RE: DOF and format size
Anthony wrote: What you missed is that as film formats get larger the lens needed to get a certain angle of view also lengthens, so the amount of DOF getting onto the film in the first place is less. With very minor variations, the depth of field is a function of angle of view rather than focal length. Thus a suitable lens selected for 4X5, or 8X10 for that matter, will have the same depth of field - aperture for aperture as the 35mm counterpart. This applies as long as the reproduced images are the same size and not enlarged the same degree. In addition, a large format lens such as the 65mm Rodenstock Grandagon N offers its highest resolution at apertures between 22 and 32. The depth of field will be enormous although one would argue that diffraction will cause degradation. True, however the negative is almost 4 times the size that of a 24x36 35mm frame. What is also missed is that current 35mm films cannot capture the resolution of some of our higher quality lenses. In 4X5 photography the lens need to only be 1/4 as sharp (which is not the case) as lens for 35 mm to deliver the same amount of sharpness. Bob - This message is from the Pentax-Discuss Mail List.

RE: Pentax digital info
Don't forget that the bigger the chip die size the lower the initial yield. Possibly they have found that they can't produce enough good chips to meet their contract requirements for both Contax and Pentax so Pentax may have bowed out because they could not get guaranteed enough chips to have the required number of cameras for sale at introduction. Lots of possible scenarios. Maybe a low yield on the contract allows them to charge more per chip and Pentax didn't want the camera to get even more expensive while maybe Contax didn't care because their target consumer tends to be more affluent than Pentax's.

RE: K2 shutter vibration question
That's one reason my astro cameras are KX's and one Yashica Electro-X. They all have mechanical MLU. Very important on short exposures like the moon and planets. For longer ones you can just hold a black sheet over the telescope objective and wait a few seconds till all vibrations will have stopped and then pull it away to start the exposure. Kent Gittings -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Peter Spiro Sent: Thursday, October 25, 2001 11:26 PM To: [EMAIL PROTECTED] Subject: RE: K2 shutter vibration question Various tests have found that small differences in camera vibration can make big differences in resolution at moderately slow shutter speeds. People on the Olympus list have tested their cameras with or without diaphragm pre-fire, and it turns out that even the vibrations from the diaphragm closing down makes a substantial difference to resolution. This is apparently not something you can solve by locking the camera down, no matter how rigid the tripod. It seems to occur not because the camera moves, but because its body vibrates. I suspect that it has to something to do with the fact that the metal in cameras is mainly brass (the same metal used in musical instruments because it vibrates so well). When Keppler did a test (POP, June 99) of cameras with and without the mirror locked up, the biggest difference was around 1/15th of a second, where locking up the mirror could increase the resolution from a 135 mm lens by 80%. If you use a long exposure, like a few seconds, it won't make that much difference, since the vibrations will occur only for a small percentage of the time the exposure is underway. With a 5 second exposure, Keppler found that there was no difference in resolution with or without the mirror locked up. This might be why Mark Roberts likes his K2 with small apertures, long shutter speeds. When Popular Photography tested the K2 (December 1976) they reported the shutter vibration was about 0.7 volts, double the average of cameras tested up to that time. (For the cloth focal plane shutter MX, by contrast, the vibration level was about 0.2 volts). An easy subjective test you can do at home goes as follows: Set a small shot glass with about half an inch of water in it on top of the flash shoe, fire the shutter and watch for the ripples. You will find that you get much bigger ripples from a K2 (mirror locked up) than an MX or ME (mirror not locked up). As somebody suggested, it is possible that the K2's vibrations are mainly when the second curtain of the shutter hits the far end, in which case it won't cause much of a problem. Anybody who has a K2 can test for this quite easily.Lock up the mirror, set the shutter speed to B, and release the shutter with a cable release, holding it open. Watch for ripples in the water. If the camera is good, the ripples should be minimal. Then let the shutter close, and see if most of the ripple action is concentrated at that end of the cycle. I hope somebody tries this, and reports back to the group, to clarify this issue. I will be happy to revise my opinion of what is in many ways a fine camera. (I just did this test with my MX, at 1 second exposure, with the mirror locked up. Vibrations when the shutter opened were almost non-existent. BTW, on my MX the quasi-MLU does not seem to work at B.) _ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp - This message is from the Pentax-Discuss Mail List.

RE: DOF and format size (was: Re: Pentax Digital NEWS - FULL STORY from AP 27th OCT.)
I totally agree with your assessment of DOF. In addition I think the perceived DOF of digital prints is as good as it is possibly because as long as the DPI of the blowup is less than the eye can perceive and lower than the pixel count of the original image the DOF doesn't appear to shrink as the print gets larger. This maybe the reason 3-4 MP images looks so good in 8x10 blowups and why digital doesn't really have to match the theoretical 32 MP performance of fine grain film. Something to consider in the overall equation. Be interesting to try this with a digitally scanned negative or positive image and see if it holds as you get larger blowups compared to using an enlarger on the original negative. Anybody want to do a report on this? Kent Gittings -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Anthony Farr Sent: Friday, October 26, 2001 1:10 AM To: [EMAIL PROTECTED] Subject: OT: DOF and format size (was: Re: Pentax Digital NEWS - FULL STORY from AP 27th OCT.) - Original Message - From: dave o'brien [EMAIL PROTECTED] (snip) DOF has to do with the focal length and the f-stop. Print magnification has nothing whatsoever to do with it. - But print magnification has EVERYTHING to do with it. Until now I have kept my silence WRT this subject but no more. Too frequently anecdote and intuition have been been offered as informed knowledge. The facts follow. The DOF concept is based on the circles of confusion (COC) of the out of focus part of a photograph being either smaller than the unaided eye can appreciate, in which case the subject matter will seem acceptably focussed, or large enough for the same unaided eye to see the unsharpness of it. Quite simply, when the enlargement factor of a print is increased then the COC of nearly focussed areas will become larger and will cross the threshold between small enough to pass as sharp and large enough to be deemed unsharp. Photographers who either criticise or praise different sized formats for their DOF characteristics are correct only as long as the developed film or a contact print (or 1:1 enlargement) is being viewed unmagnified. Otherwise, a 22mm standard lens on a 110 camera will produce the same DOF as will a 43mm lens on 35mm (the statistical standard lens), or a 75mm lens on 6x4.5cm, a 90mm lens on 6x7cm, or even a 320mm lens on 8x10in, as long as the shooting aperture is always the same and the prints being judged are always the same size, and regardless of differences in DOF of the unenlarged negatives. WARNING: ANECDOTE AND SUPPOSITION FOLLOWS. Digital cameras seem to bend theses rules somewhat because the imaging chips have optical characteristics of their own to confuse the equation. CCD pixels prefer to look straight ahead unlike film which easily accepts exposing light from oblique angles (the apparently fatal flaw of the full frame Philips chip proposed for the MZ-D). That narrow acceptance angle may lend CCD produced images more apparent DOF (my guess anyway) the same way as the CCD array in a scanner has great DOF even without a lens. That's my ~theory~ anyway for the long DOF that some list members have reported from their digicams. BTW the DOF scale on lenses for 35mm cameras are more suited to viewing as projections rather than as prints, and even when they're printed the overwhelming majority are 4x6in minilab prints. PS 35mm and smaller or low end digicams most often have small aperture wide angle lenses so have greater inherent DOF to begin with. Medium and large format photographs almost always end up as prints for sale or for serious scrutiny by serious amateurs. It's no wonder that their DOF of is more critically judged.

This time line was reasonable since the mailing from Alaska is 5 to 7 days, and the procedure isupon their receipt of the camera they evaluate the needed repair and mail you an estimate of the costthen wait until they receive your approval to do the needed work (when done through the mail this requires three consecutive mailings before they have a approval to complete the work (~20 days consumed by mailings).

Pentax AF viewfinders
One of the things I've noticed with the modern AF cameras is the overall degeneration of the viewfinders compared to mechanical cameras. The image is smaller, less bright, and they never cover the entire image area (neither does the MX, but it shows more than the MZ cameras). At least not the Pentax ones. Why is it so difficult to put a decent viewfinder on the newer models? I've compared of course the LX, but also MX, with the MZ-3 and MZ-S and the difference is apparent. I just don't get it. First I thought it was the high eyepoint, which is the only thing that's better with the AF bodies. Holding a N for a while made me understand that you can have both. It can't be because of the integrated flash either, since even the horrible Nikon F70 has a better viewfinder. Is it to minimize the size of the camera? Or is it simply for cost reasons? Either case it's a lousy tradeoff. Anybody got a clue? I haven't really bothered until I got the MX as a backup body, only to discover that I like the viewfinder in it so much more. I was thinking of saving money for a MZ-S, but I really think that a pro-level body should be equipped with a topclass viewfinder. /Erik - This message is from the Pentax-Discuss Mail List.

Re: LX History (was: Re: LX on eBay -- worth buying?)
This got me thinking. Why above 535?? Is there a website or other source of info that chronicles the LX ? Especially with reference to serial numbers versus time ? http://members.iinet.net.au/~cam/serial/ This link doesn't contains enough serials/date to be of help when inspecting an LX, trying to find out when it was produced via its serial. First, as it's been said here, the base plate can be easily changed so do not only rely on the serial number to estimate the production date of an LX. Second, these cameras needs CLA every ten years or so. And it goes from a very simple CLA to CLA AND a full exchange of every mechanical part of the mirror box. So nowadays the vast majority of LXes have already had at least one CLA and upon the request of the owner it can have been only CLA'ed or CLA'ed AND updated. Third, these cameras were expensive and mostly used by pros and often abused... I have owned 3 LX in my life... My first one was a 535 late model and have clearly been used and abused by it's previous pro-photographer owner (who bought it new)... I sold it long time ago for a very small sum as it needed a serious rebuild of some internal mechanical parts (not even mentioning a very rough cosmetic presentation). My second one was a 523 (from memory) that has seen very little use, was almost perfect cosmetically and I used it only for some studio photoshoots. As it was really nice, I was afraid to take it for night/action shoots...using my beat-up black MX or my Super A for these It is now the property of a fellow PDMLer. My last one (and currently my main Pentax body) is a 530 that has seen moderate use from it's previous owner, and that shows some wear marks... I'm not afraid to take it with me even for some risky shoots were he might receive some more marks...although I take great care of my equipment, you never know what can happen ! All this leading me to the conclusion that it's almost impossible to know only from an LX serial number its features... You need to know its former degree of use (and sometimes abuse) and it's CLA history... From the serial number you can only estimate its production date...unless someone is able to list and time-stamp all the numerous (80+) versions of the LX.

RE: upside down and backwards?
David Brooks wrote: I know the image on the film is upside down,same as our eye see's it only the brain flips it. My is is it upside down and backward or just upside down on the film. Hi Dave, Each point in the object plane is ~inverted~ through the center of the lens to transform into the corresponding point in the image plane. This inversion operation must be symmetric with respect to rotation about the optic axis, since this is the symmetry property of your lens. Thus, an object point ~above~ the center of the lens corresponds to an image point ~below~ the center of the lens. Likewise, an object point to the ~left~ of the center of the lens corresponds to an image point to the ~right~ of the center of the lens, and so forth. The confusion arises because of the fact that you can view your processed film from either the emulsion side or the back (non-emulsion) side. The act of flipping your film over from front side to back is a ~reversion~ (i.e., left becomes right, but top does not become bottom). This operation doesn't have the same symmety property as your lens. This is probably more easily demonstrated with an example. Imagine, for example, that you're making an exposure of someone standing in front of your camera, and that you're standing ~behind~ your camera. Everything you see toward the top of this person will be imaged onto the bottom of your film, and everything you see to the left side of this person will be imaged onto the right side of your film. Keep in mind, though, that left and right in this case are with respect to your position ~behind~ the camera; thus, you're looking at the back side of the film. If you go around the front of the camera so that you are now looking at the emulsion side of your film, left and right are reversed. Bottom line, then, is as follows. If you're viewing processed film from the back side, the picture is ~inverted~ (top to bottom and left to right, or upside down and backwards as you describe). If you're viewing processed film from the emulsion side, the picture is ~reverted~ (top to bottom, but not left to right -- upside down, but not backwards, as you describe). Hope this helps.

Lens Fungus and Irradiated Mail
I was reading the news regarding the USPS begining to irradiate our mail and I got to thinking about the problems that would cause when sending undeveloped film through the mail.

RE: DOF and format size
Almost, guys. DOF is based on the diameter of the aperture. f is a function of relative light availability, not DOF. It is an exposure function only. Take your 50/1.4 lens. (roughly speaking) Lens diameter x 1.4 = film plane diagonal. A lens of f1.4 on a 4x5 would be about 4.5 in diameter! Put that same 1 aperture on a 4x5, 150mm lens, and it's (again, roughly) f5.6. DOF is the same, but light transmission changed. As a consequence, with the same aperture, shutter speed is longer with the same opening -- because the film plane is larger and needs more light to cover it. To get roughly the same DOF between formats, shooting 35mm @ 1/125 @ f8, you'd be using 1/8 @ f32 on 4x5 or 1/30 @ f16 on a 6x7. Roughly 2 stops difference from format to format. Don't confuse aperture with DOF. The relationship is only an indirect one. Collin - This message is from the Pentax-Discuss Mail List.

I've heard in a couple of places, most recently last night on NPR, that they're going to use some sort of electron radiation to start with. Apparently, this isn't as strong as x-rays, and will only be used on letters, not packages. It can't penetrate very far, so it wouldn't work on anything else. Also, they'll only be doing it to mail heading to the White House or Congress, or other similar high profile destinations. Supposedly they're exploring other options, including x-rays and gamma rays for the future. tv - This message is from the Pentax-Discuss Mail List.

Digital Advances
Pentax now has 2 Optio models listed on the US site. The 330 and the 430. Looking @ the features of them, I wouldn't be surprised to see that they're Epson electronics with Pentax glass. Anyone out there know for certain? Collin Here's some text from the page: Within its sleek stainless steel exterior, the Optio 430 digital camera features a 4.13 megapixel, 1/1.8 inch CCD and an optical 3X zoom lens. Within its sleek stainless steel exterior, the Optio 430 digital camera features a 4.13 megapixel, 1/1.8 inch CCD and an optical 3X zoom lens. The Optio 430 offers a choice of three autofocus settings. Seven-point autofocus covers a wide area of the frame and allows the subject to come into clear focus. Spot AF allows you to pinpoint the focus in the center. Free autofocus provides greater compositional freedom, allowing you to place the center of focus anywhere within the frame that you choose. - This message is from the Pentax-Discuss Mail List.

RE: Pentax Digital NEWS! Part one
Actually except in the 60's they never had the might to challenge C or N. Only their loyal momentum kept them up near the top. As it is they are the leader still usually in PS so the Optio line looks like they have begun to switch over to digital. In high end cameras they don't have the infrastructure to compete with the top 2 who usually lose money on the pro stuff and make it back on the rest by convincing people the quality is the same as the pro stuff (which it is not). Being the smallest company and without the resources of conglomerates behind them like the other 3 they can't afford to pop up with pro cameras at will without knowing in advance they can sell enough to make money. Remember the prime job of the camera is something to hold the media up so the lens can form an image. And while both Pentax and Minolta have excellent pro lenses neither makes enough models to suit any of the pros I know personally. And the ones they do generally require a long lead time because they are special order, or you have to find them used. And the top 3rd party pro lines are made in Pentax (not as much as Minolta however), but just try finding, for example, a used last generation 500/4.5 Sigma in Pentax AF mount. Good luck with that. So who is going to buy a high end 6MP Pentax 35mm lens digital camera for around $7000? Certainly not the Pentax user who is using a PZ-1p/MZ-3/ZX-5n as his primary camera. He'd have to sell everything including his lenses to afford it. It just happens in marketing that a company making a good product that doesn't sell is in lots worse shape than one that doesn't make the product at all. Besides I'm sure one of the secret marketing criteria was how many MZ-S bodies they sold initially. If they can't sell their target with a $1400 body how can they justify a $7000 body? Just coming out with a great product like that is a sure way to go into the red and go under when you can't sell enough and you don't have big pockets behind you. The others know they have a ready market because of the investment in their pro glass most high end users have, which Pentax and Minolta can't say. I applaud Minolta for bringing out the Maxxum 9 and keeping at least one pro caliber body at the top of their line. I'm also sure they aren't making that much on them overall, especially with the Maxxum 7 out. I think Pentax probably made the correct, although possibly less popular decision in this case. A cheaper body with less resolution that possibly costs only a few hundred over an MZ-S is more likely to attract the Pentax loyalist to actually buy one, instead of screaming about not paying $7000 for the other one. Nothing Pentax and to a lesser extent Minolta brings out is going to convince a high end Canon or Nikon shooter to switch to Pentax or Minolta unless their is only one lens they use. Unless Pentax decided to bring a body out that used Nikon or Canon lenses. Unfortunately that would most likely sell better than one using their own line simply because the potential buyer list is much larger.

Part one Wasn't there a time when Pentax actually cared about being a leader? Are they now content with always following (more and more distantly), at best offering products close to the others and cheaper? This would be sad. If they simply don't have the might to compete against N and C* anymore, at least they could do one thing really well - in the digital realm, this could have been the full-frame CCD SLR. Is Pentax to become the next Contax, who was fifteen (or however many) years late with autofocus? Maybe Pentax will release a fantastic digital SLR in 2016 when almost nobody remembers who Pentax is. In any case, they really have to release something serious soon or they'll be wiped off the map. (I don't care about digital products too much, I just want them to stay in business so that they can make lenses and film cameras for a while longer.) Olympus seems to be a model of a company managing their resources well and focusing on certain distinct areas very wisely. Pentax brand loyalty goes pretty far - the next couple years may be a test of just how far. Good point but if Pentax does We're no worse than the rest but it costs less ( we hope ).

Re: DOF and format size
What you are missing there is aperture size. As your focal length goes up so does the diameter of the aperature for a given f-stop. The larger aperature (not f-stop) means a larger circle of confusion. If you make an 8x10 print from a 35mm and from a 4x5 the magnificaton stays the same (with reguard to the subject to image size), but while a 50mm has a aperture of 25mm at f2.0, a 200m has an aperture of 25mm at f8.0 so to get the same DOF you would need to set your 200mm 4x5 lens at f.8.0 and your 35mm 50mm lens at f2.0. The problem most folk seem to have is from us using f-stop and aperture interchangablely. The strictly speanking are not the same thing at all. Note in the forgoing example both lenses have a 25mm aperture while the f-stops are far different. --graywolf - Original Message - From: William Robb [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, October 26, 2001 1:31 AM Subject: Re: DOF and format size I am not quite sure about this.

RE: Lens Fungus and Irradiated Mail - Is the Sky Falling?
Shel wrote: What I read is that the proposed system will be using electron beams, so perhaps we're making some headway in finding out if the system will damage film or not. Any further comments by those in the know about these things? I heard this as well on NPR yesterday on the way home from work. They didn't say anything about the typical electron current or electron energy of these electron guns. They ~did~ say, as many on the list have already noted, that the penetration depth isn't very large, so that letters would likely have to be laid flat for this to do any good. One thing energetic electrons are very good at doing is ionizing things, so it may be that at least part of the bactericidal action is due to localized generation of nasty oxidizing agents like ionized molecular and atomic oxygen, ionized nitrogen, etc. Another thing energetic electrons are good at doing is knocking core electrons out of metal atoms, resulting in X-ray emission. In fact, this is exactly how an X-ray tube is constructed -- an electron beam of several kilovolts to a few tens of kilovolts impinges on a metal target, like copper. Could be that the damage to film would arise due to X-ray emission from electron bombardment of the metal cassettes and metal spools used in packaging roll film. I also heard the same NPR commentator make remarks regarding use of gamma irradiation facilities for mail. Current facilities in the US are used for sterilization of foods and medical devices, and they apparently would not accept mail for gamma sterilization. A new gamma irradiation facility might cost somewhere in the neighborhood of several million USD and take up to a year to build. IIRC, the commentator stated that several hundred such facilities would be needed to irradiate all mail in the US. Thus, widespread use of gamma sounds like it will not be feasible. God help the poor SOB who ships a fungus-infected lens. Imagine the consequences if some postal employee -- or FBI agent, Secret Service agent, INS agent, etc., etc. -- recognize the fungus as some unidentified biological agent. Yikes!

Shutter Vibration Tested (RE: K2 shutter vibration question)
The following is from Peter: Date: Fri, 26 Oct 2001 03:25:33 + From: Peter Spiro [EMAIL PROTECTED] Subject: RE: K2 shutter vibration question Anybody who has a K2 can test for this quite easily.Lock up the mirror, set the shutter speed to B, and release the shutter with a cable release, holding it open. Watch for ripples in the water. If the camera is good, the ripples should be minimal. Then let the shutter close, and see if most of the ripple action is concentrated at that end of the cycle. I hope somebody tries this, and reports back to the group, to clarify this issue. I will be happy to revise my opinion of what is in many ways a fine camera. (I just did this test with my MX, at 1 second exposure, with the mirror locked up. Vibrations when the shutter opened were almost non-existent. BTW, on my MX the quasi-MLU does not seem to work at B.) Hi Peter et. al.: Okay, Peter, I tried the water test with the following cameras: SPII K1000 MeSuper LX K2 I did this with much trepidation as I had a bad experience Wednesday with water and camera combination (I dropped my Super Program in creek! Yikes, what a feeling!) I put each camera on a wooden cutting board and put a wash rag under the lens to cushion it a bit. I balanced a coffee mug 2/3 full of water and fired the shutter in B and watched for ripples. I re-ran all the cameras several times, checking again and again and finally checking the cameras in order of ranking. In general, the initial slap of the shutter was much less than the return. I would say roughly 50% less. Suprising to me was that the mirror lock up did make more difference than it did. The following would be my SUBJECTIVE ranking of initial vibrations-- Top 2 were close but 1. k1000 (very short waves, low amplitude) 2. LX - mirror up (similar to k1000, longer waves) Another close grouping 3. SPII (slightly longer waves than No. 2) 4. LX - mirror down (very similar to the SPII, slight more amplitude) Much worse than above 5. K2 - mirror up (long wave, a bit more amplitude than No. 4) 6. K2 - mirror down (a bit longer wave and amplitude than No. 5) 7. MeSuper - (longest wave, amplitude) The return curtain vibrations rankings were similar, maybe less difference between the LX, SPII grouping and the K2 MeSuper grouping. And I love that MeSuper!

Re: Flocking Material
Hi Shel, Back in the sixties, people did some absolutely atrocious things to automobiles with paint that produced a velvet look and texture. It was flocking terrible stuff. I know it came in black, and I bet someone still sells the wretched stuff. And while it may be awful for almost any application, it would probably work quite well as a coating for the inside of lens hoods.

Re: Flocking Material
I looked through my Micro-Tools catalog and could not find any flocking material or flocking paper but you may want to go to: http://www.micro-tools.com Then select the USA and look in the leftmost column for restoration supplies. I saw various sizes of light baffle material that may possibly be used to reduce reflection from the inside surfaces of lens hoods. Anyway, it's a lead. You could also seek a source from a TLR repair service. I think flocking material is used extensively in the camera bodies.

Re: Minolta Dimage Scan Dual Do's Don'ts

Re: LX History (was: Re: LX on eBay -- worth buying?)
I look for three things in a used LX: good overall condition, the second meter button on the exposure compensation dial, and the 3200 asa setting on the film speed adjustment dial. If it has all of these, it can generally be repaired and adjusted for good service. Paul Jerome wrote: This got me thinking. Why above 535?? Is there a website or other source of info that chronicles the LX ? Especially with reference to serial numbers versus time ? http://members.iinet.net.au/~cam/serial/ This link doesn't contains enough serials/date to be of help when inspecting an LX, trying to find out when it was produced via its serial. First, as it's been said here, the base plate can be easily changed so do not only rely on the serial number to estimate the production date of an LX. Second, these cameras needs CLA every ten years or so. And it goes from a very simple CLA to CLA AND a full exchange of every mechanical part of the mirror box. So nowadays the vast majority of LXes have already had at least one CLA and upon the request of the owner it can have been only CLA'ed or CLA'ed AND updated. Third, these cameras were expensive and mostly used by pros and often abused... I have owned 3 LX in my life... My first one was a 535 late model and have clearly been used and abused by it's previous pro-photographer owner (who bought it new)... I sold it long time ago for a very small sum as it needed a serious rebuild of some internal mechanical parts (not even mentioning a very rough cosmetic presentation). My second one was a 523 (from memory) that has seen very little use, was almost perfect cosmetically and I used it only for some studio photoshoots. As it was really nice, I was afraid to take it for night/action shoots...using my beat-up black MX or my Super A for these It is now the property of a fellow PDMLer. My last one (and currently my main Pentax body) is a 530 that has seen moderate use from it's previous owner, and that shows some wear marks... I'm not afraid to take it with me even for some risky shoots were he might receive some more marks...although I take great care of my equipment, you never know what can happen ! All this leading me to the conclusion that it's almost impossible to know only from an LX serial number its features... You need to know its former degree of use (and sometimes abuse) and it's CLA history... From the serial number you can only estimate its production date...unless someone is able to list and time-stamp all the numerous (80+) versions of the LX.

Re: Applying Lipstick
Hi ... You're right about the white light. There was little I could about it do wrt to exposure and development to tone it down. Less development would have muddied the print even more and ruined what little contrast there is between the woman's collar and her face and sweater. Had the print been made in the darkroom I'd have burned that area a bit. PS 6.0 has a feature that will allow dodging and burning, and even the scanner may have a way to set the levels. Of course, I don't know how to do that yet, but learning is just a matter of time. Your comment is right on the money. BTW, the film used for this shot is TX ... compare the grain structure of the current TX with that of the older TX in the photo of April. The developers used were similar, but the newer TX seems to have a finer, smoother grain pattern without losing accutance, and a smoother tonality. It may just be that my poorer skills in the early days contributed to the grain difference ...
