Innovation and experience
“Made in Germany“
For more than 65 years, B+W filters have been synonymous
with quality and innovation. Following the merger with Jos.
Schneider Optische Werke GmbH in 1985, the company moved
into its current premises in Bad Kreuz­nach. Under the umbrella
of Schneider-Kreuznach a lively technology transfer developed.
B+W has succeeded in establishing itself as one of the world‘s
leading filter manufacturers. It has, for exam­ple, made decisive
progress in surface coating. B+W is the first filter manufacturer
in the world to offer MRC (Multi Resistant Coating). MRC nanocoating is the most innovative development in thin-layer technology. The world-famous Käsemann-type polarizing filter with
its outstanding quality has been produced by B+W since 1989.
Today, state-of-the-art production equipment, precise CNC
machines and highly advanced reflection-reducing technology
guarantee top quality which is amongst the very best to be
found on the world market.
When it comes to technology products, a 65-year company history is corroboration of recognized top quality. Comprehensive
know-how and state-of-the-art production technology have made
a name for the proverbial B+W filter quality of SchneiderKreuznach throughout the world. B+W filters also perform
creative tasks in digital photography. Improving photographic
results without touching the data record can only be done with
first-class filters. The name B+W guarantees perfect image quality.

B+W filters for better quality in digital photos
Top performance thanks to Multi Resistant Coating
(MRC)
Particularly in digital photography, B+W filters are important tools
for improving image quality. A B+W polarizing filter, for example,
provides more saturated colors and higher color contrasts
because the bluish-gray haze typical of sunny days is filtered
before the image sensor generates the data record. If UV or IR
radiation causes haze or blur a UV/IR blocking filter in front of the
lens can ensure more brilliance and detail sharpness without the
necessity for coarsening resharpening in the image program.
Filters solve problems before they occur in the image sensor.
Image-processing programs, on the other hand, cannot conjure
up information which is not contained in the data record. Many
of the most commonly used color and contrast corrections work
by removing image information (destructive image correction).
Such, in some cases coarse repairs leave considerable gaps in
the data record which are not yet recognizable on the PC monitor,
but can become visible on the higher-resolution print.
Safety through high-tech production
B+W is the first filter manufacturer in the world to offer MRC (Multi
Resistant Coating). This multi-layer coating is vapor-deposited
in highly advanced vacuum coating plants. It is extremely lowreflective and highly resistant to scratching. But above all its
unique dirt and water-repellent surface makes cleaning the filters
easier. In this way, filters can also perform a protective function
for the front lens.
A key criterion for an outstanding filter is the coating. Quality
begins in front of the lens, and that is, of course, where the filter
is placed. A filter must not impair the performance of the optics.
MRC (Multi Resistant Coating) have a multicoating layer on both
sides (7 + 1 on each) which ensures maximum reflection reduction
and thereby eliminates disruptive stray light. In this way, more
brilliant colors and higher contrasts can be attained. Due to the
low residual reflection (0.5 %) MRC reliably prevents ghost or
multiple images which can be caused by back reflection from the
image sensor.
Furthermore, MRC protects the filter from scratching with
increased layer hardness, thereby preserving the high optical
quality. In addition, MRC is dirt and water repellent, which makes
cleaning easier.
The MRC nano coating – all XS-Pro Digital filters have it. The outer
layer of MRC nano has been strengthened in its effectiveness.
The nanotechnology-based characteristic (lotus effect) produces
a better beading effect in water. This makes cleaning the filter
surface even simpler and faster. The hydrophobic surface reduces
fogging. During the transition from a cold to a warm environment,
the fogging on the filter glass surface dissipates within a very
short time.

B+W quality: A brand that keeps its promise
The quality of high-grade filters is determined by various criteria.
Many photographers are aware that the plane parallelism and
transmission properties of glass and the coating are key factors
for image quality. What fewer of them know is that the filter mount
must also meet high requirements as a link in the high-tech chain.
The main purpose of the mount is to hold the fragile filter glass in
place, firmly yet without play, for a long time. However, the glass
must not be subjected to mechanical tension because even the
tiniest deformations can result in visible unsharpness. Nevertheless, the filter must also be able to withstand a strong grip. And
even after frequent use it must ensure easy and precise attachment and removal. A non-slip surface quality makes handling
easier. The mount thickness should be kept to a minimum in order
to prevent vignetting at short focal lengths.
In Bad Kreuznach, computer-controlled grinding and polishing machines produce the highest filter quality from this raw
material in an impressive range of designs and diameters. Special production processes remain the domain of the optimizing
handcraft of experienced specialists. Strict quality checks in all
key production steps ensure seamless production standards.
B+W quality does not come about by coincidence, but is clearly
defined: to manufacture exactly plane-parallel filter discs without
arching or wedge errors (deviating thickness) which could lead to
partial image blurring. The filter glass must be completely flat and
smooth. It is highly polished as roughness would result in scattered light, leading to reduced contrast. B+W filter glass meets
the highest requirements of camera and lens manufacturers and
guarantees optimum imaging quality.
B+W filter mounts meet these requirements to perfection. As a
rule, they are made of brass on highly accurate CNC machines.
The filter glass is kept in place securely but without tension by a
threaded retaining ring that is manufactured with equal accuracy.
Fine grooving (knurling) on the front makes attachment easier.
Black (or silver) hard-chrome plating, clearly legible labeling (and
usually matte black inside surface) ensure lastingly stable image
quality and functionality.
The continuous new development and further evolution of the
B+W filter models and the final inspection of each individual
filter mean that users can always achieve the best possible
photographic results. It is therefore important to give the same
consideration to quality when buying a filter as when selecting
your lenses. 65 years of know-how guarantee top filter quality
to meet global market standards.
To avoid vignetting in the image corners at extreme wide angles
despite the slim design, B+W provides various mount types that
cater for the different angles of view.
Precision-engineered mounts
The stable brass mounts are made on high-precision CNC
machines. Knurling on the front edge ensures non-slip handling
when attaching and removing. Strict quality controls guarantee
exact adherence to the target values.
Close-up and macro lenses provide a simple way of exploring
new motif worlds. With infrared filters you make the invisible
visible and create artistic, fabulous images. For high color
contrasts that still look authentic a polarizing filter is still the
best option, despite the possibilities offered by photo-editing
programs. Furthermore, polarizing filters can eliminate many
reflections. The B+W Soft Pro filters produce a professional
soft focus effect. And for action photography – whether it is
sailing or mountain biking – B+W protection filters shield the
front elements of expensive lenses from scratches and moisture.
Experience the fascination of precise creativity with your digital
camera thanks to high-quality B+W filters.

Behind the globally recognized B+W filter quality is a continuous
process of optimization and quality control which already begins
with the raw glass. Only the finest glass plates are used to manufacture high-precision B+W filter glass, guaranteeing maximum optical
filter quality.

Filter mounts – the mechanical specialists
The important role played by the filter mount and its mechanically
complex task are often underestimated. Although mounts are
supposed to fix the high-quality filter glass in position “for life”,
they must not cause any sharpness-reducing tension in the glass.
B+W manufactures various mount types, mainly out of stable
brass, on CNC machines. The filter glass is screwed into a highprecision retaining ring, applying a pre-specified torque. Besides
the excellent F-Pro standard mount which is suitable for telephoto
lenses up to the most common wide-angle focal lengths, B+W
offers the very flat XS-Pro mount for super-wide-angle lenses.
This eliminates vignetting. For even more extreme focal lengths
there is the oversized mount on which the filter glass protrudes
far beyond the thread of the retaining ring (more under “Filter
mounts”). It is the high-grade mounts that finally make a B+W
filter a true piece of high-tech that you can rely on for many years
to come.
Premium Line
The increasingly short focal lengths of zoom lenses for digital
system cameras increase their proneness to vignetting when
attachments such as filters are used. For this reason, B+W has
developed the new Premium Line series with an extremely narrow filter mount: XS-Pro Digital. It is ideal for demanding DSLR
photography with short wide-angle zooms, beginning at 12 mm
(APS format). Despite its small construction depth, this mount is
fully equipped with a front thread for further accessories such as
lens hoods or snap-in lens caps. This filter series is also made of
brass and comes in matte black to prevent reflections.

B+W Filter Mount F-Pro
The standard Filter Mount F-Pro has high mechanical stability
despite its shallow design. It can be used on most wide-angle
lenses without the danger of vignetting. However, exact data
regarding focal length and angle of view limitations are not
possible because vignetting depends not only on the height
of the filter mount and the angle of view, but also on the tube
design of the front of the lens. As a guide, this filter mount can
be used without vignetting on 35 mm camera lenses (approx.
63° diagonal angle of view). In addition, most wide-angle lenses
with 28 mm (approx. 75° angle of view) and in many cases even
with 24 mm (approx. 84° angle of view) can be combined with
the F-Pro mount without the risk of vignetting. The same angles
of view apply to lenses in digital cameras. Despite the thinner
design, others filters, snap caps or lens hoods can be attached
easily and safely to the front thread.
Another advantage of the new F-Pro filter mount: the filter glass
is no longer held in place from the front, but from the back by
the retaining ring. This prevents the retaining ring from being
accidentally loosened during the removal of an additional filter
or a lens hood that has been screwed in too tightly.

Active photography demands a great deal of cameras and
lenses. It therefore makes sense to protect the sensitive front
element of the lens against flying sand, dust, fingerprints and
water with a filter. Filters not only cost a fraction of the price of
a lens, but are also easier to clean. B+W protection filters can
remain permanently in front of the lens as they are absolutely
colorless, highly transparent and extremely low-reflective due
to their hard MRC finish. The optical information reaches the
image sensor uninfluenced. The filters have no exposure factor.
Protection factors play a particularly important role in digital
photography. Larger depth of field due to small sensors increases
the influence of front lens soiling on image quality. Particularly
in zoom lenses with low light intensity, fingerprints have the
effect of reducing sharpness considerably. Frequent cleaning of
the front lens, however, can not only cause scratching, but also
transport dirt particles or moisture on the edge of the mount into
the inside of the lens system.

B+W Protection Filter Clear
Tip for filter cleaning :
Multi Resistant Coating with pearl effect
This filter fulfills the desire of many photo­graphers for pure lens
protection without a filter effect. Its only function is to keep
dirt, sand or splashes away from the front lens. The extremely
clear special glass with high transmission is MRC or MRC nanofinished. The hydrophobic coating reduces the adhesion of particles and water drops. The advantages are easy cleaning and
maximum reflection reduction. Also available for super-wideangle lenses.
To guarantee perfect image quality, filters must be kept clean.
This is supported by the hard MRC finish with its dirt and waterrepellent coatings.
This is the best way to clean filters: Never rub off dry, loose dirt
particles, but remove them first with compressed air (if possible
without touching) or a soft lens brush. Breath on the particlefree filter surface and clean it gently with a soft B+W Photo Clear
microfiber cleaning cloth. For difficult stains, B+W Lens Cleaner II
spray is helpful. Little effort for constantly perfect image quality.
Do not use paper tissues for cleaning as their fibers cling to the
filter due to being electrostatically charged.
B+W Protection Filter UV
The classic among the protection filters blocks the unwanted UV
component contained in daylight. The invisible UV light occurs
more in pure sea air and in the mountains, and can lead to blur and
blue cast. The colorless UV filters are suitable for both analog and
digital cameras and ensure more brilliant pictures. They can remain
permanently on the lens to protect it from dirt and damage. A highgrade MRC or MRC nano finish provides optimum reflection
reduction.
B+W Lens Cleaner II Cleansing Spray
Persistent marks on highly sensitive optical surfaces cannot be
removed with a cloth alone. The B+W Lens Cleaner II has been
developed for this purpose. It is a cleansing solution with highly
effective cleansing agents which leave no unwanted residue on
the glass. The propellant-free pump spray is simple to use, nonflammable and bio-degradable (without alcohol). Indispensable
for photo trekking or outdoor action photography.
Lens Cleaner II is also suitable for LCD/TFT screens.

Polarizing Filters –
reflection reduction par
––––––––––––– .
Radiant white clouds against a deep blue sky or saturated fall
colors are no coincidence. Polarizing filters (pol filters for short)
block the bluish gray veil from the diffusely polarized light of the
sky. They augment the purity of true colors and increase color
saturation. Polarizing filters are amongst the most important
filters in (digital) photography. They can be rotated in the mount,
allowing the visible regulation of the elimination effect in the
viewfinder or on the display. The filter factor of a polarizing
filter is approx. between 4 and 8, equivalent to nearly three
f-stops. With the High Transmission Käsemann HTC polarizing
filter the filter factor is approx. 2 to 3, which is equivalent to
approx. 1 to 1.5 f-stops. The maximum effect is achieved at
a shooting angle of 90° to the sun. For an even effect in the
picture, 35 mm (or 28 mm in 35 mm film format) should be
the minimum. The second beneficial effect of pol filters is the
reduction of reflections on non-metallic surfaces (water, shop
windows, lacquer). Objects behind these surfaces, including
writing behind reflecting lacquer, are made visible – a fascinating
way to enhance images without using photo editing.

B+W Circular Polarizing Filter
B+W Käsemann High Transmission Polarizing Filter
B+W S03 circular polarizing filters are equally suitable for both
analog and digital cameras. The filter is of high optical quality and
designed for all cameras with and without interior measuring devices (autofocus, exposure meter). This filter reduces reflections of
non-metallic surfaces and increases color saturation and contrasts.
For this high-end polarizing filter the foil pieces are selected
individually for maximum color neutrality. Following cementing between high-grade optical glass, additional grinding and
polishing takes place. This guarantees outstanding sharpness
even with very bright, apochromatic lenses. The latest cementing technique ensures lasting stability even in damp climates.
The new generation of Käsemann High Transmission (HTC)
polarizing filters is fitted with a new polarizing foil which has
higher translucency (transmission), yet still provides outstanding effectiveness. The filter extension factor is only 2 to 3,
equivalent to approx. 1 to 1.5 f-stops.
Available in the F-Pro filter mount exclusively with MRC; in the
XS-Pro mount exclusively with MRC nano.

Transmission τ (%)
ND filters or neutral density (ND) filters are used if too much
light restricts creative possibilities. They reduce the light in
accordance with their density. They therefore allow longer
exposure times or more widely opened apertures. Applications are highly varied and in some cases experimental. For very
bright motifs in the snow or on the beach the aperture would
also have to be closed, despite minimum exposure time. This
would mean losing the option of short depth of field, e. g. for
portraits. ND filters can produce wipe effects in movements if
the exposure time can be extended with the required aperture.
A waterfall then no longer appears to be frozen, but as a flowing
motion. ND filters create ingenious effects in architecture or
urban photography. With long exposure times of several hours,
people walking through the shot are blurred or not reproduced
at all. For physical reasons, very dense filters possess a warm
tone which can be compensated in image processing.

B+W ND Filters 101 and 102
B+W ND Filter 106
The ND filter series begins with low light attenuation. Type 101
reduces the light by exactly one f-stop (filter factor 2x), type 102
by two f-stops (filter factor 4x).
With its light reduction by six f-stops (filter factor 64x) this filter
allows even more extreme experiments. This includes timeexposure effects such as light trails, flowing effects for moving
water or walking people who become indistinct in soft focus.
A physically induced higher red transmission produces a slightly
warm tone. If necessary, this can be eliminated by white balance
or an image processing program.
The moderate extension of the exposure values is recommended
for indoors or outdoor shots with little light. At lower shutter
speeds, creative soft focus effects, wipe effects and flowing
effects for waterfalls can be achieved. Opening the aperture
allows selective focus instead of deep focus – a desired effect
when filming videos with DSLRs.
B+W ND Filter 103
B+W ND Filter 110
This already quite strong ND filter reduces the light by up to three
f-stops, equivalent to a filter factor of 8x. It offers more options
than weaker ND filters. This is already sufficient for successful
time-exposure effects, and it can also be regarded as a universal
ND filter in digital photography. White balance with the filter
ensures optimum color neutrality. Tip: Remember to use a tripod
for longer exposure times!
With exceptional light reduction by a full ten f-stops (filter factor
1000x) the 110 continues what begins with the 106: experimental
photography with very slow shutter speeds. Continuous light
trails, walking people on roads and squares become indistinct
or even “invisible.“ The flowing effect for moving water becomes
even more extreme.
For physical reasons, the filter produces a slightly warm tone
which can be eliminated by white balance or an image processing
program.
PLEASE NOTE: ND filters must not be used for direct visual solar
observation (risk of blinding). They let through UV and IR rays
which harm the eyes.

B+W XS-Pro Digital ND Vario MRC nano
Flexible light control without changing filters: The newly developed Vario ND filter can be adapted in its effect to a wide range
of subject situations and photographic requirements. Portrait
photographers, for example, usually also need large apertures
in bright ambient light in order to separate their model optically
from the background. Using several minutes of exposure time,
architectural photographers can make people passing through
the motif “invisible”. In landscape photography, flowing water or
the surface of the sea can be made to appear fluffy and soft with
long exposure times: classic situations which make the use of an
ND filter indispensable.
Thanks to its infinitely variable density, the first B+W Vario ND
filter can be adjusted exactly to individual requirements. To this
end, it comes with a continuous setting function with which the
photographer can determine the required density between +1
and +5 f-stops. To prevent aberrations, the light reduction cannot
be set beyond a critical level. The XS-Pro Digital ND Vario MRC
nano thus guarantees professional image results, even with high
filter factors.
ND Vario values
Thanks to the double-sided multicoating layer, the proven B+W
MRC (Multi Resistant Coating) nano coating eliminates unwanted
stray light and delivers visibly more brilliant colors and higher
contrasts. Due to the extremely low residual reflection, ghost
or multiple images which occur due to back reflection from the
image sensor are also avoided. The outer layer treated with nano
technology (lotus effect) allows water to bead off far better and
makes cleaning the filter easier.
Tip: DSLR photographers should cover or close the optical viewfinder during longer exposure times in order to avoid measuring errors. Like all B+W ND filters the XS-Pro Digital ND Vario
MRC nano also works on a color-neutral basis. At high densities,
slight chromatic aberrations in the image may occur for physical
reasons. These can subsequently be eliminated with ease using
white balance or by working in RAW format in the image-editing
program. When using a full-frame camera, the focal length should
be no less than 35 mm to achieve maximum image quality when
selecting higher densities.
The B+W ND Vario filters are oversized and therefore suitable
for wide angles. Hence the difference between the lens connector thread and the front connector of the filter.

Info
Due to different directions of light incidence (light rays scatter
differently in the center of the picture than at the edges), an
aberration may occur when taking the picture. This first becomes
visible in the corners and in extreme cases it can appear in a
cross pattern. This becomes noticeable with wide angle lenses
28 mm (equivalent to 35 mm format) and less. These irregularities also occur with excessive dimming. As the B+W ND Vario
features a stop for the brightest and darkest positioning, this is
avoided.
In order to obtain even image results the focal length should not
be less than f = 28 mm (35 mm).

Close-up lenses reduce the minimum focus, produce clear details
Close-Up Lenses – small world in XXL.
Close-up lenses – reading glasses for your lenses
Would you like to explore fantastic worlds in miniature? Close-up
lenses open up new motifs in an inexpensive way. Like reading
glasses, close-up lenses move the focus range into the close-up
zone. The effect increases with the diopter number and the focal
length of the lens. For shorter focal lengths in digital photography
stronger close-up lenses are therefore recommended. The image
scale describes the effect. A scale of 1 : 3 renders an object at a
third of its original size on the film/sensor. Close-up and macro
lenses are simple aids which are suitable in particular for threedimensional objects (flowers) and pictorial photography, less
for technical reproduction purposes. Sufficient stopping down
increases the sharpness and the depth of field.
Tip: Use a tripod for longer exposure times.
B+W Close-Up Lenses
As clearly illustrated, the stronger the close-up lens, the closer
you can get to the subject with the same distance setting and
the larger the image you can obtain. A longer exposure time
is not necessary. B+W close-up lenses can be combined, but
for quality reasons and to prevent vignetting no more than two
lenses should be mounted over each other. The values are simply
added together.
B+W Macro Lens
With extremely high +10 diopter power this close-up lens goes
beyond the normal scope. Its high refraction is ideal for the
short focal length of digital photography. Even at a focal length
of just 50 mm you enter the macro range, with an image scale
of approx. 1: 2. To increase (depth of) focus, stopping down by
three f-stops is recommended. If graduated sharpness is part of
the image concept, open apertures can also be used.

Soft Focus Attachment
The term “soft focus attachment“ does not do justice to this
soft filter. The filter delivers sharp pictures which are softly overlaid with unsharpness. Details such as eyelashes do not taper
into unsharpness, while skin blemishes are gently covered up.
Small mini-lenses are distributed randomly on a precisely planeparallel glass disc. They scatter the light and overlay the sharp
core image with hazy, diffuse halos. This opens up deep shadows,
while highlights themselves are hardly blurred, but instead form a
shimmering aura in the darker surroundings. Professionals, even
in Hollywood films, use these stable glass filters when aiming
for perfect beauty shots. The effect cannot be achieved with
image-processing software (e.g. Gaussian blur). As well as for
portrait photography, soft focus attachments are frequently used
for great effects in landscape shots. They reduce high contrasts
and the light fringes in the backlight are softened. The photographs take on a gentle, romantic character.
Cross Screen, 4x, 6x and 8x
B+W effect attachments make unusual photos possible. Suitable
motifs become even more attractive. This results in pictures with
a look that stands out positively when it is consciously employed.
Cross screen filters consist of high-quality optical glass into the
surface of which fine grating structures are integrated. Depending on the form of grating, light sources or bright reflections
shine in a multi-star pattern that surrounds them. It is important
that the light sources are bright and dot-shaped. Then the subtly
colored star effect forms in very high definition.
B+W Soft-Pro – precise beauty softener
A special soft focus attachment with irregularly distributed microlenses on precisely plane-parallel clear glass. The sharp core image
is overlaid with a soft unsharpness. Ideal for dreamlike feminine
portraits, softly shimmering, backlit blond hair, soft dream landscapes, and all without much loss of sharpness. The B+W Soft Pro
largely retains the overall contrast, working almost independently
of focal length and aperture, thereby allowing control of the depth
of field. It poses no difficulties for autofocus systems.

Graduated ND filters – balance between heaven and earth
Graduated filters 701 and 702 as sheet filter 100 x 150 mm
Graduated filters are colorless and compensate excessive
contrasts between the sky and the landscape. Clouds gain
definition, sky blue acquires depth. The filters can be rotated
in the mount in order to adapt the graduation to the horizon.
Alignment is performed in the viewfinder or on the camera’s
display. If exposure metering is done through the filter, a minus
correction of approx. 0.5 is advisable. The graduation is applied
by means of thin layer technology.
B+W graduated filters 701 and 702 are also supplied as
100x150x2 mm sheet filters. The rectangular sheet filters can be
moved and rotated in the compendium for exact alignment to
the horizon. They are suitable for compendia with filter channels
designed with 100 mm width and 2 mm thickness, e.g. LEE,
Cokin Z and Lensinghouse Gron compendia.
B+W Graduated ND Filter 701 – 50 %
The neutral-gray half of this graduated filter with transparency
of 50 % (1 f-stop) darkens the motif area by one f-stop without
changing the colors. If, for example, the sky is too light in relation
to the landscape, this is the ideal value for good cloud rendition and to prevent the blue sky from becoming too pale due to
overexposure.
The glass substrate of the B+W graduated filters 701 and 702 is
a ground and finely polished filter sheet. This guarantees high
optical quality which is also very long-lasting.
The filter sheets are dimensionally stable thanks to the glass
substrate and cannot warp or distort. They are more resistant
to scratching. The sheets are supplied in shatterproof tin plate
cans.
B+W Graduated ND Filter 702 – 25 %
Extremely well defined clouds and a full-bodied instead of milky
tone in the sky – these are the effects produced by this already
stronger graduated filter. It attenuates the light in the darkest
zone by two f-stops (transparency 25 %). Very high-contrast
landscape motifs without loss of definition become possible.
The graduation zone allows some degree of tolerance, but for a
natural transition the horizon line should not be positioned too
far from the center of the image.
B+W 701 MRC, 50%
B+W 702 MRC, 25%
Graduated MRC filter as 100 x 150 x 2 mm sheet filter.
Additional information:
The gray gradient is applied by means of thin-layer technology.
The special coating process requires a special masking. This is
associated with certain manufacturing tolerances, with the result
that the graduation boundary is not exactly parallel. Because this
transition is outside the focus range, the effect is not visible and
there is no static transition.

Infrared digital – special filters for extreme contrasts
B+W Digital UV/IR Blocking Filter 486
The two special filters Infrared Filter 093 and UV/IR Blocking
Filter perform opposing tasks. The UV/IR Blocking Filter 486
blocks unwanted ultraviolet and infrared light components that
can produce ghost images and sharpness-reducing interference.
The images gain sharpness, detail and fine color gradations.
Digital cameras have similar filters in front of the image sensors;
nevertheless, considerable residual transmission is detectable
in the infrared range. A gap that is closed by the UV/IR Blocking
Filter 486.
This filter has a steep cut-off effect for unwanted ultraviolet
and infrared light. In digital cameras and camcorders without
full filtering in front of the image sensor it prevents color casts
and unsharpness. The brilliance and sharpness of the images are
increased. This takes place by interference between vacuumdeposited layers and not by absorption via colored glass. This
principle is ideal for angles of view up to 60° or smaller. The filter
has no exposure factor.
It is precisely this gap that the Infrared Filters 092 and 093 make
use of. Digital cameras with sufficient IR residual sensitivity take
highly typical infrared pictures when the visible light is blocked.
The black-red Infrared Filter 093 is ideal for this task. The image
section is selected and infrared focusing performed before
attaching the filter.
B+W Infrared Filters 092 and 093
The B+W Infrared Filter 092, which is almost black but when
placed in front of a light source is in fact dark purple. It blocks
visible light up to 650 nm, and only at just under 700 nm it transmits 50 % (hence the dark-red color). For 730 nm to 2000 nm the
transmission is very high with over 90 %. This allows shots of the
pure red and infrared image. This IR filter is suitable for most
digital cameras.
Tip: Digital infrared photography
Whether or not a digital camera is IR-sensitive can be determined
with an IR remote control. Instructions can be found on the Internet. The IR focus point is somewhat further away than that for
visible light. With the filter attached, white balance is performed
automatically or (preferably) manually. The IR photos are optimized in the image-processing program: Increase contrast automatically or in the histogram, convert color images to black and
white or experiment with individual color channels, leaving the
red channel on maximum. No matter whether digital or analog,
infrared photography is experimental by nature.
The IR filter 093 blocks visible light (up to 800 mm) almost
completely. It is dark red, almost black. With analog IR film or
IR-sensitive digital cameras it delivers a fantastic wood effect
(white leaves) and a typically dark sky. The exposure values vary
according to the digital camera model being used and are best
determined by experimenting. They are usually in the range of
a few seconds. Focusing is performed first without a filter using
IR focus correction.

Black and White Filters 022, 040, 090, 091
Consciously composed black and white photography enjoys
undiminished popularity. However, the conversion of the colors
into gray-scale values does not correspond to the brightness
perception of the human eye, in neither film nor digital photographs. Filters are therefore indispensable for black and white
photography.
A simple rule explains the mode of action: The filter’s color
is made lighter, the complementary color is made darker. An
apple tree serves as a good example: When using a red filter, a
red apple appears lighter and the green leaves are reproduced
darker. In contrast, a green filter lightens the leaf green and darkens the red of the apple.

Yellow filters very visibly increase the contrasts (by darkening
the sky) in landscape photos. The pictures gain more brilliance,
with plant green receiving more differentiated reproduction. A
medium yellow filter is regarded as the standard filter in black
and white photography. An orange filter increases this effect,
making a diffuse sky of clouds appear much more dramatic. The
skin blemishes of a model (red patches) are also concealed.
The group of the red filters increases this effect to the point of
estrangement. A summer landscape photo with a cloudy sky is
transformed into a dramatic storm mood (wood effect), and a
dune landscape becomes a moonscape with an almost black sky.
Black and white filters also improve the resolution and sharpness
of the image. With these filters the lens is used only in a narrowband or even monochromatic color spectrum. All the chromatic
aberrations of a lens, such as longitudinal and lateral chromatic
aberrations, are significantly reduced or almost completely eliminated, depending on the filter. Light that was previously filtered
is no longer “available” for aberrations.

Accessories
B+W Adapter Rings
B+W Collapsible Lens Hoods1
If photo equipment is to include lenses with different filter thread diameters, the B+W adapter
rings can adapt filters and supplementary lenses
to different lens diameters. This is less expensive
than buying several lenses with the same filter
type – money that would be better invested in a
larger selection of filters. When buying filters, first
check the largest diameter required. When there
are three different diameters to cater for at the
same time, adapter rings can also be combined if
necessary. Increased thickness due to using several
mounts can result in vignetting. B+W offers a wide
range of adapter rings.
Collapsible lens hoods are made of high-grade
rubber. Their advantage compared to fixed lens
hoods made of plastic or metal is that, in their collapsed state, they protrude only a short distance.
This means that the lens hood can remain attached
to the lens and, together with the camera, will also
fit into a tight photo bag.
B+W Snap Cap Pro 3112
Hard plastic cap with two spring-loaded plastic
claws opposite each other that engage the front
thread of the lens (or filter). Simple removal by
pressing the two buttons together means fast and
uncomplicated one-hand operation. Available for
thread sizes 52, 55, 58, 62, 72 and 77.
Lens hoods are usually regarded simply as a kind
of sun visor. In fact, stray light occurs not only by
sunlight obliquely striking the lens, but also due
to bright ground surfaces (snow, beach), diffuse
light or (in object photography) bright surroundings such as a light table. Blocking stray light can
considerably improve the image quality of even the
most expensively coated lenses.
• The B+W Lens Hood 900 is tailored to standard
lenses and short telephoto focal lengths. Its inner
ribbing enhances the light-absorbing effect of
the matte black surface. In its collapsed state,
the rubber hood increases the length of a lens by
only one centimeter (up to 77 mm filter thread).
B+W Slip-on Front Lens Cap 300
Protective cap made of flexible plastic material that
slips over the outer front rim of the lens or filter. It
remains in place by means of friction of the slightly
elastic, slip-proof plastic material. Also very simple
to handle. Available for lens or filter front rim diameters of 27, 30, 32, 37, 42, 51, 54, 57, 60 and 70.
B+W Metal Lens Hoods
B+W metal lens hoods convey a reassuring, stable
impression by their very appearance. The black
anodized aluminum reliably blocks stray light, and
the precision-engineered tubes have black inner
ribs for even greater absorption of unwanted light.
Three types are available for numerous filter sizes:
