Download the Gimp Normal Map plug-in from http://code.google.com/p/gimp-normalmap/
Gimp plug-in does just as good as the Normal Map filter in Photoshop.
Download the zip file for your computer (32 or 64 bit).
Unzip the file. Copy and paste the normalmap.exe file to your Gimp Plug-ins folder. In this case it was: C:\ Program Files\ GIMP 2 \ lib \ gimp \ 2.0 \ plug-ins.
Go back and copy and paste the three .dll files to your Gimp bin folder.
In this case it was C:\ Program Files \ GIMP 2 \ bin. Copy and paste all three.
To use the Normal Map plug-in in Gimp, you must have a grey scale image (first pick a Layer or Flatten Image). Then go to Filters / Map / Normalmap.
The most useful settings with this Gimp plug-in are the Filter and Scale.
Click OK to convert the grayscale image or layer into a Normal Map. You
have to experiment with the settings. If the results are too soft, or
to deep, then Undo, and change the settings again.
In Gimp, the grey scale image is converted into a Normal Map.
The Normal map is applied. See the Normal Map tutorial. See the cool video of the ball turret.
