channels in the gamut :O)


From photoshop help :

"About out-of-gamut colors

A gamut is the range of colors that a color system can display or print. A color that can be displayed in RGB may be out of gamut, and therefore unprintable, for your CMYK setting.

Photoshop automatically brings all colors into gamut when you convert an RGB image to CMYK. But you might want to identify the out-of-gamut colors in an image or correct them manually before converting to CMYK. "

Just convert into CYMK colors and all colors are in gamut :-), out of gamut warning disappear in photoshop...

So, "out of gamut warning" is linked to the proof settings, ie it's important for printing. Photoshop simulates the proof and, with the "out of gamut" warning, shows the colors that are out of gamut in these particular proof settings. Change the proof settings and the "out of gamut" warning differs.

For web display, it seems to be not relevant because monitor computer display RGB, which is the same color filter than the camera takes. To test it, just change the proof settings in photoshop to sRGB profile, and the out of gamut warning disappear!

Anyway, thanks to make me learn about gamut. It's always intersting and useful to learn new technical things.
