I'd like to generate a displacement map from a picture, a la crazybump, in photoshop, for specific tuning.
Do you guys know what algoritm is applied during this process ?
Pixplant and Shadermap do the same kind of treatment so I guess it's "basic"
Put appart the recognize shape option whis looks pretty complex.
Yet i fail to mimic it in photoshop. It's not a gaussian blur, it's like some sort of glow effect + highpass ?
I suspect it treats dark and light areas separatly.
Any ideas ?
