Overview

The B+W 39mm Basic Black & White Light Red MRC 090M Glass Filter is a specialized tool for photographers who shoot in black and white and want greater control over tonal rendering. By filtering out blue wavelengths, the light red filter darkens skies, enhances cloud definition, and increases overall contrast in monochrome images. It can also simulate moonlight effects and add a dramatic quality to landscapes and architectural shots that flat lighting would otherwise diminish.

Built with optical glass and a brass knurled mount, this filter is engineered for durability and precision. The Multi-Resistant Coating on both surfaces reduces reflections, flare, and ghosting, which is particularly valuable when shooting in challenging lighting conditions. Rated for use down to 24mm on full-frame sensors, the filter maintains edge-to-edge sharpness without introducing vignetting on moderately wide lenses. At just 0.96 ounces, it adds virtually no weight to your setup while delivering a meaningful creative impact on your black-and-white work.

Frequently Asked Questions

The Multi-Resistant Coating minimizes flare and ghosting caused by stray light, helping maintain image sharpness and contrast even when shooting toward bright light sources.
This filter excels at black-and-white photography, where it darkens blue skies for dramatic cloud contrast, simulates moonlight effects, and enhances tonal separation between subjects.
B+W rates this filter as suitable for focal lengths down to 24mm on full-frame format, so it should not cause vignetting at or above that focal length.
The mount is made of brass with a black knurled finish, providing a secure grip and resistance to cross-threading compared to aluminum or plastic mounts.
It is specifically designed for black-and-white work. When used on a color image, it will introduce a strong red color cast, which is generally undesirable for standard color photography.
