The B+W 77mm 0.6/4x (102) Neutral Density Filter reduces the light by two f-stops (log density 0.6) and is the most popular ND filter in photographic work. It offers many benefits, for instance f/4 instead of f/8 for selective sharpness instead of a great depth of field, or 1/15 s instead of 1/60 s for a flowing and blurred water instead of a frozen waterfall. It has excellent colour neutrality and is recommended as part of a basic outfit.

The Tiffen Variable Neutral Density filter is a versatile and flexible tool providing 2 to 8 stops of light control, affording you the convenience of using several Neutral Density filters all in one. Primarily used as a photographic tool for controlling depth of field and exposure, the Variable ND is being sought in the video market as well because it is fast, easy to use, small, lightweight, and does not require additional accessories such as a matte box.
With a light intensity reduction of ten f-stops, this B+W Neutral Density Filter has a slightly stronger warm tone than the ND 6 stop filter. Its principal field of application is the observation and documentation of industrial processes with extreme brightness, such as steel furnaces, incinerators, glowing filaments in halogen- and other bulbs. However, it is being increasingly used in artistic photography to blur motion or render moving elements invisible. The filter factor is 1000x.
