: SR effectiveness at 1:1 macro?
On 11/12/06, Mark Cassino [EMAIL PROTECTED] wrote: I'm looking forward to trying out SR for macro work as well. I don't expect that it will allow me to do much with available light shooting, but if it lets me slow down the shutter speed by a stop or two that opens up a lot of opportunities to better balance flash and ambient light. I currently use a monopod and A* 200, flash, and *ist-D. At 1/250th of a second I can usually count on the shot being sharp. At 1/125th the percentage of successful shots drops off significantly. At 1/60th, even with the monopod and flash, it's difficult to obtain a critically sharp shot. I don't expect SR to work miracles either but as you say even a little help can go a long way. I've read the thread and I'm not sure what you mean by 'effectively is a 137mm.' I thought that the A* lens, via the use of floating elements etc, was using a some degree on internal focusing to focus close. As such, it actually gets shorted in focal length as it is focused closer. So it _is_ a 137.5mm lens at 1:1, no? Which is why it does not need 200mm of extension to get to 1:1. You are correct, my use of effective relates to the actual FL at the particular magnification. You raise an interesting question. I take a pretty empirical approach to this sort of stuff so I'll be running some tests. I will be too, I'm just too busy to actually go out and shoot at the moment :-( On a slightly different subject - I was surprised to see in the manual that Pentax recommends turning of SR when you have the camera on a tripod. Surely a truly long lens setup on a tripod (eg 400 - 800 mm) - would benefit from SR, especially if the lenses is on a ball head (remember Paal's comments on that?) or if it is not 100% locked down (I usually shot birds with the lens in a semi-mobile mode.) I suspect that's because of the limited bandwidth of the SR system. In other words the SR system is quite slow, it's designed to compensate for the relatively low frequency movements encountered during normal hand holding. Mirror shock is often a source of ringing when shooting on tripods as most are resonant and under-damped. I expect that the SR system may over-react to these high frequency oscillations and may cause the SR system to overshoot in attempting to compensate. Given that the pre-fire timer mode disables SR I guess that they thing pre-fire is of far greater benefit for tripod shooting than SR which makes sense. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
Understanding ProPhoto RGB - or not
Hello PDML, I came across this article: http://www.luminous-landscape.com/tutorials/prophoto-rgb.shtml which is about color management. The author states that current DSLR cameras can produce colors that don't fit into the AdobeRGB color space. This is based on some ICC profiles used by Capture One and presuming that: Camera Raw within Photoshop does the same thing, except that it does so behind the scenes. His conclusion: What does this mean? Simply, that if you are using the Adobe RGB colour space with a Canon 20D, for example, (and this applies to virtually every other DSLR on the market), you are not getting a lot of the deep saturated colours that the camera's sensor is capable of capturing. While I'm still learning color management, I have some doubts about this. AFAIK two color spaces are commonly supported in digital camreas: sRGB and AdobeRGB. If I set a camera to XY color space, I would not expect to get colors which are outside of that color space. Maybe with some very wild image manipulations one could manage to hit the limits of AdobeRGB, but I doubt that such an image would print well. So does this article have any valid points? -- Attila -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
Re: my first shots with the Pentax K10D
I went for a walk today and filled a 2G card with K10D RAW/DNG exposures. I put the FA20-35 on it, used autofocus almost exclusively, and just went snapping around the neighborhood. About 120 some exposures in all fit on a 2G card. http://homepage.mac.com/godders/neighborhood-K10D/ Good grief, Godfrey. As they say, one mans trash is another mans treasure. What you call test shots I'd be delighted to call my main gallery :o) I'm always particularly impressed by worthwhile treatments of everyday objects, as they remind me of how far I still have to go to develop a good eye for such things. The thing is, I could've taken that same walk and likely would've come home with an empty card, but yet you managed to fill yours. Go figure.

It's true, the colour gamut of most camera sensors is far greater than sRGB or AdobeRGB and most aren't even fully contained within the ProPhoto RGB CS. The colours that the camera is capable of recording are clipped and compressed to fit into the Adobe RGB and sRGB colour spaces, the colours outside the selected colour space are lost at that point. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

Re: backup K10D or ... ?
Jostein, I am not Mark, but I have used several lens reversed with the D and have gotten decent TTL exposures. I have used a Vivitar 28.2.8, a Pentax A 50/1.7 and Canon FD 50/1.8 reversed on the D.

Re: Understanding ProPhoto RGB - or not
While I'm still learning color management, I have some doubts about this. AFAIK two color spaces are commonly supported in digital camreas: sRGB and AdobeRGB. If I set a camera to XY color space, I would not expect to get colors which are outside of that color space. Maybe with some very wild image manipulations one could manage to hit the limits of AdobeRGB, but I doubt that such an image would print well. So does this article have any valid points? Careful with that learning it's a bottomless pit as far as I'm concerned. I went down that road a year or so back and shored up some of my ignorance, but there's still plenty left. There are a few issues: - XYZ colorspace does not represent all colors... just all the colors that people can see. Camera sensors can capture more (think infrared for starters). - Many trichromatic (e.g. sRGB, AdobeRGB) colorspaces do not adequately cover the visible spectrum. Ones with wider (e.g ProPhotoRGB) use colors that are imaginary but can also represent more of the real colors as well: http://en.wikipedia.org/wiki/ProPhoto_RGB_color_space - Most printing techniques are grossly inadequate to represent much of the visible spectrum. IMO, if you want to keep full color spectrum, you'll likely want a very wide space: http://en.wikipedia.org/wiki/Adobe_Wide_Gamut_RGB_color_space http://www.adobe.com/products/adobemag/archive/pdfs/98auhtbf.pdf ... but to prevent posterization you'll also likely have to keep 16-bit throught all the processing. -Cory -- * * Cory Papenfuss, Ph.D., PPSEL-IA * * Electrical Engineering* * Virginia Polytechnic Institute and State University * * -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

Re: my first shots with the Pentax K10D
Boris, That's an unrealistic expectation. Both the *ist D and *ist DS are very competent cameras. You will not see major improvements at web resolution rendering between them and the K10D if you are exploiting their capabilities to the fullest. I've been completely unconcerned with the expected advantages of the K10D regarding image quality: I knew in advance that it would have improved resolution for large prints, that the upper bound of noise and sensitivity would not be a problem for me, etc. That's why all the picayune whinging about it has been nonsense as far as I'm concerned. Pentax has built a very fine camera in the D, DS and other siblings ... the K10D continues in that tradition with new capabilities regards color balance adjustability, better capture handling, speed and responsiveness, etc. In these preliminary snapshots, I'm testing more the camera's dynamics in use and new features. I'm still in the getting to know you stage of K10D ownership ... I find the *ist DS to be a very very competent camera and I'm looking for what the K10D offers that improves upon it, for my use. So far: - The overall speed and responsiveness of the K10D, both AF and IO systems, is an huge plus and worth the additional bulk and weight. - The metering system seems to be more consistent and closer to the corrent calibration for RAW capture. - The color balance control system is extremely good ... I'm still learning it, but it's the first camera I've used where i might want to use in-camera JPEG capture intentionally. - I like the fact that nearly all the features of the DS I never used ... the program presets ... are gone and replaced with features that I likely *will* use. - The Shake Reduction system will extend some of my hand-held capabilities. - The exposure bracketing options and feedback are the *best* I've seen in any camera ... this is the first camera since I've had the feature available that I consider it actually useful. - The K10D offers nuance beyond what the *ist DS offers. Image quality seems right up to par, meets my expectations for improvement over the DS. Noise is well controlled, and the bias to resolution and detailing vs smoothness is what I prefer: I can always smooth things myself, but I can't add detail. Because a complete first impression should include what I don't like ... Well, the only thing I can think of is that if I were designing the two-wheel control system, I would have placed the front wheel more to the inside of the grip and maybe at a slight angle to make it easier to use. And I might have used a different lever design on the focus mode switch to allow it to be operated without looking at it more easily. Both of these things seem to be mostly a matter of ergonomic accommodation at this point in time: I'll adapt as I get my musculature trained for the new control positions and movements. One of the things I was testing in this first set of photos was not the camera itself at all ... It was how well using Adobe Camera Raw with the in-camera DNG format RAW files would work, since Adobe has not yet released a version of Camera Raw or Lightroom that supports K10D PEF files. There's been some debate on this topic between myself and a couple of friends who's opinions I usually find credible. We disagree about Camera Raw ... They prefer Silkypix, which I find near to unusable due to its UI although it produces very good quality RAW conversions. So one of my goals in this first exploration was to see whether I could get the kind of results I would be satisfied with using Camera Raw or whether I needed to move to a different RAW processing application and workflow to get my work done. I'm happy so far that I can get what I want out of my current tool set, I'm not yet finished convincing myself that I can get the same or better quality than the others produce.

Re: Understanding ProPhoto RGB - or not
- XYZ colorspace does not represent all colors... just all the colors that people can see. It's the CIE Lab colorspace that represents the gamut of (normal) human vision. I misinterpretted his original comment and thought he was talking about CIE XYZ colorspace, not an XY colorspace with XY being a placeholder. XYZ is an absolute colorspace that attempts to model the way that trichomatic human vision functions (rods, cones, etc). Lab is another colorspace based lossless mathematical transformation of XYZ. It has the tangible benefit of providing lightness (i.e. BW) channel in addition to two color channels so it's more intuitive for people to think about. It also has the benefit of having a gamut that models all of the visible spectrum. Again, using a wider colorspace during processing *can* have benefits to the final product... even if it's printed on paper. It's not too likely, but it is possible. Basically the same argument as why 16-bit color is better for processing when only 8-bits are printable/perceptible in the final output. It should also be reiterated that if done *improperly*, using a wider colorspace will *REDUCE* the quality of the final product due to posterization or just downright errors in color profiling and conversion. Trivia: Approximately 1% of women have tetrachromatic color vision - that is, four different types of cone cells in their retinas - and can see a vastly broader gamut than normal people. Exactly 0% of men have this ability; you need two X chromasomes to get it.

Re: Request for photos
Thanks Mark and others who responded to this thread. I was thinking out loud to my wife about this last night and reached somewhat the same conclusions you did Mark... that either the person or business entity that wants to use the photos is likely going to profit from it in some manner. Ivana could just be collecting photos to compile and sell calendars, for all I know. If that's the case, I above anyone, deserve to profit from my photos. While I may 'giveaway' photos to friends or allow them to use them for free personal use, their should be no expectation by a stranger who wishes to publish my photos for a commercial use, that they come without a price attached. I also agree that the suggestion the photos could be used at the web resolution and size is not very comforting and tends to make me think that she was hoping to use the pictures without charge, which is an unrealistic expectation, nor would I give my permission for such use. I also would not send out a high resolution image file without payment in hand first to someone halfway around the world. Thanks for the good advice from all. Tom C.

Re: Request for photos
My response to Ivana follows below. We'll see if I get a response. Thanks Mark, I basically plagiarized your wording when stating the terms. Making money from the deal is not my primary concern. Neither do I wish to simply give my photos away when it's for a commerical use. -- Dear Ivana, I'm pleased you came across my photos and desire to publish them in a calendar. I wish to ask you what business you are associated with and the name of the business that would be receiving the calendars. My standard fee for using the photos is 50 USD per photo. Payment of the fee would grant a one time nontransferable nonexclusive license to reproduce 500 copies of each image effective for 30 days from date of invoice. The copyright of course would still be retained by me. I do not grant permission to use the low resolution web images for any use with or without an agreement, because of the resulting low quality that would be obtained in printiing. As you have stated I also would want the photo credit on the image with my name and name of photo, in a manner that fits in nicely with the design of the calendar, and would like to have 3 copies of the calendar itself. The 30 x 11 cm size you have mentioned seems at odds with the size of the images themselves. Would the images be presented by themselves, one per page? The images that you saw on the web were framed in black. If you do acquire the rights to use the images, I assume you would not want them with the black frame. If these terms are agreeeable to you, please let me know, or write so that we can discuss the terms.
