Designed with filmmakers in mind, this 4 x 5.65" Black Satin Diffusion Filter (1/4, 1/8) from Tiffen features a low density for an understated effect. It is designed to subtly soften the image and lower detail resolution, being often sought after by videographers who want to simulate the look of film footage while shooting on digital gear. The filter is made of water white glass and can be mounted on compatible square filter holders. This black satin model has a grittier look than a regular satin, and gently controls highlights while reducing overall image contrast. It can smooth out unwanted blemishes, wrinkles, or other fine details in a subject's face while keeping the general image in focus, making it ideal for portraiture work. Manufactured using ColorCore technology, each Tiffen filter is designed to be accurate in its effect and produce consistent results.Subtly Lowers Detail ResolutionSmooths Out Blemishes and WrinklesReduces Contrast and Controls HighlightsColorCore TechnologyGlass ConstructionThe Tiffen 4 x 5.65" Black Satin Filter (1/2, 2, 3) can be applied to purposely reduce the appearance of blemishes and wrinkles while providing an intentional warming effect with granularity over an entire image. This can be useful for creating a more flattering result of a subject while highlights are softened, contrast is reduced, and textures are given a smoother appearance. Additionally, halations around highlights are created which can further enhance a subject's appearance or produce a desired effect while overall sharpness is maintained.This filter has a grade of 2. Grades of 1/8, 1/4, 1/2, 2 and 3 are also available where this filter type's effect becomes approximately twice as strong with each grade number increase.This filter is constructed from water white glass for increased clarity as well as color fidelity.
