Thanks Rob, that was the source of confusion, and why I saw no visible change.
I stand corrected Shaf.
I find that Photoshop is quite capable of buggering up a perfectly good file
at a single mouse click.
(Which is why I haven't experimented much with profile-to-profile)
Most of the profile changes simply seem to be gamma changes or simple hue
shifts, and I can see the point of those, apart from "wide gamut RGB" which
seems to do the equivalent of desaturating the image colour by 40%.
Excuse what might be a daft question, but what device exists that displays
such a file correctly?
And why would anyone want to create files that can only be displayed on such a
device?
Also, how come the existing white point stays constant if the colour space is
supposedly expanded?
Surely white should be 'desaturated' too, down to grey.
Sorry, but the only way that I can see of changing my 'real' colour space, is
to waggle the contrast on my monitor up and down, and/or change the type of
paper and ink in my printer.
Regards, Pete.
