Cokin diffuser & pastel filters bring a gentle & romantic atmosphere to your photos. They allow a more gentle & subtle interpretation of your subjects, far removed from aggressive lighting, bright colour, & the opposition of contrasts. Diffuser & pastel filters may be used to soften, control, diminish, or blur. The COKIN Colored Diffuser Filter consists of a set of two metallized 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 colors. This lends an unreal luminosity to landscapes & still life work.
