Red/purple polarizer
« on: August 17, 2012, 03:43:22 PM »

I recently purchased a set of GND filters, and the previous owner included a red/purple polarizer for free.  Aside from colouring the shadows and highlights (maybe B&W film?), are there any other uses for this filter? I can't seem to find any resources to explain its use. The closest I could find is the blue/yellow polarizer explanation on this site, but it isn't really applicable. I can post examples if needed.
