Hello All:
I thought I might share this. I am running into the limits of 8-bit RGB displays all the time now. I'm not sure when I got so picky, perhaps after properly calibrating my monitors with ICM profiles. In any case banding even at 255 levels of intensity for each of R, G, and B is now very apparent to me.
Upon reflection I realized there is not much that can be done for 24-bit images BUT if one has 16 or 32 bits per channel banding can be reduced with dithering.
FSDither script is a simple little script that takes an image (ideally one of more than 8bits per channel) and performs Floyd Steinberg dithering and generates a new image at 8bits per channel.
Arguably after performing this dithering you should be able to see more of the actual shades present in a 16 or 32 bit image on your 8-bit (per channel) monitor.
Enjoy!
Colin
