Well, one of my first amiga programming projects (almost 2.5 years ago!)
involved displaying an image digitized by the Macintosh compatible
Thunderscan(R) digitizer. This device provides 5 bits/pixel, so I just
HAD to see the difference! I wrote the program so that you could use
command-line switches to display in low/high res, lace/nonlace, and
double/nondouble modes. The double is the aforementioned pixel level
dithering idea. I found one problem with it, tho. On my monitor, at least
one of the dithered grey levels hit the green phosphors in my monitor
more than the red+blue, which gave it a green 'tint'. I have a 1080 with
a minor corner focus problem.
