With it, colours appear much richer and more luminous. Thus a blue sky appears darker, while white clouds clearly stand out from it. This effect is particularly clear at an angle of 90 degrees to the sun. This effect is also achieved with Blattwerk photography: the colours appear much richer and stronger. Disturbing reflections on water surfaces or window glass as well as gloss on non-metallic surfaces are reduced. Excellent workmanship The circular polarizing filter has excellent optical properties. The high-quality glass lens is embedded in a precisely manufactured metal frame. The filter has an additional internal thread, so that additional filters can be used. With a height of only approx. 7mm it is particularly thin, light and compact. It is transported in a protective cover that protects the filter from harmful UV radiation and thus significantly increases its service life.
