I got the polarized 2" squares from Edmund Optics and glued a triangular shaped piece over the lens of my Panda.
I sent #500# command messages to the camera to get before and after pictures taken under similar conditions at the same time of day.
Earlier one of you guys mentioned that a polarized lens had to be rotated to find the optimal orientation for reducing glare. I wrongly thought that was a bogus statement.
Today I received the polarized lens for a GoPro camera, and sure enough the video instructions show how to rotate the lens to determine the "up" position.http://www.polarprofilters.com/how-to/
I still have the remainder of the 2" square that I cut my Panda filter from, so I took it outside and looked at the glare coming off of my truck bumper as I rotated the scrap piece of lens material...I'll be darn, it does make a difference...so I'll need to peel off the filter that I put on my Panda and replace it with a filter that is properly oriented....however, the filter makes a huge difference even if it's not rotated to the best position.
