In photography and videography, a filter is a camera accessory consisting of an optical filter that can be inserted in the optical path.
(Lens Filters) Attached to the end of the lens to achieve certain filter effects.
A polarizer is a device that converts a beam of electromagnetic waves (light) of undefined or mixed polarization into a beam with well-defined polarization. The common types of polarizers are linear polarizers and circular polarizers.
A light filter which only allows light waves of a certain rotation through. Polarized material with perpendicular filtering is used in LCDs to enclose the liquid crystal.
A stretched polymer which transmits light in only one axis. A typical display has polarizers on the front and back.
Circular Polarizer - Light & sun rays which are reflected become polarized. Circular polarizing filters zero in on which light rays enter your cameras lens. They then remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and the LCD screen and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. Circular polarizing filters do not affect the overall color balance of a shot. Includes a 1 Year Warranty.
