What that setting does is remove all color except from the one you choose (it gives you a small selection of non-removable colors to choose from). So whatever you shoot .. it pulls only the color you choose out and removes the color from all others.
I thought it was a cool setting, I happened on it by accident lol.
It's under the micros setting .. there should be several color adjust settings .. just fiddle with it (but make sure you remember what you did LOL .. so you can put it back after you're done ).
i have a sony cyber shot.. .dunno the manual is-- but all i have is a bunch of pictures.. dunno what they mean, but i dont remember ever seeing that setting...
i need a new camera, so i think im gonna search out that setting--- i love it!!!
