I was looking at polarization filters and there seemed to be at least two types (linear and circular), any specific suggestions? Whats the difference?
Linear only works in one orientation. Turn your camera 90 degrees and you essentially don't have a polarizing filter. If you put one polarizing filter over another in the same orientation, light still gets through. Turn one of them 90 degrees to the other and all light is blocked.
I have a polarizing filter that rotates. you can rotate it while looking through the lens to see how the glare is reduced. Sometimes glare is good though, depending what you are trying to do.
I've never used a circular polarizer, so can't comment on that. My guess is that if the glare is in a narrow strip in the vertical plane at the center of the image, it should work fine- but not so well on the far right or left of the image.
