B+W XS-Pro Digital HTC KSM MRC nano

Polarizing filters are among the most important filters in both analog and digital photography. Since they are rotatable in their mount, the effect of light suppression can be visibly adjusted in the viewfinder or on the display. Another effect of B+W polarizing filters is the reduction of reflections on non-metallic surfaces such as water, shop windows, or paint. Objects behind these surfaces, including text behind reflective paint, become visible again – a fascinating image enhancement without the need for post-processing. B+W polarizing filters are circular polarizers that take into account the different measurement systems of cameras. This is the case with almost all modern cameras when beam splitters are involved in the TTL exposure meter or autofocus beam path. This helps to avoid incorrect exposures.
