Formatt Graduated Neutral Density HD Filters enable the shooter to adjust exposure without affecting color balance. Exposure can be increased by 1, 2, 3 or 4 stops to suit individual situations.
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. 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. This filter enables cloud detail to be kept correctly exposed in the picture.
Soft/hard indicates the degree of transition.
