Photographing Rainbow Eyes By Using Birefringence
One of the many fascinating effects of cross-polarization is called “birefringence”, which is responsible for the psychedelic gradients in the seen here.
Use Polarized Lighting Techniques to Capture Cool Color Effects
Polarized light is light that has waves oscillating all in the same direction. There are two basic ways to get polarized light: from reflection or by using a filter.
How to Photograph the Power of a Punch Using Polarized Light
Many materials show internal stress when illuminated with polarized light and photographed with a second analyzing polarizer. This unique property of materials is called birefringence. Some of the more common material that exhibits this property is glass, ice, and most plastics.
