The Formatt 3 x 3" Graduated Coral 7 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.
Coral Filters can be considered as both Color Correction and Color Effects Filters and are used to warm up cool lighting situations such as overcast days.
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.
