Phil's point about razor-sharp slides coming out fuzzy as 8 x 10 prints doesn't merit a smile-face; it's a phenomenon I've run into myself, and it mystifies me. I do not own developing and enlarging equipment, and am at the mercy of commercial firms that are still willing to do black & white work. I've gotten contact sheets back that, when examined on a light table with a magnifying loupe, showed fine detail all the way through. When enlarged to 8 x 10, about 75% of the print--mainly the center--was sharp; but the corners were blurry, thus ruining what otherwise was a really good photo. I've heard explanations that the enlarger lens was faulty; and I've heard that's impossible in a good commericial shop. Anyone have any experience with this? -- Ken Wolman Bell Communications Research @ Livingston, NJ lcuxc!kenw You can't "read" me because I'm not a book.

This happens because of carelessness of mounting the negative in the enlarger. Most negative carriers used to hold the negatives have little projections which are supposed to keep the negatives flat. Some don't, though. If you're at the end of a roll of film, or the negatives were left too long in a heated film dryer, the negatives can be curled a lot. So when the enlarger is focused on the center, the edges of the negatives end up being out of focus because they are at different distances from the enlarger lens, and hence out of the plane of focus. The simple cure to this problem is to use little pieces of masking tape on the edges of a curly negative to make sure it's flat. I would guess that it would be too much hassle for most commercial shops to take that much time and care when they want to keep their costs down. I would take the unsatisfactory prints back, and demand that they take the care that is required to make a good print.

Anyone have any experience with this? >Ken Wolman >Bell Communications Research @ Livingston, NJ >lcuxc!kenw If the slides are not glass-mounted, then they are never completely flat, so if the enlarger is focused on the center - the edges may be blurred. If I understand the principle behind depth of field correctly, this can be minimized by stopping the lens down (it should work "backwards", i.e. not only in cameras). But that means longer exposure times and I have yet to find a commercial lab that would be willing to slow down their tempo for the sake of their demanding clients (maybe .001 % ?) By the way, my experiences with processing labs, excluding Kodak, are disastrous, and I would like to hear some comments about that from other people. E.J. Behr, UCSD (sdcc6!ix654)

My experiance was of a much more destructive nature. I took my precious roll of B&W to a private lab for a contact print. Came out perfect. Upon examination with a loupe, I selected a couple that were exceptional and had 8X10's made. The prints had a few very obvious scratches on them. The lady at the lab said I should get my camera serviced. Well, OK, I *did* buy the camera used, but it's funny that none of the color prints had scratches on them. (The color shots went to Kodak.) By then a strong pattern was developing, but like a drooling idiot I resubmitted one of the negitives for re-printing. They had done a horizontal crop when I had ordered a vertical one. Anyway, the second print had NEW scratches at RIGHT ANGLES to the previous scratches. I politely pointed this out, having right there on the counter the previous prints, and they offered to do some touching up for free. Great, but now my negs are destroyed. I never went back there. I guess the moral is, there are labs, and there are labs. Try one a couple of times, and if they're mashing your shots, go elsewhere. Anyone with enough money can buy the necessary equipment to open a photo lab. Doesn't necessarily mean he (or his employees) knows what the hell he's doing. My best results have been with an industrial quality photo lab in this area. They are hideously expensive, but the quality is truly amazing, and they can fix a shot you've badly over or under exposed. A major drawback is they require a minimum order. They're not interested in fixing your vacation photos. For normal stuff, you can't go wrong with Kodak. -- __ Ron Christian (Watkins-Johnson Co.

Ditto, ditto. For years I did all my Black and White myself, good B&W
is fairly easy, it does take a little time. All my color work goes to
Kodak, which has never messed up anything permanently, and you can always
reject prints that to your taste, weren't done right. I've never had any
body even question me when I sent stuff back. What's really neat is that
I live close enough to the tranparency developing facility that I get one
day service on slides.
I did once take a picture of a yellowed painting under available light
with Daylight film. The colors on the slide are understandably lousy.
When I had an 8x10 made up, Kodaks color banancing wizmo color adjusted
the whole thing so that it looks almost natural (better than real life).
Of course they've messed things up also, causing a picture with some red
in it to turn almos purple.

I wonder if other people are as dissatisfied with Kodak's quality for color enlargements as I? I've found the difference between Kodak and a professional color lab to be remarkable. It is evident Kodak (at least the lab in their San Francisco area) does not take the time to get the color right and focus just perfectly like a reputable color lab does. However, I pay for it; the color lab costs about twice as much as Kodak. So I use Kodak for snapshot enlargements and the color lab for my more serious photography. -- Rob Bernardo, Pacific Bell, San Francisco, California {ihnp4,ucbvax,cbosgd,decwrl,amd70,fortune,zehntel}!dual!ptsfa!rob _^__ ~/ \_.\ _ ~/ \_\ ~/ \_________~/ ~/ /\ /\ _/ \ / \ _/ \ _/ \ \ /

You sure are right about Kodak lately. Their quality control has really bitten the dust. I have worked at many camera stores in the Boston area, and have seen a great deal of photofinishing come through. Kodak has lately been (lately being the past 2 years) scratching negatives, using improper color balance, using bad chemicals, not focusing enlargements, doing shoddy copy slides, losing lots of film, etc. Personally, I sent an enlargement back 4 times, calling them about it once because the thing had so much cyan in it it was pathetic. They told me they couldn't do anything about it, and sent the identical photo back all four times. When I told them I was a photo employee, they said they'd fix it, and again sent back the identical photo. I gave up. Unfortunately, most retail photo labs are as bad, if not worse. You either have to take your chances, or spend megabucks for a custom lab. Mikki Barry

My experience with "The Great Yellow God" has been mixed at best. I've had some really good work from them, and some VERY bad stuff. Most of my problems with them stem from printing from color slides. Although I've yet to lose a slide to scratches, etc., some of their work has gone back four and five times! (When things REALLY get bad, I remind them of their PRINTED warrantee, and send a copy to Rochester.) My worst experience occured about a year ago when some klutz in the So. San Francisco processing plant opened one of my rolls in a "not quite dark" room. When I bounced the pix (prints), I received a "Short Note" stating that I had opened the camera back, thereby ruining the roll. Such was the light problem that there was no way that such a thing could have happened. Anyway, after getting pretty nasty with So. SF, and contacting Rochester (and telling So. SF what I was doing), things suddenly (within 1 week...after 5wks of hassle) got straightened out. My roll of film was replaced, Kodak Rochester and So. SF sent me letters of apology, and things were all back to normal. (It pays to make LOTS of noise.) All in all though, Kodak has been pretty good to me. Considering what I shoot (nature, gymnastics [try that if you REALLY want a chalange], existing light portraits), I don't think I'll change...at least not yet. BTW, the tip I read about going to an inter negative for printing from slides sounds good. To who(m)ever...thanks. -- Chip Kozy (415) 939-2400 x-2048 Varian Inst.
