Hoya Linear Polarizer Polarising camera filter 46 mm

Polarizing filters simply cut through unwanted reflections from non-metallic surfaces such as water and glass in addition to light reflecting off moisture and pollution in the atmosphere. This results in bluer skies greener leaves reduced or eliminated reflections on glass and greater clarity in your final image. HOYA's polarizing filters do not affect the overall color balance of a shot.<br><br>How to select the correct Polarizing filter: PL (Linear Polarizing) and PL-CIR (Circular Polarizing) filters have nearly identical effects but it is important that you choose the correct version for your camera. Many of today's cameras use semi-silvered mirrors or prisms to split the light entering the viewfinder in order to calculate exposure and focusing distance. PL (Linear Polarizing) filters can sometimes interact with these items to give unpredictable exposure or focusing. So we recommend that you choose a PL-CIR filter unless you have a manual focus camera that has no beam splitter. <br><br>Linear polarizers are more effective in studio lighting situations where a polarizing gel has been placed over the main light source in order to remove reflections from a non-metalic surface such as water or glass.
