Cavision 4 x 5.65" Graduated Neutral Density 0.6 Filter
The Cavision 4 x 5.65" Graduated Neutral Density (ND) 0.6 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.
Speaking generally, the 2-stop value (ND 0.6 - the filter's clear portion allows 4x more light to pass vs. darkest portion) effectively compensates average bright sky-to-foreground situations, and the soft transition is applicable more often to a scene than the hard transition.
Neutral Density Filters Have Four Main Uses
- To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
- To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
- To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations
- To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
Neutral Density Factors
- ND.3 (exposure adjustment = 1 stop, reduces ISO to 1/2)
- ND.6 (exposure adjustment = 2 stops, reduces ISO to 1/4)
- ND.9 (exposure adjustment = 3 stops, reduces ISO to 1/8)
- ND1.2 (exposure adjustment = 4 stops, reduces ISO to 1/16)

Comments about Cavision 4 x 5.65" Graduated Neutral Density 0.6 Filter:
Use this with all my Canon L lenses and to be quite honest I don't see that significant of a difference between this and my B+W filters that cost several hundred dollars.
It's versatile and it gets the job done and quite a price drop from anything else you will find like it.
It is very sturdy and has a nice durable frame.

Comments about Cavision 4 x 5.65" Graduated Neutral Density 0.6 Filter:
Being heavy into landscape photography this is a must have. I have another square filter I use, but I was surprised the Cavision filter has a plastic frame around it. Nice touch and it helps prevent smudging.
