polarizing

These two images are from a test that I conducted with a cheap piece of polarized film, in order to test what I read in photography books about the benefits of using a polarizing filter.

 

I obtained my filter from a pair of paper 3D glasses that I got as a sample from the American Paper Optics company booth at Siggraph 2002 in San Antonio. I cut the glasses in half, and dissoved the paper with water, and then dissolved the glue with Elmer's "Sticky Out."

 

I held the filter in front of my tripod-mounted Vivitar 3 Megapixel, Fixed-focus, point and shoot camera. In one orientation the reflections from the glass on my poster are able to pass through, and obscure the photograph in the frame. In a different orientation the reflection is substantially subdued. The light blocked or absorbed by the polarizer never reaches the light meter built into the small digital camera, and it therefore automatically sets a longer exposure to compensate.

 

Like it? Would send me some bitcoin as a tip?
