I use my P4P mainly to shoot video. I recently purchased polarpro's Artisan Collection which comes with ND32/PL, ND64/PL and ND128/PL. I was reading somewhere on the internet about rotating the filter to get the best results and i don;'t know what that means ecaxtly. Question i am asking did i waste my money purchasing polarized filters when i should have purchased standard features? Can i use polarized filters to shoot video or are polarized filters made for photos only?
