Sounds right but when doing these kind of composites the source
images must not be gamma corrected. POV-Ray outputs linear samples
(not corrected) when assumed_gamma is not set. Gamma is applied
to the final composite. The reason for this is that
(a+b)^c != a^c+b^c.
Default radiosity brightness is the correct one so no need to
touch that.
So, Gimp has additive layer mode which is missing in Photoshop.
If the new version runs longer than 5 minutes without crashing
I'm going to find out if it can do gamma preview :)
The Hollywood Gimp would be ideal for this kind of work but there
is no windows version.
