Tiffen 67R29 67mm #29 Red Filter

The Tiffen 67R29 is a deep red contrast filter designed primarily for black-and-white photography, where it dramatically alters tonal relationships by blocking most blue and green wavelengths while freely passing red light. In practical terms, this means blue skies render almost black, green foliage darkens noticeably, and anything red or warm-toned becomes much lighter in the final monochrome image. The effect produces powerful, high-contrast landscapes, architectural shots, and scientific documentation that are difficult to replicate in post-processing alone.

Built using Tiffen's ColorCore technology — a process that laminates the filter dye between two layers of optical glass — the #29 filter delivers consistent color density edge to edge and resists fading or color shifts over time. With a filter factor of 16.5 requiring approximately 4 1/3 stops of additional exposure, photographers need to plan for slower shutter speeds or wider apertures, making a tripod advisable in many situations. Beyond traditional black-and-white work, the filter also transmits near-infrared wavelengths, allowing it to double as an affordable entry point for infrared photography when paired with an IR-sensitive camera body or film stock.
