So, is that full frame 35mm or full frame 645? 25 mp full frame 35mm size is a tall order. How long do you expect to have to wait for such a thing? [EMAIL PROTECTED] wrote: For me, the color mask has to go. Some sort of Foveon like technology is needed. I'd like to see the pixel spacing

That would be 35mm if I did the math right. I'm guessing more than 5 years and less than 10. When my old 35mm developed a shutter timing problem which I deemed not worth the money to fix (about a year or so ago), I looked at the DSLR market and decided I just wouldn't be happy with the results, so

Hi Brad, I think I would be satisfied for a while at least with 200ppi on the largest prints I can make on a 2200 printer, let's say 12 x 16, which works out to about 8 megapixels. Since Olympus has an 8 megapixel CCD on the E300 Evolt already, I am waiting for them to put it on an E-3, or

It's been several years, but I seem to remember that when I got my Nikon 4000ED filmscanner they were claiming a Dmax of somewhere around 3.5 to 4.0, but I measured it (by scanning a Kodachrome IT8 target slide and examining the greyscale separation) at around 2.1 to 2.9 (don't remember the exact

Hi Berry, Austin, with respect to your last sentence, isn't the point really that the contrast range of negative film is greater than slide film? I'm not sure what contrast range is, but I know what density range is. Slide film has less exposure latitude, and records on a higher density

When you scan negative film, the histogram is narrow. So I would say negative film has a low dynamic range.[Yeah, I know slide and negative film is really the same.] I think I see the confusion here (or specmanship). The dynamic range of a dataconverter is related to the number of bits, since the

From: Andrew Skretvedt In evaluating a film scanner, one should consider its dynamic range. How deep can a scanner reach in and pull out shadow details from a very contrasty slide, for example. What about one that might have been underexposed a bit as you tried to keep from blowing out
