display. Another effect of B+W polarizing filters is the reduction of reflections on non-metallic surfaces such as water, shop windows, paint. Objects behind it, even lettering behind reflective varnish, become recognizable again - a fascinating image enhancement without image processing. B+W polarization filters are circular polarization filters that take into account the different measurement systems of the 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 avoids false exposures.
