Photographic Images and Optical Effects Using Birefringent Materials

The author reveals a method of producing colorful abstract photographic prints using polarized light and simple materials such as cellophane. Until recently the use of birefringent materials and polarization had been limited to the production of light shows or light boxes with ever-changing patterns. This paper explains how permanent prints can be made using positive-to-positive photographic print papers and a modified enlarger. Methods for producing optical displays and special effects for television using birefringence are also discussed.
