[QUOTE="Tony S, post: 428331, member: 20864"] Two polarised filters, one on the camera and one on the window. You will loose about 40% of light transmission but will get a clear picture. The filters have to be angled at 90° to each other. Only trial and error finds the best combined angle. Polarizing filters for cameras are easy to get, I’ll look for the manufacturer of the polarizing acetate sheet I used for photography Phil D may have a better idea. [/QUOTE]
