The B+W 72MM REDHANCER SC (491) , made from didymium glass, is a filter with very special transmission characteristics. Designed to strengthen the reddish components of orange, near red or brown subjects, it is very popular for use in nature and landscape photography. It is particularly effective in conjunction with a polarizing filter, controlling a potentially bluish-gray veil and for increasing color saturation, e.g. to capture fabulously vivid scenery during the colorful autumn season. The use of color reversal film is recommended, because the automatic correction applied by printers to color negatives can erroneously interpret the desired effect as a color cast and reduce it by filtering it out.

This filter uses our standard B+W F-Pro filter mount, which has a front accessory thread and is made of brass. Compared to the earlier standard mount introduced in 2001, the F-Pro mount has become thinner. Now it can be used with wide angle lenses, including most 24mm focal lengths on a full frame body, without vignetting. Another advantage of the F-Pro mount is it's modified retaining ring, which is no longer threaded in from the front, but holds the filter glass in place from the back. When removing a filter or lens hood that has been screwed on too tight to the filter, the retaining ring is not at risk of loosening.

Each glass surface is vacuum coated with one layer of Anti-Reflection coating. This single layer helps to prevent internal ghosting and reflections. It also improves light transmission from approximately 92% (uncoated glass) to over 98%.
