Circular Polarizer filters are used to reduce reflections from non-metallic surfaces (windows, water and so on) and increase density within the sky and/or foliage by absorbing reflected light. They also allow to emphasize details such as clouds and makes pictures crisper, with deeper color tones. Their effect cannot be achieved with a computer software.

CIR-PL filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. 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.
