The absolute clarity of the glass combined with advanced polarizing material make True-Pol filters particularly useful on demanding scenes, like shooting through windshields in rigged vehicles.
Polarizers are commonly used to control glare on water and to allow the camera to see below the surface. They are also used to reduce glare on car bumpers and control reflections on plate-glass windows. Polarizers are so versatile they can also perform the opposite functions.
Cinematographers report that True-Pol filters capture more color saturation, wider tonal range and greater contrast.
