With the Cokin Filter P004 Green filter you create certain grey tones that are normally not obtainable with black and white photography. These grey tones add depth to your images. When you use the P004 Green filter for portrait photography, the skin and the lips get a slightly darker tint.
Cokin filters
The Cokin colour filters can be used with the P Holder system. You can use different colour filters at the same time in the P Holder system. The filters are flat and square, so they don't take up a lot of space and will always find a place in your equipment. As an optional accessory you will find the Cokin P Holder system, together with mounting rings for different lens sizes.
