The Cokin Yellow / Green filter can be used with a Digital camera or Film camera using Black & White film. The Digital camera can be used in either colour or Black & White mode. For Black & White mode, set the menu to the "B&W" position & then use it like a film camera. The Yellow / Green colour filter is great for outdoor photographs or indoor portraits under tungsten light. It improves skin tones & emphasises the feeling of liveliness. Also recommended for shooting landscapes where the Yellow / Green colour filter will improve the contrasts between the sky & clouds.
