Re: RES: The Great Scanner debate  - round one

How many people are scanning graphic arts film? If they are developed for
continuous tone, would it not be most likely that the DMax would be lower than
when developed in lith developers? And, if developed for very high
contrast, then perhaps it is a moot point. Most scanners can distinguish between
black and white—you could do that with a "2 bit" scanner and it would be much
the same as scanning an imagesetter negative.

But going back to my original post on the capabilities of scanners as
represented by manufacturers. I think it is prudent not to take the numbers you see
in the advertisements as a representation of what practical density the
scanner can truly scan and produce useable image information without a lot of
noise.
