Why circular polarizers?
7 months ago

I understand the principles of polarized light and circular and linear polarizers, but I don't understand why only circular polarizers are acceptable for digital cameras? I had a linear polarizer for my old film camera, and was flummoxed when told that I needed circular polarizers for my first digital cameras. Can anyone clarify this for me in a not-too-complicated way? Thanks, and please excuse my naivety.
