Carry Speed CS021 - Camera filter

Polarizing filters work by cutting the amount of polarized, or reflected light, that reaches the digital sensor. Polarized light can be found everywhere, including reflections on the surface of water, glass, reflecting from the surface of leaves, and even reflect from the soft blue of the sky. Polarized light often makes objects appear shiny. The use of a polarizing filter can reduce this, and will help saturate the colors, particularly in landscapes that contain foliage and a vast blue sky. Polarizers are very important filters and will retain information during image capture that is normally lost and cannot be recovered in post processing.
