Much of this very active interchange puzzles me, partly because I am a
photographer who is just beginning to learn some of the technical
details of digital work. I do realize that there are stages in the
processing of an image where visible artifacts are less likely to be
generated if you have a high-bit file. But if there were some way you
could get your printer actually to produce a grayscale with more than
256 discrete steps -- or even as many as 128 steps-- I would like to
know what isthe basis (with citations, please) that any of the
participants in this discussion have for believing that that your vision
could distinguish that many? I have not been able to get an answer to
this question from some experts in the physiology of visual perception,
etc., and of course I know it would depend on level of illumination,
fatigue, and other factors, but I have the impression that even the
trained, expert eye in the best of circumstances can reliably detect
somewhat less than 100. I cant cite any authoritative source for that,
and I would be eager to be corrected if I am mistaken (though I realize
this may not be the central point of the current discussion).
Thanks for illuminating me -- Lee Hershenson
