Hi all,

What's the best way to tweak B/W images inside a shader setup?

I'm looking for something like a ‘change range’ remap node or something alike the PS ‘levels’ node.
So you can move the black/mid/white points around. I found the ramp node, but it's not entire doing what I need, especially in the mid tones.

cheers!

OK, a ‘change range’ or ‘aiRange’ is a ‘Fit Range’ in H. Check..

But I cannot find anything that would allow me to tweak the black/white or mid level of an image though…
Oh, and isn't there a simple ‘gamma’ node that I can plugin in between color slots?

rob

for gamma, you can use a color correct node or a power function node. A pow() exponenent is the inverse of gamma value.

To reply a bit late..

I kinda forgot all this stuff in in /img, instead of to be found in /mat <insert rolling eyes>

Only thing to figure out last is how to get the result of a comp tree into /mat as a texture.

cheers!
