I created some BumpH image for a texture by simply converting the original texture to grayscale then renaming to bumph. My question though: after converting to grayscale are there any processing rules (changing luminosity etc) which would give the best results (or i just have to experiment by trial and error)? (for who doesn't know, The bumpH texture adds sort of 3D illusion to the original "flat" colored texture)
