CPL filters can also be used to saturate colors and to provide better contrast. The effect can be seen through the cameras viewfinder and changed by rotating the filter ring. The filter factor varies according to how the filter is rotated and its orientation to the sun or light source(approx. +1.3 stops). Typical applications include darkening skies, water reflection elimination and window / glass / eyeglass reflection elimination. CPL filters are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems). Each Filter comes with a hard protective storage case. Filter Measures: 88mm x 88mm Protective Case: 95mm x 113mm
