82mm Neutral Density 2 Stop (102) SC F-Pro

B+W ND (neutral density) filters, reduce the whole visible light spectrum in a uniform manner and thus lead to a reduction in light intensity without affecting colour and contrast. Uses for ND filters - Sometimes large apertures are needed in bright ambient light in order to separate a model optically from the background. Using several minutes of exposure time, architectural photographers can make people passing through the work space “invisible”. In landscape photography, flowing water or the surface of the sea can be made to appear fluffy and soft like cotton candy. 
This B+W ND filter, which reduces the light by two f-stops, already shows a clear effect on your photographs such as requiring f/4 instead of f/8 for selective focus or 1/15 sec instead of 1/60 sec for a long exposure effect. The filter is color-neutral, and it should be part of any basic DSLR photography equipment kit.
