Re: Nikon D80 Hands-on Preview What do "stops" have to do with the quality of an originally created file in bit depth??? You mean exposure latitude? Compared to digital? This I knew, no point in turning a 36/12 or 24/8 file into 48/16, as nothing is gained in image quality by doing it. But that's what Photoshop does with my 36/12 files anyway. other than that... Well, there is every point in a sensor's capability to create a 48/16 bit file to begin with. That's what I am yakking about. Once a 48 bit file enters Photoshop, Photoshop then calls it 16 bits. That means 16 bits red, 16 bits green, and 16 bits blue = 48 = perfect. And that's the only way to do it, as originally hardware created. Look at something called "posterization" in lower bit files. THAT adds up to "less" color and detail. You cannot add detail in photoshop to a 24/8 bit file and call it an honest original in pure photography, unless it is an *intended* work of art, as such. My point is the chip's capability, which isn't enough. However scanning a trans- parency to 48 bits IS enough even if you gain limited enlargement capability as a result of the size of the film. Film is pure imagery by chemical flow, there are no pixels involved there. The size of the film determines how big the scan can become, which in turn determines how big the final print can become. Sensors that deliver 48 bit files do exist. Currently mine delivers 36/12 bits, until I upgrade. It's a scanner. I remember a few years ago (maybe two), there were massive arguments in the digital NG concerning all this crap, mostly against the Foveon chip and for the "Bayer" and CMOS designs. Doesn't matter to me. If a scanner can do it and a camera cannot, I'll take the film and the scanner. How confused am I now? Because I feel the resulting image is what matters, and whatever it takes to attain it. -- }<)))*> Giant_Alex cravdraa_at-yahoo_dot-com not my site: http://www.e-sword.net/ AAvK
