These filters have a clear spot in the center which has no filter effect. This means that the subject in the center of the picture is reproduced clearly while the surrounding area which is often distracting is changed, usually colored or darkened. The main area of use is for portraits. The transition from subject to background, and also the size of the clear circular area, depend on focal length and aperture. The transition is more gradual when the aperture is opened wider. The circle becomes larger as focal length is increased. The circle becomes larger and less clearly defined if the filter is placed further forward. The distance between your lens and the Center Spot filter can be varied by using the Cokin Modular Hood and a Coupling ring .

The Bicolor filters are not symmetrically colored, and different effects can be obtained with the same filter just by rotating the filter holder.
