Details:
Believe it or not here in Iowa this winter I had only a few opportunities to take macro pictures of snowflakes. Instead I began experimenting with photographing ice crystals between polarizing filters. It was plenty cold for freezing water. For sure! I soon discovered that thin ice displays a stunning colorful birefringence - a phenomenon that was used to identify mineral grains in moon rocks. I developed a way to easily document the images using a cell phone. Basically you simply need to remove the polarizing filters from a pair of Real 3D glasses (used in theaters) and place one filter on each side of a thin layer of ice on glass. To learn about how I did it take a look at the website I just created: http://iowatom.weebly.com/
