In comparing two different film scanners one has an optical density of 4.2, the other (and more expensive) 4.8. Is this to be considered significant and just what does this mean in layman's terms? Thanks, Craig

Explanition of DMAX, which is what I think you mean by optical density :-)

For DMAX a jump from 4.2 to 4.8 is fairly significant, in both price and performance. If you really need it depends on what your intended use of the scans is.

It is primarily to be used to scan medium format transparencies (slide film) to be printed with a 32 bit printer.
