I've never really understood the logic behind all that cr*p actually.
To my way of thinking, there is a unique correct way for a monitor to display a picture with a certain set of RGB parameters (for a fixed position of the monitor's twiddly knobs). Gamma corrections on a given platform are there to fix this, not to get creative with the settings.
The whole point of all this being that you should be able to save a picture on one system and have it look pretty much exactly the same on another. (And when this fails, at least one system has its gamma set wrong.)
Ian always claimed otherwise, but was never able to satisfactorily explain to me why not.
