Thanks. This is weird: I thought I would be looking for some kind of subtle
effect--but the banding your talking about really jumped out , once I
brought your image up in Photoshop and brightened it. Talk about not seeing
the forest for the trees! :-) If what I'm seeing is what you're talking
about, it looks like the (millions-of-colors?) render has somehow been
down-sampled to 256 colors or less. The effect looks just like a
digital-camera .jpeg image that I "reduced" to a .gif, to see what would
happen. Is it possible that your POV .png render is in a "reduced" color
pallette? Very odd. BTW, I couldn't duplicate your image's strange
appearance by changing my .jpeg to a .png, not even by invoking all the
"special" .png settings available in Photoshop. It still looked correct.
