black white filters also for digital black and white filters are color filters for photos on black and white film but also for digital shots which should be output in black and white via a camera function or subsequently using a photo-processing program they are designed to modify the conversion of the colors into gray values such that the actual color and its related colors are brightened while the complementary colors and their related colors are darkened b+w black and white filters are available in a number of stages from bright yellow to red and in yellow-green and in green the bright yellow filter 02¡ suppresses violet and attenuates blue thus the blue sky appears a little darker in the photo white clouds are emphasized the medium yellow filter 022 and the dark 023 attenuate blue a little more in each case the blue sky is made correspondingly darker yellow orange and red appear brighter in contrast all three are ideal for landscape photos since white clouds are reproduced

clo se -up lense s /macro lens close-up lenses expand the close-up adjustment range of analog or digital cameras for much larger imaging scales in a simple manner the b+w close-up lenses nl ¡ to nl 5 with +¡ to +5 diopters allow a matching to the focal length of the lens close-up lens nl ¡ is ideal for zoom lenses up to around 200 mm with a near focus limit of around ¡ m nl 2 is recommended for standard lenses with a near focus range of up to around 50 cm or for zoom lenses where nl ¡ is no longer sufficient nl 3 permits an even greater near focus when nl 2 also does not do enough for zoom lenses and for wide-angle lenses which can be focused to around 35 cm nl 4 continues the range of nl 2 for standard lenses and is the maximum for portrait zoom lenses nl 5 continues the focusing range of the wide-angle lenses beyond that possible with the nl 3 the b+w macro lens ¡0 diopters has been specifically designed for digital compact cameras also for digital closest focusing distance

cro s s s cre en att achment s the b+w cross-screen effect attachments have a linear grid pattern at which stars are created at light spots which produce attractive effects on a dark surrounding field of the light spots the stars largely have the same color as the light source but can also have weak spectral colors the ray direction is always at right angles to the extent of the lines rotary mounts permit optimum alignment in the viewfinder of a reflex camera or on the monitor of a digital camera all three b+w cross-screen attachments may also be used with video cameras the b+w 4x cross-screen attachment has a rectangular line grid with a square grid pattern the b+w 6x cross-screen has a grid of lines in the directions of the sides of an equilateral triangle the rays therefore form angles of 60° in each case the b+w 8x cross-screen has the appearance of two right-angled line grids placed over one another offset by 45° with respect to one another the rays it forms create pairs of

filter mount s and adapters b+w standard filter mount f-pro the b+w standard filter mount f-pro provides some substantial enhancements over the previous b+w standard mount it has been given a shallower design while maintaining the excellent material and production quality and its unchanged high mechanical stability and can therefore now also be used without any risk of vignetting for many wide-angle lenses while no exact focal length limit can be given since the vignetting depends not only on the height of the filter mount but also on the tube design of the lens it can generally be considered that the b+w standard filter mount f-pro can be used without any vignetting with 35 mm film and indeed always up to 35 mm almost always at 28 mm and frequently even at 24 mm focal length another advantage of the new f-pro mount is that the screw ring which holds the filter glass in the mount is no longer inserted from the front but from the rear this means that the screw ring can no longer be
