Ie., using an SLR, turn the filter until you like what you see. Using a polarizer on an M Leica is possible, but best tried after you have some familiarity with a polarizer on a similar focal length on an SLR. I use polarizers on all lenses that will accept them at times, including 15 & 21 on 35mm, and lenses with similar angles of view on other formats. The only truly problematic lens/cameras are the rotating lens cameras. There I never use polarizers. * Henning J.
