Tiffen 138mm Black Diffusion/FX 1 Filter

Tiffen Black Diffusion FX Overview The Tiffen 138mm Black Diffusion/FX 1 Filter diffuses strong light entering the lens and produces a glowing effect. While the resulting image appears softer and ethereal, there is little loss of clarity or detail. This filter works by diffusing the light entering the lens with small aberrations; by spreading the light more evenly, a soft glow is created rather than the sharp, well-defined image when shooting without a filter. This filter has a 1 density, providing a small amount of softening. Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings. Diffuser filter provides an ethereal quality to photographs, resulting in a dream-like atmosphere. Soft image quality does not detract from the overall detail of the image. Light entering the lens is diffused by small aberrations, creating a soft glow rather than the sharp, well-defined image when shooting without a filter.
