The HOYA HRT circular polarizer filter allows up to 25% more light to pass through the polarizing film, giving the photographer approximately 1/3 more light than a standard circular polarizer. This new polarizing film is also used in the latest HD LCD televisions. UV ABSORBING The glass of the HOYA HRT filter also has UV absorbing properties, making the HRT a combined UV / circular polarizing filter. The most common use for a circular polarizer is to look for dark blue skies in outdoor photography. However, they can also reduce or eliminate reflections from nonmetallic surfaces such as glass and water. By rotating the outer ring, the filter can be seen through the viewfinder.
