Hi, I was wondering is there any way to dynamically vary contrast with pen pressure in Photoshop? What I'm saying is, is it possible to apply contrast to an existing image via the brush in this way? I think that would be useful for working with heightmaps and greyscales in Photoshop. Perhaps, paint in greys on a layer with the blend mode set to a suitable mode might be one of doing it. Anyone ever tried something like this?
