Very good examples (starting with the prolog) and a simple language that makes it easy to understand such a weird and complicated topic. Thank you so much!

This writeup on color space is the best I've come across yet: plain words, yet great depth of perception, that only a true expert (and capable teacher) can get across. I particularly appreciated the section on 'non-linear encoding' that made a difficult concept easy to comprehend. You ought to write a book with all the material you have published.

You don't mention bit depth, but it's an important factor isn't it? The width vs. precision tradeoff is really only relevant for 8 bit images. A 16 bit image contains so much information per pixel (65,000 levels vs. 256 levels in 8 bit images) that even the widest photo color spaces get plenty of precision. So, if you stay in 16 bit precision while editing, there is really no reason to use a limited color space, like sRGB. You'd preserve more image information by using Adobe RGB. Or maybe even ProPhoto RGB? Correct me if I'm wrong :) Great blog you have here, btw! Cheers, Martin Interesting read!
