Tiffen 55R29 55mm Red #29 Filter for Black & White Photography

The Tiffen 55mm #29 Dark Red Filter is a specialized optical accessory that excels at transforming black and white photographs with heightened contrast and rich tonal separation. By strongly absorbing blue and green wavelengths while freely passing red light, it renders blue skies nearly black, makes clouds and light-toned subjects pop, and creates a dramatic visual separation between elements that might otherwise appear as similar shades of gray. This makes it an essential tool for landscape photographers shooting in monochrome, as well as for forensic and scientific imaging applications where tonal differentiation is critical.

Built using Tiffen's ColorCore technology, the filter material is sandwiched between two layers of optical glass rather than applied as a surface coating. This laminated construction protects the filtering layer from scratches, moisture, and degradation over time, while maintaining consistent optical performance. The filter threads onto any 55mm lens and is also well-suited for infrared photography, where its deep red transmission characteristics help block visible light. With a filter factor of 16.5 requiring approximately 4 1/3 stops of additional exposure, it is best used in bright conditions or with a sturdy tripod to accommodate longer shutter speeds.
