I've done anaglyphs in PV~WAVE on both 24-bit and 8-bit color systems.
The 24-bit color approach is straight-forward, one image in red and the
other in green. It works best if you gamma correct or approximately
gamma correct via the lookup tables.

What was suprising is that 8-bit color is ~adequate for anaglyphs. You
have to redo the LUT for 4-bits red and 4-bits green and again it is best
to gamma correct at the same time. The secret is to histogram equalize
the original two images down to 4-bits each.
