B+W Basic 091 MRC Red Dark 630nm Filter

The #590/090 Red Light MRC Basic Filter from B+W can be used to increase image contrast when using black-and-white film. When using this filter, green and blue subjects are reproduced in darker shades of gray than if a filter was not used. Simultaneously, yellow, orange, and red subjects are rendered in lighter shades of gray. Landscape photos show greatly enhanced views into the distance and higher tonal separation in photos of objects that are blue and green render very dark. When shooting landscapes, shades of green foliage can be more differentiated, and this filter can also minimize the haze caused by the bluish cast of daylight.

B+W MRC Basic filters are made with the exclusive Multi-Resistant Coating (MRC) nano premium coating technology. This high-quality broadband coating is applied on both sides and enhances the optical imaging properties, allowing uniform and increased transmittance across the entire light spectrum to be achieved, with minimal physically induced remaining reflection. The nano all-around protection on the filter glass also ensures increased scratch resistance and extremely fast, easy cleaning, providing a long filter life. The slim filter ring design is compatible with wide-angle lenses with an equivalent width of a 17mm full-frame lens. The top knurling is redesigned for enhanced gripping.
