Tiffen 4611G1 46mm Green 11 B&W Contrast Filter

The Tiffen 4611G1 is a 46mm Green 11 contrast filter designed for black-and-white film and digital monochrome photography. Green filters occupy a useful middle ground in the B&W filter spectrum: they lighten green foliage so that leaves and grass show texture and tonal variation rather than rendering as flat dark masses, while simultaneously providing pleasing, natural-looking skin tones in portraits. Compared to a yellow filter, the green offers stronger foliage separation; compared to an orange or red, it produces a subtler, less dramatic sky-darkening effect that suits scenes where you want contrast without heavy stylization.

Built using Tiffen's ColorCore process, the filter consists of the green filtration material laminated between two layers of optical glass. This construction method ensures the color is perfectly uniform across the entire surface — no hot spots, no uneven density — and protects the dye layer from scratches, cleaning damage, and UV degradation over time. The filter factor of 4 (two stops) is predictable enough for consistent metering, whether you're shooting on a manual film camera or using exposure compensation on a digital body. At 46mm, it threads directly onto lenses with that filter size and adds negligible weight or length to the setup.
