To enable slow shutter speeds to be used, especially with high speed ISOs, to record movement in subjects such as waterfalls, clouds, or cars To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure Tiffen's ColorCore glass is sealed between two optical glass sheets. In this way, Tiffen can better control the various densities of this filter and thereby create more exact degrees of filtration Top Hollywood motion picture studios rely on Tiffen filter for that multimillion-dollar productions Superior quality and design make Tiffen the overwhelming choice of moviemakers, professional photographers and even NASA
