hep cyrille thanks for this hint - though it's my first time using shader - i tweaked around a bit with the example. i changed color saturation towards muchocolore in the texture.frag file. although removing color to get a black & white image i'm also loosing opacity f.e. with color = color* 0.1; the image gets almost black. where aside the green behind my ears can i find infos about how to handle the shader? thanks&salutis olsen

use shader! you'll have to make your own shader, but adjusting color saturation is quite easy. see gem documentation/10.glsl/01.simple_texture

hi roman & me are working on an videoinstallation using gem - only an additional [pix_contrast] in the gem chain hits the processing limit of our computer - is there a way to adjust color saturation in the gpu instead of the cpu in Gem? thanks&greets olsen
