The B+W 52mm Light Red (090) Filter is the classic filter for black & white architectural photography & for boosting contrast. White façades glow brightly, the blue sky is darkened dramatically & clouds become more impressive. It is also excellent for spectacular landscape photographs with greatly enhanced distant views. Its filter factor is Approx. 5. ...

The B+W 52mm Medium Yellow (022) Filter provides strong blue suppression extending into the blue-green, meaning that clouds in the sky look very natural, but not yet dramatic, & distant views with light haze become clearer. An ideal filter, especially for landscape & plant photographs, its filter factor is Approx. 2. ...

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 color 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. ...

This 52mm 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 52mm 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. ...

The B+W 52mm Redhancer (491) Filter, made from didymium glass, is a filter with very special transmission characteristics. Designed to strengthen the reddish components of orange, near red or brown subjects, it is very popular for use in nature & landscape photography. It is particularly effective in conjunction with a polarising filter, controlling a potentially bluish-grey veil & for increasing colour saturation, e.g. to capture fabulously vivid scenery during the colourful autumn season. The use of colour reversal film is recommended, because the automatic correction applied by printers to colour negatives can erroneously interpret the desired effect as a colour cast & reduce it by filtering it out. ...

The B+W 52mm Slim MRC Circular Polariser Filter increases colour saturation & reduces reflections. Circular polarizing filters are made for all cameras with beam splitters in the light paths of their TTL exposure meter & with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings. ...
