Tiffen 55UC1 55mm Ultra Contrast Filter, Photo/Video

The Tiffen 55mm Ultra Contrast 1 filter is designed to reduce the contrast ratio in a scene by gently lifting shadow areas using the ambient light already present. Unlike diffusion or fog filters, it accomplishes this without softening the image, adding halation around highlights, or producing flare—making it a practical on-set tool for both photographers and cinematographers who need to retain detail in darker portions of the frame without resorting to additional fill lighting.

Constructed with Tiffen's ColorCore glass lamination process, the filter threads directly onto any 55mm lens and adds minimal bulk to the setup. The Grade 1 designation means this is the mildest strength available, well-suited for subtle correction in moderately contrasty scenes. For harsher lighting conditions, higher grades in the same series offer progressively stronger shadow fill. Because the effect is optical rather than digital, it integrates naturally into the captured image, saving time in post-production color grading.
