Steve A brilliant article if a bit too scientific (I had to read it several times but I now, at least, understand color theory and the need for color management). However, I would like to take issue with the following: To have color you need 1) light, 2) an object and 3) an observer - for our purposes, a human observer. Without all these components you do not have color. This is an old worn, torn argument often used by color management gurus to justify their huge fees and it just does not hold water. It's like saying, when I die, existence comes to an end. Of course it does - for you! For the rest, it carries on, erm, existing. So, colors exist, even without an observer. If you don't believe me, try this little experiment: walk into a garden or a park, stand infront of a flower bed in bloom (preferably a bed of sweet peas but almost any variety will do), close your eyes and ask a passer by (preferably a digital photographer versed in color theory - well, maybe not such a good idea, just find a passer by - to see if the flowers have turned to monochrome). If they faint, you know your theory holds water. If they say "Yeah, pull the other one" and walk on, you know your theory is leaky. But take my word for it, it's about as sound as a MacDonald's burger is environmentally friendly! BTW, where can I buy your Toast Guide�? I just cannot get my wife to reproduce the toast the way I like it, and consistently. I think the Toast Guide� would be the ideal solution for solving the problem. I have looked in depth at the ToastiChrom� profiling kit but it is way out of my budget.
