Tjis 3 x 4" Glass ND Filter from Cavision reduces the amount of light entering the lens without affecting color. It is used primarily when the light level exceeds that which the film stock or video CCD can handle. This is often the case when shooting on a sunny day in a location featuring an abundance of light reflection such as a desert, ocean, or snowy landscape. If a reduction in depth of field is desired, the neutral density filter can help achieve this because it allows you to open the lens aperture further without overexposing your image.

Cavision Glass ND Filter Reviews
As good as any at a great price.
These are great filters. I shot a test comparing a Cavision ND.9 with Schneider, Tiffen and Smallrig ND.9 filters using a Red Komodo with Nikon Lenses. The Cavision looked just as good as the Schneider and Smallrig filters with no noticeable change in color or contrast. The Tiffen ND.9 was a little more green. Sharpness was identical with all filters. The price of the Cavision is very reasonable and it is great they make a 3x4 size. I just wish they made a bigger variety of filters like 85, 85ND, LLD etc. Highly recommended.
For the price, it's excellent.
I have two Pocket Cameras and a Micro, which means I'm always playing with filters. Given the size of these cameras, and because I handhold most of the time, I prefer a 3x3 matte box - they're much lighter... I'm kind of a snob about what I put in front of a lens though, so I usually go for the high priced spread, but saw this filter for less than half the price of the name brands (most of which don't even offer much in 3x3 size anymore)... If you know about NDs and IR, you know that there can be dramatic color shifts above 0.6 or 0.9. This 1.5 ND is excellent, the footage grades identically to footage shot without an ND using my CC presets in FCPX.
