Hoya ringpolarisatsioon HRT 55mm (HOYA-PLCHRT55P)

Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. If you're out walking on a lovely day - in the mountains or at the beach - and you want to get a fabulous shot of a cloud-filled sky or make the water seem more saturated, then a polarizer is the way to go. This filter is the best way to make the clouds stand out, increase or decrease the saturation of the ocean or increase or decrease the reflection off the water. You can also use this filter when shooting into glass or windows since it will, again, either increase or decrease reflections. If you're shooting black and white and want to simulate a threatening storm, try throwing on a Red filter. The vista will take on the appearance of an imminent, ominous storm. Along with a UV or Skylight Filter, a polarizing filter should be a part of everyone's gear bag. It can turn a run-of-the-mill image into a stunning, creative photo by increasing color saturation. The Hoya HRT circular polarizing filter is unique in its design since it incorporates a High Rate Transmission film that permits more visible light to be passed through the filter while still producing the same degree of polarized light. This filter now permits the equivalent of 1/3 stop more light to be taken in yet it still filters the same amount of polarized light. This can be a huge benefit to users of both digital and HD technology cameras and lenses. This new polarizing film is also used in the latest HD LCD TVs. The glass of the Hoya HRT filter also has UV absorbing properties making the HRT a combination UV/circular polarizing filter. This filter eliminates ultraviolet rays to remove haze from outdoor shots as well as polarizing the light to remove reflections, and increase color saturation, without affecting the overall color balance Can dramatically enhance a blue sky and make the clouds more prominent Used best at right angle to the sun Effective with cameras that use beam splitters in the path of the TTL light meter and with AF cameras
