The Cavision 5.65 x 5.65" Graduated Green 1 Glass Filter can make a run-of-the-mill sunrise or sunset into a memorable image. This unique filter adds spectacular color to one half the photo while leaving the other half untouched.
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. Sometimes it is also desirable to add color to part of the photograph. For example, to add green to only the foreground.
If you like shooting landscapes and would like to make them into breathtaking studies, this filter can add punch to a flat green foreground. Not only will it add color but it does so with a subtle and extremely gradual transition between the two halves of the filter.
