Tiffen 5547 55mm #47 Blue Filter

The Tiffen 55mm #47 Blue Filter is a deep blue color filter designed to impart a strong, saturated blue cast across your images. Originally developed for film photography workflows — particularly dye transfer printing and contrast manipulation — the #47 filter remains a useful creative tool for photographers who want to dramatically alter the mood and color palette of a scene. When mounted on a 55mm-threaded lens, it accentuates atmospheric elements like haze and fog, lending landscapes and outdoor scenes an ethereal, cool-toned quality.

Because the #47 is a dark-blue filter, it absorbs a substantial amount of light across the red and green portions of the spectrum. Photographers should plan for approximately 2-3 stops of exposure compensation when shooting with this filter attached. On digital cameras the effect is immediately visible in the viewfinder or on the LCD, making it easy to preview compositions before committing to a shot. While modern white balance and post-processing tools can replicate some color shifts digitally, the optical filtering provided by the #47 creates a uniform tint across the entire frame that is difficult to precisely duplicate in software, giving it continued relevance for photographers who prefer in-camera creative effects.
