The Formatt 3 x 3" Graduated Pink 1 Filter is one of the most widely used category of filters. It enhances reality, adding a touch of subtlety or drama to the image.
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.
This is a very striking pink giving a "bubblegum" color.
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.
