The Photron Slim CIR-PL filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc.
This Photron filter gives you total "on location" control of color saturation, make skies bluer, grass greener-even eliminate surface reflections from glass and water - all with picture perfect results.
The filters are all double-threaded, so you can stack your lens cap and other accessories as needed.
Light rays which are reflected by any surface can become polarized so polarizing filters are used to select which light rays enter your camera lens.
They also enable colors to become more saturated and appear clearer with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds.
A poorly made filter makes a great lens and camera worthless, that's why the our frame rings are constructed of special alloys that won't expand or contract over time.
Photron’s polarizing filters do not affect the overall color balance of a shot and ensure consistent color and accuracy throughout the entire surface of the glass.
Ultra slim low profile frame, helps to avoid vignetting
Frame/Mount rotates to control amount of effect.
