I am working on a POV-Ray project which involves loading an external image
and re-displaying it with no color adjustment. I recently discovered that
"ambient 1" with no light_sources is not enough; the picture comes out
brighter than the original. I traced the problem to the picture below. The
top band is POV-Ray's rendering of a smooth gradient black to white at
ambient 1 with no light_sources. The bottom band is an unmodified gradient
black to white made by Fireworks. I hold in doubt neither gradient, and I
think the problem lies in how the object color is transformed into a final
pixel color. What is going on, and how can I disable or counter this
change?
