The maximum polarization effect is achieved in landscape photography when shooting at an angle of 90° to the sun. For an even effect in the picture, and because of uneven skylight polarization, your focal length should not be less than 28 mm in 35 mm format.

Radiant white clouds against a deep blue sky or the deep colors of fall foliage don't happen by chance. B+W polarizing filters (polarizers for short) augment the purity of the intrinsic colors and increase color saturation and are among the most important filters for analog and digital photography.

Generally speaking, with the help of a properly oriented polarizer, reflections can be completely suppressed in an ideal situation. Here, the ideal situation means that the lighting and shooting angles are almost the same and correspond to the angle of maximum polarization, usually 30° to 40°.

B+W polarizing filters are circular polarizers which are compatible with nearly all modern cameras when beam splitters are used in the light path for TTL exposure metering or autofocus. Exposure errors are therefore avoided. The multiplying factor with HTC is 2 to 3, which is equivalent to 1 to 1.5 f-stops. Other polarizers up to approx. 3 stops. Often regarded as the most important filter for photography.

Because the filter mounts rotate, the polarization effect can be visibly controlled in the viewfinder or on the monitor display. Another effect of the B+W polarizer is to reduce reflections from non-metallic surfaces such as water, glass, and glossy paint. Objects and people behind surfaces such as shop windows and car windshields become visible again – a fascinating image enhancement without image processing!
