Tiffen 6785C 67mm 85C Color Conversion Filter

The Tiffen 6785C is a 67mm color conversion filter in the 85 series, specifically designed to correct the color shift that occurs when tungsten-balanced film is exposed under daylight conditions. Without correction, tungsten film shot in daylight produces an unnatural blue cast. The 85C counteracts this by applying a light amber tone, though its effect is deliberately cooler and more restrained than the 85 or 85B variants. This makes it the right choice when only a partial correction is desired, or when the ambient lighting is a mix of tungsten and daylight sources.

Beyond its corrective function, the 85C can serve as a creative tool. When mounted on a lens while shooting daylight-balanced film in daylight, it introduces a subtle warm tone across the image, lending scenes a slightly golden quality without the heavy-handed look of stronger warming filters. The filter threads onto any lens with a standard 67mm front diameter and is built with Tiffen's optical-grade glass to preserve sharpness and minimize flare. For photographers who work with film and need precise, physical control over color temperature at the point of capture, the 85C fills a specific and useful niche in the filter kit.
