I believe I read somewhere that using polarizers can cause colors when shooting crystals. I don't know if the polarizers go on the light sources, on the camera, or both.
I tried a polarizer on the lens, but it really did nothing. I know that there are color-enhancing polarizers that add slick colors to sunsets etc, but I've never tried one of those.
The Rasmussen shots in particular look like two very carefully blended light colors are coming together, but my attempts at doing that resulted in one effective blended light. Maybe ROb's idea about LED's would let me focus the sources better.
