Tiffen 49R25 Red Contrast Filter 49mm

The Tiffen 49R25 Red Contrast Filter is a staple tool for black-and-white film and digital photographers who want bold, dramatic results straight out of the camera. By absorbing blue and green light while passing red wavelengths, the #25 Red filter significantly darkens blue skies, making white clouds pop with striking contrast. It also reduces the effects of atmospheric haze and can simulate a moonlight look when used to underexpose daylit scenes.

Built with Tiffen's ColorCore technology, the filter element is sandwiched between two layers of optical glass rather than simply coated on the surface. This construction delivers uniform filtration across the frame and provides better resistance to scratching and environmental wear. At 49mm, the filter suits many popular compact primes and mirrorless kit lenses. Photographers should account for the filter factor of 8 — a 3-stop exposure increase — when composing shots, particularly in lower-light environments where shutter speed or ISO adjustments may be necessary.
