- It still bands because either a 24-bit palette is not enough,
- you have more than 256,000 colors (really unlikely considering
- the resolution you're rendering at), or both. You're also
- assuming that your color gradations act like HAM.
-
- The best thing to do is to pick some kind of dithering scheme
- that you are pleased with and stand far away from the monitor 1/2 :-).
- Another thing you could do -- I'm guessing here at what you're trying
- to render -- is to reduce the harshness of your lights (if you
- have dramatic lighting or some other really high-contrast thing). This
- is usually the main cause of banding on my renderings even when
- viewed on a true 24-bit display (SGI).
-
- Or get an SGI Reality Engine (36-bits) :-).
