The HR Digital UV Blocking Filter, specially designed for digital photography, transmits visible light without hindrance while cutting out ultraviolet radiation. As this filter prevents the bluish cast and loss in contrast, its main application area is taking images of distance views.
Compared to the eye, the sensor is much more sensitive to UV radiation and therefore reproduces diffuse UV radiation as a bluish cast. UV blocking filters cut out UV radiation and create images characterized by richness of detail and colour fidelity. Especially in the high mountain regions and at the sea, the intensity of the UV radiation may be that strong that a UV blocking filter is needed. Its effect cannot be replaced by digital imaging software at a later date.
