Tiffen 4.5" Round Black Diffusion/FX 1/4 Filter
Key Features
  • Diffusion Filter Creates Glow Effect
  • Softens Skin and Blemishes
  • Slight Reduction in Contrast
  • ColorCore Technology
The Tiffen 4.5" Round Black Diffusion/FX 1/4 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 1/4 density, providing the least amount of softening.

Tiffen Black Diffusion FX Overview

The Tiffen 4.5" Round Black Diffusion/FX 1/4 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 1/4 density, providing the least amount of softening.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch.

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.

Does this filter contaminates the bokeh balls with black spots or something else related to the diffusion filter?
Asked by: José Andrés
You will see black dots on highlights when you are shooting at a deep F-Stop. If you're shooting at a shallow DOF you wont see any of the dots.
