The Tiffen 4 x 5.65" Gold Diffusion/FX 1/2 filter diffuses bright light entering the lens and produces a luminous effect.

Although the resulting image appears softer and more ethereal, there is little loss of sharpness or detail.

This filter works by diffusing the light entering the lens with small aberrations; by distributing the light more evenly, it creates a soft glow rather than a sharp, well-defined image as when shooting without a filter. In addition to the diffusion provided, a golden tint is also added to the image, bringing more warmth and helping to balance skin tones. Density 1/2 provides more softening than 1/4, but less than 1.

Tiffen filters are manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and polishing it flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5 mm.

The diffusion filter gives photographs an ethereal quality, creating a dreamlike atmosphere.

The soft image quality does not compromise overall image detail.
