The Formatt 138mm Graduated Chocolate 3 Filter is one of the most widely used category of filters. They enhance reality, adding a touch of subtlety or drama to the image.
This filter adds a deep, rich, warm dark brown tint to the image. It contains more magenta than sepia.
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. Formatt Color Graduated filters are half-color, half-clear, with a graduated transition for blending into the scene. They are available in an array of colors. Soft/hard indicates the degree of transition.
