The Cavision 5.65 x 5.65" Graduated Green Filter enhances reality, adding a touch of subtlety or drama to the image. This filter gives you the ability to add more "punch" to an otherwise ordinary scene.
Cavision Graduated filters give you the control you need to create a scene as opposed to just shooting a scene. With graduated filters, often it is necessary or desirable to balance the light intensity in one part of a scene with another. This is especially true in situations where you don't have total light control, as in bright contrasty landscapes.
Sometimes it is also desirable to add color to part of the photograph. For example, to add blue to only the sky. Cavision Color Graduated filters are half-color, half-clear, with a graduated transition for blending into the scene.
