Many techniques have been developed for diffusing or softening images, whether to create a mood in a landscape or portrait or simply as an aid to make people look glamorous. The Black Diffusion/FX Filters produce silky-smooth textures, even in tight close-ups without sacrificing image clarity. They offer the most advanced diffuser ever developed by Tiffen. Each creates a diffused image that doesn't look like it's been shot through a filter.
