Colored Diffuser Filters control bright lights & surround your subject with a soft & gentle atmosphere, bringing a gentle & romantic atmosphere to your photos. The COKIN Colored Diffuser Filter consists of a set of two metallised films whose warm or cool colors vary infinitely, like a kaleidoscope, according to their position & the ambient lighting. They create a sustained diffusion which controls contours & contrasts, as well as a harmonious explosion of super-imposed colours. This lends an unreal luminosity to landscapes & still life work. Best results are obtained with three-quarter front lighting, taking care to curve the filter slightly in the direction of the subject. The more the filters are "wrinkled", the more intense the diffusion will be. The Cokin Coloured Diffuser Filters can be adapted to all focal lengths & diaphragms between f/2.8 & f/11.
