If you’ve never used a circular polarizer filter before, here’s an interesting video by Mitch Bergsma that shows the effect it has on various outdoor scenes. He mounted a B+W Polarizer filter onto a couple of lenses on his Canon 7D and filmed a number of landscape spots while turning the filter to see its effect as a gradual transition. Pay attention to the sky, leaves, and reflections.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
