B+W Filter 82mm KR1.5 Overview
This filter also blocks UV radiation, however it also has a delicate reddish-yellow tone designed to counter-act the high blue cast in the shadow portions of color photographs caused by light coming from a blue sky. It produces a warmer image tone and reduces the haze in distant scenes. The exposure factor
amounts to only ¡.¡, so for practical purposes it can be ignored. Because of its very faint color, a Skylight
Filter can be kept on a lens constantly for protection, as long as a slightly warmer color rendition is desired, as it would be with color reversal films that tend to produce cooler colors.
