DIFFUSER FILTERS These filters use an exclusive COKIN process created by its founder and kept carefully secret ever since in the company laboratories. It's the way they diffuse the light from the luminous points of the image that gives shots that characteristic aspect. Copied numerous times but never equaled, the diffuser filters exist in 4 intensities, from the most subtle to the most marked. Thereis nothing else like them on the market. The Diffuser Light (820) is best for landscape photography and intimate portraiture. There is no equal for reducing facial wrinkles and small imperfections of the skin and is almost unperceivable. With the Diffuser 1 (830) and especially the Diffuser 2 (840), you can literally make the years melt away as if by magic,leaving behind only radiance and glow. As for nature shots, they will have a completely different dimension!

The Diffuser 3 (850) offers such a great diffusing potential that it virtually transforms itself into a shower
