Reducing light to control exposure is the job of a neutral density (ND) filter. A variable neutral density filter (VND) replaces numerous ND filters by allowing you to change the amount of light it holds back with a simple twist of its ring. A ProMaster Basis VND filter can reduce light by as little as 2 f-stops or as much as 8. And it can be adjusted to any amount in between these values. There are good reasons to hold back light in still photography as well as videography. Some examples include: In still photography, a VND filter can allow your camera to use a slower shutter speed. The slower shutter speed creates blur with moving objects as a creative effect. One example is blurring water to give the impression of movement. In videography the camera\u0026amp;rsquo;s shutter speed (frame rate) is often fixed, leaving the lens aperture to control exposure. But what if a large aperture is desired to achieve a shallow depth-of-field in bright conditions? A VND is used to reduce the light and thereby achieve proper exposure even with a large aperture setting. All ProMaster Basis filters have the same size filter thread on the front and back. So, they are compatible with your lens cap, and they can be stacked with other, same-size filters. Basis filters represent a terrific value. They are optically excellent and affordable and deliver great results!
