B+W Filters : Specialist Neutral Density Filters

B+W Specialist Neutral Density Filters

Modern high-speed lenses produce bright viewfinder images in reflex cameras and make fast shutter speeds possible in all types of cameras, even with slow-speed films or under poor light conditions. But their large apertures can also be used as an interesting creative element:

At wide apertures the depth of field is reduced so much that eventually only the main subject will be rendered sharply, whereas the fore- and background will be unsharp. This also focuses the attention on the main subject in a creative sense, it draws the attention of the viewer as if by magic, relegating everything else into the background. In intense brightness, how-ever, with high-speed film or a short focal length (with correspondingly higher depth of field), using a large aperture to achieve the desired selective sharpness effect may not be possible without incurring over-exposure. This is when B+W neutral density filters provide the solution.

B+W's ratings for ND filters are as follows:
0.3=2x
0.6=4x
0.9=8x
1.8=64x
