The Cavision 4 x 5.65" Graduated Neutral Density (ND) 0.9 Filter enables the shooter to adjust exposure without affecting color balance. Neutral density filters are available in 1, 2 or 3 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.
Determining which graduated neutral density filter yields ideal results for any given lighting situation takes knowledge, experience and a collection of such filters. Choose the filter strength which adjusts the lighting to stay within the exposure latitude (greatest difference between bright/dark values) which still shows details in both of the digital or film medium in use.

Comments about Cavision 4 x 5.65" Graduated Neutral Density 0.9 Filter:
This is my second Cavision Graduated ND filter. The other is the 2 stop, so by combining (and I have) I can get up to 5 stops. Easy to use with the plastic frame around them. They also come in a protective nylon sleeve with a very nice clearing cloth.
