Color Space Color Gradations
In reply to Great Bustard, Apr 29, 2013

You mean which color space makes better use of the available bits with histograms such as these (sRGB to the left, ProPhoto to the right)?

As far as I know, any issues that ProPhoto had with posterization went away when PS switched to 16 bits, so I would guess that if there is an advantage to the higher color resolution of the smaller space it is not noticeable in practice.
