Tiffen 72R25 72mm #25 Red Contrast Filter

The Tiffen 72mm #25 Red Filter is a specialized tool for black-and-white photographers who want to push contrast to dramatic levels. By absorbing most blue and green wavelengths, it renders blue skies as deep, near-black tones while allowing clouds to remain bright — a striking effect that transforms ordinary landscape compositions. It also cuts through atmospheric haze and fog, producing cleaner images when shooting distant subjects. For infrared film shooters, the #25 red filter serves as an effective starting point for blocking visible light and emphasizing infrared wavelengths.

Built with Tiffen's ColorCore technology, the filter dye is sandwiched between two layers of optical glass, ensuring uniform color density from edge to edge and protecting the filtration layer from scratches, cleaning solvents, and humidity. The 72mm thread size fits directly onto compatible lenses with no adapter ring needed. The filter factor of 8 translates to a 3-stop exposure compensation, which TTL metering systems handle automatically. While the deep red color makes this filter unsuitable for standard color work, it remains an essential tool for anyone serious about high-contrast monochrome or infrared imagery.
