The B+W 77mm MRC 0.6/4x (102) Neutral Density Filter reduces the light by two f-stops (log density 0.6) & 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 & blurred water instead of a “frozen” waterfall. It has excellent colour neutrality & is recommended as part of a basic outfit. ...

The B+W Neutral Density+3 F-PRO Digital Filter reduces the light intensity by three f-stops (log density 0.9). It still features very good color neutrality. This ND filter is especially appropriate for use on video cameras when the lens cannot be stopped down sufficiently in great brightness or when a deliberately low depth of field is desired. The filter factor is 8x. ...

The B+W Neutral Density+6 F-PRO Digital Filter reduces the light by six f-stops. With this filter & without changing the f-stop, a shutter speed of 1/60 s is changed to a full second, thus requiring the use of a tripod. Moving water is rendered as blurred & flowing in the photo, & people moving in streets are dissolved in unsharpness or become invisible. Because of its higher transmission in the red beyond 660 nm, this filter brings a slightly warm tone to colour photographs. If this effect is undesirable, a B+W UV-/IR-Blocking Filter 486 in front of the neutral density filter (not behind it) remedies that situation. The filter factor is 64x. ...

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 & documentation of industrial processes with extreme brightness, such as steel furnaces, incinerators, glowing filaments in halogen- & other bulbs. However, it is being increasingly used in artistic photography to blur motion or render moving elements invisible. The filter factor is 1000x. ...

The B+W 77mm MRC Basic Circular Polariser Filter is a versatile accessory for any photographer, perfect for landscape shots & holiday snaps. With its Multi Resistant Coating, it repels water, dust, & oils, & is easy to clean. Its precision filter mounts made from brass make it durable, robust & easy to mount & dismount. ...

This 77mm protection filter with MRC (Multi-Resistant Coating) by B+W can be used to protect the front element of your lens from dirt & scratches. The MRC is not only an extraordinarily effective multiple layer anti-reflection coating, it is also harder than glass, so that it protects filters from scratches (for instance when cleaning the filters), & it is also water & dirt repellent. ...

The B+W 77mm MRC Clear UV Haze (010) Filter blocks the invisible UV component of light from the sky, which can cause blur & a blue cast. UV Filters are ideal for photography in high altitudes (in the mountains), by the sea & in regions with very clean air. Because the glass is colourless, colour rendition is not altered, aside from the elimination of the unwanted blue cast, & no increase in exposure is required. That makes a UV Filter very suitable as protection of the front element of the taking lens against dust, s&, sea water spray & the like, & it can be kept on the lens at all times. ...

This B+W 77mm MRC UV/IR (486M) Interference Filter has a completely colourless glass carrier coated with a number of extremely thin, partially reflecting layers with precisely computed thicknesses, similar to MC coating. The B+W Filter 486 does not block by means of absorption, but by interference of the unwanted UV & IR radiation that is repeatedly reflected between these layers, affecting the wavelengths on both sides of the visible spectrum with a steep cut-off. It is used mainly on digital & video cameras with CCD sensors without an integrated IR protection filter, because the IR sensitivity of the CCD sensor would otherwise cause colour changes & unsharpness. That unsharpness results from the chromatic aberration of the lenses that are only corrected for visible light. In the visible range, the transmission curve is very high & straight. This filter is completely clear & it requires no increase in exposure. Its filter factor is 1. ...

This 77mm UV Filter blocks the invisible UV component of light from the sky, which can cause blur & to which many colour films react with a blue cast. UV Filters are ideal for photography in high altitudes (in the mountains), by the sea & in regions with very clean air. The pictures gain brilliance & disturbing blue casts are avoided. Because the glass is colourless, colour rendition is not altered, aside from the elimination of the unwanted blue cast, & no increase in exposure is required. That makes a UV Filter very suitable as protection of the front element of the taking lens against dust, flying s&, sea water spray & the like, & it can be kept on the lens at all times. Please note that due to the low-profile slim construction of this filter it is not possible to fit a clip-in lens cap to the front. ...

The B+W 77mm Slim KR-1.5 MRC Skylight Filter is a delicate reddish-yellow conversion filter that absorbs violet & some blue plus a minimal amount of green, but it passes yellow & red undiminished; the colour of the light becomes &8220;warmer” by 15 Mired. That is mostly the optimal amount for correcting the light blue cast in the shadows under a blue sky. It also absorbs UV radiation & hence it provides better sharpness. With colour films and/or developing processes that generally yield results that are too &8220;cool, " this filter can be kept on the lens at all times. With this filter, skin tones in particular will be rendered more naturally. ...
