This polarizer filter is used to increase color saturation, darken blue skies so white clouds

stand out, and eliminate reflections from nonmetallic surfaces like glass or water. It will also reduce

the softness in scenery caused by atmospheric haze. This filter will not change the overall color balance of

a photograph. Most modern SLR cameras use a polarizing half mirror (split beam metering) system and the circular

PL is designed to be used with them. Filter Factor: 3~4 or 1 2/3 to 2 stops
