Cross Polarization of Plastic – Magic

I learned this way back at the beginning of my career, from a very technical photographer and one of the original Harmonicats – (goes back to the old Ed Sullivan Show days – look them up!).

This technique, I was told, is a way to check stress in plastic manufacturing. I adopted it as a creative tool.

The set up is a gel polarizing filter on a light box or light source. Position the plastic subject between your camera and the light. Add the polarizer filter on your lens and rotate until all the light from the source goes black. The light coming through the plastic gives you the magic swirls of color. I’ve used this on assignments as well as stock illustrations. ¬†Great unique look and you always get asked, How did you do that!
