If it looks right, it is right, because if there is one area where this phrase applies, it is photography: If it looks good, it is good. It's just that 3"x4" web images pretty much define the lowest common denominator. Judging his assertions based on the web images doesn't do it for me. He stated that everyone agreed with him that the D30 images were 'better'. Lacking other evidence, I would have to accept his conclusion, but not based on the web images. Erwin's assertion come to mind here. If you're not using fine grain film, camera on a tripod, etc., you're not getting the most out of the lenses. Reichman's methodology introduces enough factors to degrade the Provia film's capabilities down to the level where the outcome of the test is a toss-up. This is not, after all, a test of the D30's imaging chip vs. Provia F, but a test of the D30 system, including lens (I have this lens, and while a decent performer, it is certainly not the best at any focal length), possible camera shake, camera/computer algorithms of various sorts, third party computer manipulations, printer driver/ink/paper conditions vs. similar conditions with the film path. There are scanner profiles, resolution/noise issues etc. The Imacon is good, and may be better than what most people use, but the assertion that therefore the film is not as good is silly, as the scanner is probably a lot less capable link in the chain than the film. Again, the computer manipulations, profiles, etc will reduce and change the output. Color purity is asserted to be better with the D30 than with film, but again way too many intermediate steps are introduced to come to this conclusion, and besides, he relies on his memory of what the shot should look like. Not a good basis for color comparison. He, however, likes the results better, so he's right. What he has shown, is that for his standards and his conditions, the D30 does a better job than film. That we'll have to accept. The conclusion that he draws from this; that the D30 is better than Provia, isn't close being proven. What this shows is that the digital cameras can now compete not only for P&S stuff, but also at a certain practical level of 35mm 'serious' work. And the film processing costs are a lot lower. Just don't count the 6-12mo. obsolescence of most of his equipment. You can still buy a lot of film for that. - -- * Henning J.
