Blending Normal Maps
polycounter lvl 18
I've seen several different techniques for blending / overlaying normal map details in Photoshop and was wondering what technique most people are using.
Some of the techniques I know of:
1) Set the top layer to "hard light"
2) Set the top layer to "overlay" and set the blue channel level info to "128"
3) Blend each of the RGB channels separately and merge them back together.
Any others?

#2 is a bit different... activate the blue channel, Levels: Output Levels 2nd slider = 127 (range is 0-255 not 256), set layer to Overlay, then be sure to Normalize when done. Ben Cloward explains why (2d blend not 3d).
