This 4 x 5.65", 4-stop Formatt Hitech Hard-Edge Vertical Graduated ND Filter enables you to enhance 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 where 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.

Formatt Grads are Available in Four Types
Soft Edge - Half clear, half colored with a smooth transition to full density. Generally used with medium to wide angle lenses
Hard Edge - Half clear, half colored with a definite less subtle transition. For use with long focal length lenses
Razor Edge - As hard edge but with a solid transition line for shooting corners of buildings, knife-edge horizons or when a very bold transition is required
Blender - The grad line is right at one edge of the filter so the color change runs from top to bottom. Perfect for irregular objects and skylines
