Don't forget about aliasing as well.  A simple approach to removing
aliasing from your synthesized images is to "supersample" the scene
and downfilter the supersampled image to the desired resolution.  This
is how many high-performance anti-aliasing hardware works -- by
supersampling.

Sampling theory indicates that you should increase the resolution by at
least a factor of two.

Also, don't forget that if you're rendering for video the color gamuts
of RGB monitors and NTSC are not the same.  Make sure your colors fit
inside the NTSC gamut and that they are still distinguishable in NTSC
space if they need to be visually different..
