When using images as depth-map, or bump-map, or heightfield, or anything 
else that has nothing to do with a "picture" you'll have to make sure 
that there is at no point in the whole workflow any gamma correction 
applied - starting with the generation of the image itself.
Simply changing the gamma later is not what you want as this will throw 
away a lot of information and you will loose detail.

This has nothing to do with "abusing" gamma - this is just the way 
things do work and should be obvious after all this gamma correction 
talk in these NG.
