DESCRIPTION

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 dont have total light control, as in bright contrasty landscapes. Exposing for the foreground will produce a washed-out, over-exposed sky while exposing for the sky will leave the foreground dark and under-exposed. Grad ND filters are part clear, part neutral density. They allow the transition to be blended into the scene, often imperceptibly. Some Tiffen graduated filters are available with vertical/horizontal and soft/hard designations. Vertical means the graduation line runs across the short dimension of the filter. Horizontal means the graduation line runs across the long dimension. Soft/hard indicates the degree of transition.
