Protection Filters -
Your camera won't allow you to develop clear, crisp photos if your camera lens is damaged or dirty. You can protect your thousand dollar lens with a $20 filter
if you use a UV or haze filter. These thin glass filters are designed to screw onto the end of your camera lens and you can just leave them on to protect your
lens. UV filters can help protect your lenses from dust, moisture and scratches. If your lens is damaged it could cost you quite a bit to repair or replace it.
The filters can also give you added benefits of correction for Ultraviolet light which can show on your film as a bluish cast and can sometimes distort distant
details. UV filters let you correct for the UV effect to varying degrees. They are also useful if you are shooting mountain and marine scenes, as the haze could
affect the color and clarity of the photos. UV filters can be bought for about $20.
Haze Filters Haze. Filters do just what they sound like, they filter out haze which is created by minute particles of vapor and dust. Haze settles in the
atmosphere and can affect distant photographic scenes. Haze forms when sunlight is scattered by minute particles of matter that exist in the air. Atmospheric
conditions have an effect on the amount of haze in the air. Mist, fog, smog, smoke and clouds are all different than haze. Green and red light are scattered by
haze, but not as much as ultraviolet radiation, violet and blue light. If you use filters to absorb scattered sunlight you can penetrate the haze. Any filter that
can absorb scattered sunlight can be considered a haze filter.
B+W Natural Clear 007 Multi-Resistant Coated (MRC) Glass Filter. A B&W 46mm Clear (Colorless) Multi-Resistant Coated (MRC)
Glass Filter is for color as well as black and white films. It also serves as a permanent lens protector. The value of a clear filter covering a lens has been
well-documented over the years. How many stories have we all heard about photographers dropping lenses and smashing front elements? With a front lens protection
filter on, the chances of preserving the valuable glass in your lens increases many fold. Shall we call it a form of inexpensive insurance?
B+W #007 Protection Clear MRC (Multi-Coated) Glass Slim Filter.
B+W Skylight KR-1.5 Filter (1A). This filter also blocks UV radiation, however it also has a delicate reddish-yellow tone
designed to counter-act the high blue cast in the shadow portions of color photographs caused by light coming from a blue sky. It produces a warmer image tone and
reduces the haze in distant scenes. The exposure factor amounts to only ¡.¡, so for practical purposes it can be ignored. Because of its very faint color, a
Skylight Filter can be kept on a lens constantly for protection, as long as a slightly warmer color rendition is desired, as it would be with color reversal films
that tend to produce cooler colors.
B+W Skylight 1A (KR-1.5) Multi-Resistant Coated (MRC) Glass Filter
B+W UV Black (403) Filter. Not to
be confused with UV-blocking filters that photographers
normally refer to as “UV Filters”, this one passes UV A
radiation (320 to 385 nm), but blocks visible light and
looks pitch-black to our eyes. It is used with appropriately
sensitized films in such applications as ultraviolet
reflection photography in forensics or in materials
research, but also as filters on UV-emitters for
fluorescence photography. Depending on the illumination and
on the film’s sensitization, its filter factor is in the
range of 8 to 20.
B+W UV Haze 010 F-Pro Filter This UV Filter blocks the invisible UV component of light from the sky, which can cause blur and to which many color films react with a blue cast. These filters should be called UV-Blocking Filters, because there are filters for technical applications that pass UV radiation and block all the other wavelengths. Nevertheless, the short term “UV Filter” has become established among photographers. UV Filters are ideal for photography in high altitudes (in the mountains), by the sea and in regions with very clean air. The pictures gain brilliance and disturbing blue casts are avoided. Because the glass is colorless, color rendition is not altered, aside from the elimination of the unwanted blue cast, and 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 sand, sea water spray and the like, and it can be kept on the lens at all times. It is recommended for analog color- and black-and-white- as well as digital photography. UV Filters from B+W are also available in SLIM mounts for wide-angle photography without vignetting.

B+W UV-415 (2B) UV-Blocking Filter
- This sharp-cutting, nearly colorless B+W filter blocks UV radiation up to the limit of visible light. It is used in ultraviolet fluorescence photography for the prevention of unsharpness caused by the intense UV illumination (which is due to chromatic aberration in the UV range). It can also prevent the fluorescence that may occur in the cement between lens elements. Because of the usually rather colorful fluo-rescent
subjects, the delicate yellow cast in.
B+W 420 UV-Blocking Glass Filter
- This even more stringent UV-blocking filter behaves like
the filter 4¡5 described above, except that its filtering
slope completely blocks the UV radiation all the way into
the visible violet region. As a result, it has a noticeably
yellow tint. It is used for fluorescence photography on
black-and-white film, where it is even more effective. Its
filter factor is 1.2.
B+W Ultraviolet (UV) FilterA UV filter is the best available protection for the front element of your lens. A lens that accidentally gets dropped on its front element while hiking can potentially be saved by purchasing this item. Some people refer to them as "cheap insurance".
Aside from that more-than-significant benefit, UV filters cut through some of the haze in the atmosphere rendering your photos clearer, sharper and more contrasty.
For those who enjoy outdoor photography, especially distant
vistas, a UV filter can produce a more distinct image by
removing much of the blue tint normally associated with
atmospheric haze. The filter ring is made from brass

B+W 486 Digital UV/IR Blocking Glass Filter.This B+W Interference Filter has a completely colorless 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- and 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- and video cameras with CCD sensors without an integrated IR protection filter, because the IR sensitivity of the CCD sensor would otherwise cause color changes and 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 and straight. This filter is
completely clear and it requires no increase in exposure.
These filters are used to reduce or eliminate reflections. They are ideal for photographing through glass or water as the glare from water tends to be white. Polarizing filters can also reduce the effects of haze and darken the blue sky image in black and white and color photography. There are various polarizing filters available to increase color saturation in a photo without altering the hues of image colors, but there are only two principal styles. One style fits over your camera lens, while the other is made to be used over the source of light. They don't affect color, that's why polarizing filters and screens are used in both black and white and color photography. There are two pieces to a polarizer. The front part rotates so you can change the angle of polarization. If you look at the blue sky through a polarizer and rotate it, the sky appears to get darker and then lighter. These filters range in price from about $15 to $800. They come in various sizes.
B+W Circular Polarizer Filter. The reputation of B+W's Schott glass is world renowned. The high production standards combined with a sturdy brass filter ring make B+W filters hard to beat. These filters have a "heft" to them that is impressive. They may feel heavier but the benefit is in the construction and results. Not only is the glass exceptional but so is the seal between the ring and glass.
Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.

B+W Warm Circular Polarizer 81A Glass Filter. Light rays which are reflected become polarized. Polarizing filters are used to select which light rays
enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast.
The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. Filter factor is between 2.3 and 2.8 (approx. +1.3 stops).
This unique filter combines the advantages of a polarizer with the warming effect of an 81A filter.
Circular polarizers are specifically designed for use with auto-focus SLR
cameras (They will also work on manual systems without
Neutral Density FiltersThese filters are designed to reduce the amount of light coming through your camera lens without changing the color. Neutral density filters can reduce the assorted colors of light in the spectrum. White and colored light is transmitted through these filters and only the intensity of the light is affected. These filters are used with black and white and color film. If you have set your camera to its fastest shutter speed along with the smallest f/stop, but still can't take the photo without overexposing the film, you can use one of these filters to reduce the exposure further. The filters help to eliminate bright, washed out sections of a photo. Neutral density filters usually range in price from about $10 to $350. They are available in various sizes.
B+W Neutral Density Filter 101 DIGITAL-PRO (ND 2)The lightest B+W Neutral Density Filter attenuates the light by one f-stop (log density 0.3), which can be beneficial, for instance, for the correct exposure of high-speed films when the brightness of the subject is still too high for the fastest shutter speed and the smallest aperture. It is recommended especially as a complement to B+W
Neutral Density Filter 102 for fine adjustments. The filter
factor is 2x.
B+W Neutral Density Filter 102 DIGITAL-PRO SLIM MRC
(ND 4) This B+W Neutral Density Filter reduces the light
by two f-stops (log density 0.6), and it 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 instead of a “frozen” waterfall. It has excellent
color neutrality, costs less than the denser filters, and is
recommended as part of a basic outfit. The filter factor is
Density Filter 103 DIGITAL-PRO SLIM (ND 8) Somewhat more difficult to manufacture and thus a little costlier, this B+W
Neutral Density 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.
B+W Neutral Density Filter 106
(ND 64)This B+W Neutral Density Filter reduces the light by six f-stops. With this filter and 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. Flowing water is rendered as flowing in the photo, and 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
B+W Neutral Density Filter 110 (ND 3.0) With a light intensity reduction of ten f-stops, this B+W Neutral Density Filter has a slightly stronger warm tone
than the ND 106. 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. The filter
factor is 1000x..
B+W Neutral Density Filter 113 (ND 4.0) With its light reducing capability of 13 f-stops, this B+W
Neutral Density Filter is used in astronomy for photographs
of the sun and for recording the relative movements of
heavenly bodies as light traces in extremely long exposure
times. For photographs of the sun, this filter must be
positioned in front of the lens and under no circumstances
should it be located near the primary focus in front of, or
behind the eyepiece because of the intense heat at those
locations. It must not be used for observation of the sun
(danger of blindness!) due to its greater transmission in
the infrared range. The filter factor is 10000x.
B+W Neutral Density Filter 120
(ND 6.0) With its light reduction capability of 20 f-stops, this B+W ND Filter is used for the same astro-photographic
applications as ND filter 113 when an even greater light
attenuation is required. In spite of its much higher
density, this filter too, must not be used for visual
observation because of its transmission
Graduated Color Neutral Density Filters -
Often, you want to balance light intensity between two areas within a scene This is important outdoors to allow more sky detail while properly exposing the foreground. Exposing for the foreground will produce a washed-out, over-exposed sky, exposing for the sky will leave the foreground dark and underexposed.
Graduated Color Neutral Density filters are part clear, part neutral density with a smoothly graded transition between. An ND.6-to-Clear is often best for balancing sky to foreground. The neutral gray appearance drops exposure.
B+W Graduated Filter Gray 501 The neutral gray half of
this filter transmits 50% of the incoming light, so that it
darkens the respective portion of the subject by one f-stop
without altering its colors. For example, when the sky is
too bright in relation to the landscape, this is an ideal
amount for good detail rendition in the clouds and for
preventing the sky from being “washed out” by over-exposure.
B+W Graduated Filter Dark Gray 502.
Because it attenuates the light twice as much as the
previous filter, i.e. by two aperture stops (it transmits
25% of the incoming light), this graduated filter al -ready
produces quite dramatic effects. Because of the increased
difference in brightness, it is even more important for the
horizon line not to be positioned too far from the center of
B+W Graduated Filter Red 590
This graduated filter is often referred to as the “sun -set filter”, because
it can simulate a missing red sky in the evening or in the
morning or to enhance one that is too pale when the line of
sight is towards the sun. By the sea or by a lake, the
horizon line should be positioned high enough for the red
portion of the filter also to cover the reflection in the
B+W Graduated Filter Orange 524
The somewhat more delicate coloring of this graduated filter is recommended
when the correction of the sunset mood is not to be too
pronounced, or when a certain amount of red coloring is
already present, so that only a small enhancement would be
sufficient. With heavy gray thunderstorm clouds it can
produce a nearly awesome storm mood.
B+W Graduated Filter Violet 543
With grazing light and a sparse exposure, this graduated
filter with its somewhat unnatural color can produce a
ghostly, macabre moonlight effect. So it is more suitable
for abstractions rather than enhancements of natural moods.
An interesting effect can be achieved by using it in
combination with the graduated green filter 56¡ for the
lower half of the image.
B+W Graduated Filter Tabac 550
Those who have experienced a sandstorm in the desert will
never forget that mood. With this graduated filter, one can
approximate that mood: slightly threatening, yet still
pleasantly “warm”. The tobacco color is discreet, not overly
colorful, so that it never appears gross nor overlay the
existing colors as much as the other more intense graduated
B+W Graduated Filter Green 561
Because of its vegetation color, this graduated filter is especially suitable for the lower half of an image when used in combinations with other graduated filters that are being used to darken or to alter the color of the sky. With such filter combinations, the TTL
exposure metering should be performed C
This is an excellent solution when the sky isn’t blue enough. It can be used effectively in combination with another graduated filter for the lower half of the image, so that in such a combination the sky will not be rendered too brightly or too pale. Example: sand dunes by the sea; using a graduated B+W Tabac
Filter for the lower half and a graduated Blue Filter for
the upper half of the image.
Color Conversion Filters
These filters are used to balance the color temperatures when you are using certain films under different light sources. An example of this would be using daylight film under tungsten lighting or vice versa.
Color conversion filters are designed to convert the temperature of the film to light or of the light to film. This will allow all the colors to fall in proper perspective and look natural. These filters are generally available in two series:
B+W 81A Warming Color Conversion Filter. Increase the
color temperature slightly; this can also be used
when shooting tungsten type B film (3200 K) with
3400 K photoflood lights. Pale orange color. The
opposite of 82A.. This filter balances color
temperature from artificial light sources to the
color tungsten film standard of 3200 degrees and
balances the difference up to 3400 degrees. Due to
this characteristic, a noticeable warmer color
reproduction is produced. This fine balancing is
important for special work such as art reproductions
where true color reproduction is required. Filter
factor is approximately 1.2.
B+W 81B Warming Color Conversion filter. It's Autumn. The clouds are low hanging and the sky is "patchy blue". You've gone for a ride upstate to the mountains and the light in open shade is bluish. A photo taken of your girlfriend with daylight balanced film leaning against the side of a barn will yield bluish tones that she might not find particularly flattering.
An 81B filter will replace even more yellow than an 81A and bring her skin tones back to a more appealing level. An 81B can also be used with electronic flash to reduce the amount of "blue" generated by the flash. The 81 series (81A, B, C, D and EF)
allows you to choose how much warmth you wish to replace in the image.
81C Warming Color Conversion Filter (KR3) ,
slightly stronger than 81B, opposite of 82C.This filter is
strongly recommended for daylight photographs, especially in
spring and summer with cloudless skies and clear air. It
helps eliminate the strong blue tone and haziness that is
produced by this level of ultraviolet light. Furthermore, it
will reduce the unwanted blue tone in shadow areas with an
overcast sky. Filter factor is approximately 1.2.
81D Color Conversion Filter
This filter controls the bluish coloration that affects daylight film. An 81D is used as a warming filter to eliminate the bluishness of open shade on very clear days. The 81D is stronger than an 81C and is also used for general landscape photography on cloudy days as well as to add more of a "suntanned look" in portrait photography.
An 81D filter will more than replace the yellow missing from the image and place all skin tones on a "warmish" level. The 81 series (81A, B, C, D and EF)
allows you to choose how much warmth you wish to
replace in the image.
B+W 80A (KB15) Color Conversion Glass Filter.
The slightly denser KB ¡5 filter is recommended for daylight
color reversal film with artificial light from the popular
60 to ¡00 watt halogen bulbs commonly used in lights aimed
at the ceiling. With weaker incandescent bulbs, there will
again be that pleasant warm tone for moody interior
photographs. Its filter factor is approximately 2.2.
B+W 80B B+W Color Conversion Filter KB 12 SLIM MRC
The deep blue filter KB ¡2 blocks so much red, orange
and yellow that it increases the color temperature of very
bright halogen and special photoflood lamps (of around 3400
K) to that of daylight. With that kind of illumination, and
with daylight color reversal film, the subjects will be
reproduced in their original colors. With weaker halogen
bulbs or stronger incandescent bulbs in conjunction with
this filter and with daylight reversal film, a residue of
“warmth” will be retained for an optimal mood in interior
photographs. Its filter factor is approximately 2.
B+W 80D (KB 6) Cooling Color Conversion Glass
Filter. This nearly medium blue conversion filter neutralizes the strong red tendency of light at sunrise or sunset out in the open when the original colors of the subject are wanted instead of a warm morning- or evening mood. In addition, the KB 6 filter is ideal for “under-corrected” filtering of artificial light photographs on color negative films. When filtration is performed only later during printing, there is a visible color shift, and full correction leads to a higher loss of light. Its filter factor is approximately
B+W 82A - Color Conversion Glass Filter
(KB 1.5)is a light balancing filter used to increase the color temperature slightly for a cooler tone. This blue filter absorbs the excessive yellow-red light from daylight in the morning.
There is much flattering light to be found in the early morning and afternoon hours. With sunlight low on the horizon, the red-orange end of the spectrum becomes enhanced. With daylight balanced film, images shot in this light may prove to be a bit on the warm side. The photographer may desire this effect or choose to "cool" things down.
An 82A has a greater "cooling" effect than an 82 but less than an 82B. The 82
series of blue filters allows the photographer to keep skin tones somewhat
normal by increasing the color temperature to a more daylight balanced level. In
addition, an 82A provides a cooler effect with tungsten film under 3200K lamps.
• 82A Increases temperature from 3,000 to 3,200 Kelvin (1/3 stop).
82B Cooling Filter These are light
balancing filters used to increase the color
temperature slightly for a cooler (bluer)
tone. Corrects the tendency toward reddish
tones. These series filters are also used to
prevent the reddish tones in early morning
or late evening light for natural skin
tones. - 2900 K to 3200 K - • 82B Increases
temperature from 2,900 to 3,060 Kelvin (2/3
Conversion Filter (KB 3) - With about twice the
correcting effect of the previous filter, this
conversion filter removes the orange-red color cast
that appears on photographs made on tungsten
reversal film with artificial light using 100 to 2oo
W light bulbs, or from aged photoflood lamps.
Therefore this filter is ideal for neutral color
reproduction with approximate illumination. • 82C
Increases temperature from 2800-3200 Kelvin (2/3
B+W Conversion Filter KB 20 SLIM MRC
This is the correct filter when the illumination is provided
by 40 to ¡50 Watt household incandescent bulbs, and the
transparencies are to show the subject in its original
colors (e.g., technical interior, architectural photographs,
or reproductions). It should not, however, be used for moody
interior pictures because unlike the KB ¡5 and KB ¡2
filters, the KB 20 filter corrects the light to a neutral
balance, eliminating the warmth that we might intuitively
expect from bulbs. Its filter factor is approximately 2.7.
Special Effects Filters
There are many types of filters available that are designed to give your photographs special effects. These include filters for special color effects, star effects, spectral effects, soft effects, mist effects, multi image and multi exposure effects, graduated color, dual color and tricolor effects along with spot filters, center filters and other special effects filters. These filters are mainly made out of glass and enable you to experiment with your photos or give them specific effects. The filters are available in various colors, sizes, styles and densities. If you buy extra filters you definitely require a good camera bag with padding to hold and protect them. They generally range in price from about $20 to several hundred and many of these filters are sold individually or in sets.
4x Cross Screen 684 Star Effect Glass Filter
The star patterns created around light sources by star screens are not
spread out as colorfully as those created by Spectra
attachments. Instead, their colors are less pronounced. The
rays begin right at the light sources, they are very long
and they are most effective when they are not vertical and
horizontal, but at an angle of approximately 45° to the
B+W 6x Cross Screen 686 Star Effect Glass Filter
The star pattern produced by this screen is similar to that of the previous one, except that it generates 6 beams from light sources and reflections at an angle of 60° to one another. Here too the light rays ema

Soft Focus FiltersDiffusion filters are used to create soften images.
A diffusion filter diffuses strong light without affecting the sharpness and contrast of the image. Thus, it is different from the effect of out of focus. Diffusion filters are mainly used in portrait work. In general, small skin defects can be eliminated almost completely, and facial contrast and wrinkles are soften. To create a better result,
the aperture should be opened up so that the subject can stand out well against the background
|Soft does not mean unsharp
In spite of the fact that the effect of soft focus attachment is related to unsharpness, it should not be equated with it. That is because good soft focus attach
-ments only “coat” a so-called core image that remains very sharp with a subtle veil of unsharpness, so that soft-focus photos can be rich in details. It is exactly this delicate combination of approximately 70% to 90% sharp with only ¡0% to 30% of an unsharp blend that creates its pleasant charm.
In some types of soft effect filters, there is a noticeable reduction of contrast that results partly from refraction and partly from light scattering by the struc
-ture of the surface. This can make a contribution to the soft focus effect that is at least equal to that of the finely coated veil of unsharpness.
It’s better to over-expose
In descriptions of the effects of soft focus attachments, reference is frequently made to flare, light fringes or halos. That implies that the subject is bathed in light. The friendly effect of such soft focus pho
-tographs also has something to do with our fondness for just the right amount of pleasing light.
That amount of light can only appear authentic if the picture’s light-colored portions are really bright. That in turn means that the original exposure should not be too dark, but preferably a bit over (by approximately
B+W Soft Focus Attachment Soft Pro
Glass Diffusion Filter. The effect of this B+W soft focus attachment is cre
-ated by fine lenticular protrusions that have been applied to a high-grade plano-parallel plate of glass in a random pattern. The light passing through between these protrusions creates a sharp core image for ac
-curate focusing and great detail. This is an important feature for photographers using AF reflex cameras. The light diverted from its regular direction by the mini-lenses, coats the image with a diffuse halo of light for a delightful softness. This soft focus attach
-ment is as ideal for feminine portraits, especially with highlights in blond hair. You can also use this attachment to create dreamy landscapes.
B+W Soft Image Glass Filter. Subject contours “flow” markedly softer with the Soft Image attachment on the lens than they do with the B+W
Soft Pro. Prominent halos form around light sources and
reflections, and bright parts of the subject acquire a
noticeable veil of light. This effect is maintained even
when the lens is stopped down. It is recommended for
portraits and for backlit situations (however, it may be too
soft for some landscapes).
B+W SF Attachments Original Zeiss Softar
1 and 2
This soft focus attachment has a large number of mini-lenses of varying sizes distributed on its surface in a random pattern, which deliberately defocuses the light that is passing through. This creates a soft, unsharp image around a sharp core image (which is advantageous for reliable manual or automatic focus
-ing). The soft focus effect is largely independent of the chosen aperture setting, so that the depth of field can be controlled for the most part with only very modest concern for the degree of the soft focus effect. For a delicate soft focus effect, there is the Softar
1, and for a more pronounced soft.
B+W Fog Attachments Fog 1 and Fog 2
The effect of the Fog ¡ and Fog 2 attachments is quite different from that of the soft focus attachments as descibed above. The subject appears to be behind a delicate, bright veil of fog, which, unlike the effect created in corresponding pictures by soft focus at
-tachments, also noticeably lightens large dark por
-tions of the picture. All colors are strongly whitened and desaturated. By slightly over-exposing by ap
-proximately half an aperture stop, the romanticizing soft
effect can often be enhanced even further. The two strengths
that are available serve for tailoring the effect to the
The Softspot attachment consists of a clear circular opening in the center, surrounded by a structured surface that “coats” the outer portions of the image with a whitening unsharp softness in a vignette-like fashion: the center of the image is clearly emphasized and surrounded by a wide frame. At large apertures (small f-stop number), the transition from sharpness to whitened unsharpness
is very gradual, whereas it is almost abrupt when the lens
is stopped down. It is advisable to use the preview lever on
cameras (that are equipped with one) to determine the
B+W Color Enhancing Filters
B+W 491 Enhancing Filter The B&W
Enhancing Filter is an absolute necessity for those who
enjoy the Autumn foliage or any venue where you wish the
earth tones to be exaggerated. This filter gives the red end
of the spectrum a "boost" creating colors that are more
vivid, saturated and surreal. It is a combination of rare
earth elements (didymium) in glass. It removes a portion of
the spectrum in the orange region, increasing the color
saturation of reddish objects by eliminating the muddy tones
and maximizing the red hues with minimal effect on other
colors. The filter ring is made from brass yielding a
stronger product. Brass filter rings are also less prone to
jamming. In addition, the seal between the glass and filter
ring is exceptionally strong giving the filter added
strength and durability. The excellent Schott Glass used in
the manufacturing of this filter is legendary and synonymous
with the highest standards of filter production. It comes
with a solid 10-year warranty. • Its most frequent use is
for obtaining strongly saturated photographs of Fall foliage
• Use with polarizer for more dramatic effects.
B+W 491 Enhancing Filter (Slim) This filter uses a slim line mount. Slim filters are only 3mm thick and are specifically designed for use with lenses as wide as 17mm in the 35mm format. In order to help eliminate vignetting
(darkening of the corners), they do not have a front thread.
It comes supplied with a slip on lens cap.
Fluorescent filters are used to correct the greenish tone that can show up when you are shooting daylight film under fluorescent lighting. There are various types of fluorescent filters. They can balance daylight film under warm white or white type fluorescent lights and correct the color balance when using tungsten film under fluorescent lighting. Fluorescent filters are basically general purpose filters that are designed for moderate correction. They may not always provide perfect color rendition by themselves. Because fluorescent lights shine at various temperatures they often need more filtration for proper results.
B+W #499 Fluorescent Glass Filter for
Daylight Film This B+W Special Filter eliminates the
green cast that occurs when daylight-type color film is in
fluorescent lighting. Examples are interior photographs made
in offices, reception areas, factory halls, subway stations
and swimming pool halls, as well as night-time photographs
of office buildings whose windows would appear green because
their interiors are usually illuminated with fluorescent
tubes. The abbreviation F-Day stands for “Fluorescent Light
- Daylight”, which reflects the fact that these filters are
designed for the most commonly used type of fluorescent
tube, which emit light of a color that, as mentioned above,
resembles daylight. Because fluorescent tubes are not
“thermal radiators”, they do not produce a continuous
spectrum like those of the sun and incandescent bulbs.
Instead, they emit a sharply defined line spectrum that has
high intensity spikes in the green region. Our eyes barely
perceive this special green, so the fluorescent light
appears to us as nearly neutral in color. However, most
color films are especially sensitive to those wavelengths
and they react with a strong pronounced cast. Photographers
using color temperature meters for three color metering
(simple meters that measure only two colors are not suitable
for this purpose) can also undertake the correct filtering
with of a combination of LB- and CC filters (see pages ¡7 -
23). With this method, they can also correct the light
emitted by other types of fluorescent tubes, such as Warm
Tone, Standard Light, White Light, etc. But for hobby
photographers who do not wish to make a large investment in
such an instrument and who do not care to carry along a
selection of LB- and CC filters, the B+W F-Day Filter is far
less expensive and much.
B+W KR12 Color Conversion Glass Filter
This B&W KR12 Reddish-Brown Color Conversion Glass
filter allows the use of a tungsten-balanced film in
daylight without a strong blue cast. It effectively absorbs
the excess of daylight blue that is otherwise superimposed
on all the colors. But, the KR12 filter is not only useful
as a "savior in cases of need", or for making good use of an
otherwise useless remnant of film, because it can also be
used effectively for overcoming extreme contrasts that are
greater than a daylight reversal film can handle. A reversal
film balanced for tungsten light has a flatter gradation
curve, adding a possible high contrast control. Note!
Whereas the 85 series is used for tungsten film under
daylight conditions, use the 80 series of filters when using
daylight film under tungsten lighting 85 Series Color
Conversion Chart • An 85 decreases the color temperature
from 5500-3400° Kelvin • An 85A decreases the color
temperature from 5500-3100° Kelvin • An 85B decreases the
color temperature from 5500-3200° Kelvin • An 85C decreases
the color temperature from 5500-3800° Kelvin.
|Black & White Photography Filters
Filters are often used in black and white photography as black and white are actually produced as tones of gray. Filters are used to make the gray tones look like the original scene.
The sky and clouds often blend together in black and white photos as white, so filters are used to separate the two. A red filter can darken blue objects more than white objects. So if you use this filter the sky will look black in the photo and the clouds will still be white.
More differentiated greens
Why does the use of a yellow-green filter lead to a much
better differentiation of green tones in nature- and
landscape photography? Here is the answer: Green can be a
spectrally relatively pure green, but it can also be a
blue-green & yellow-green mixture. Whereas pure green is
readily transmitted by a yellow-green filter, an equally
bright mixed-color green will have its blue-green component
reduced, so that it will appear darker in a black-and-white print, darker than the gray tone generated by pure green.
Brightness- vs. color contrast
Unlike color photographs, black-and-white photographs only have brightness contrast, no color contrast. That is why in the photography of objects, for example, things that have different colors but the same brightness will have similar gray values. For instance, when there is a blue toy in the foreground and red dress with the same brightness in the background, they will be reproduced with the same gray values. This is referred to as insuffi
-cient tonal separation.
Colored filters are helpful in such situations. First the photographer must de
-cide which object is to be rendered lighter and which one is to be rendered darker. Then he can select a filter color that ¡) is similar to the color of the object that is to be shown lighter and that 2) is as com
-plementary as possible to the object that is to be rendered darker. If the two colors are already nearly complementary, like blue and orange, he selects a filter color that is similar to that of the object that is to be rendered lighter. If the two main colors are not complementary, like blue and red, a compromise can be used: A blue filter lightens the blue color, but it also darkens the red color a little. But a green filter could also be used. While it would only lighten the related blue color a little, it would darken the red color more strongly than the blue filter would. The photographer would have achieved his objective in either case: a good tonal sep
-aration with the lighter gray of the toy and a darker gray for the dress.
B+W 021 Light Yellow Glass Filter
This filter suppresses violet and attenuates blue. On the other hand, green,
yellow, orange and red are reproduced in lighter shades. It
is ideal for landscape photographs, since white clouds will
contrast more against the darker blue sky, and the shades of
green on plants are more differentiated. Freckles and skin
blemishes in portraits can be attenuated, tans can be
rendered lighter. Its filter factor is approximately 1.5.
B+W 021 Light Yellow Multi-Resistant Coating
(MRC) Glass Filter. Commonly used for an increase in
contrast with black and white films. There are occasions
when your image needs a subtle nudge - something to bring
the contrast up
B+W 022 Medium Yellow (8) Filter.
With stronger blue suppression, which extends into the
blue-green, the effects described above are slightly
stronger in the same types of applications. Clouds in the
sky look very natural, but not yet dramatic. Distant views
with light haze become clearer. An ideal filter, especially
for landscape- and plant photographs. Its filter factor is
B+W 022 Medium Yellow (8) Multi-Coated (MC)
B+W 023 Dark Yellow (9) Glass Filter
(For Clouds) The even greater blue suppression and the
attenuation into the blue-green range leads to a further
increase in the effects described above. Interesting for
snow scenes under a blue sky, because the darkened blue
shadows in the snow make the shapes of the landscape look
more dimensional. Freckles and skin blemishes are diminished
strongly, but lips are rendered more pale (to compensate for
you may use a dark lipstick!). Its filter factor is
B+W 023 Dark Yellow (9) Multi-Resistant
Coated (MRC) Glass Filter.
B+W Bay 3 040 Yellow-Orange (16) Glass
B+W 040 Yellow-Orange (16) Glass Filter. The effect of this filter is quite powerful. It darkens violet and blue very strongly, green strongly, it even darkens yellow-green a bit. Landscape- and architectural photographs have an increased, virtually “graphic” contrast, clouds in the sky already look dramatic. Because skin tones are strongly lightened in relation to the green tones of plants, this is a favored filter for nude photography outdoors, because it raises the contrast between the lighter bodies and darker landscapes. Its filter factor is approximately 4.
B+W 040 Yellow-Orange (16) Multi-Coated (MC)
B+W 041 Red-Orange (22) Glass Filter
B+W 041 Red-Orange (22) Multi-Resistant
Coated (MRC) Glass Filter. The intensified effect of
this filter borders on the abstract. It darkens a blue sky
with clouds to resemble the mood of an impending
thunderstorm. Architectural photographs gain clarity and
drama. This filter is also interesting for many
black-and-white close-up photographs of flowers, when dark
yellow, orange or red blossoms have almost the same
brightness as the surrounding greenery: This filter is used
to render the flowers in lighter shades of gray. Depending
on the subject, its filter factor is 4 to 5.
Black & White Film Contrast Filters
B+W 60 Yellow-Green (11) Multi-Coated
(MC) Glass Filter This B&W 060 Yellow-Green Glass Filter Multi-Coated (MC) has an effect similar to that of the medium yellow filter, but it also darkens red colors. Clouds in the sky gain more contrast. A red roof and red flowers are rendered darker in relation to plant greens (as they would not with a purely yellow filter). The yellow-green filter accentuates the delicate springtime green in nature. It makes portraits more dramatic.
Multicoated toMinimize reflection at the filter surfaces which reduces flare and ghosting.
• Especially suited to landscape photography because it enhances the light green color of the leaves
• Due to its favorable effect on red tones, it is also suitable for portraits against the sky
• Universal asset for all scenics • Darkens sky in contrast to clouds.
B+W 061 Dark Green Glass Filter
This B&W 061 Dark Green Glass Filter differs from the Yellow-Green filter primarily because of its increased red attenuation. A red roof or red flowers will become even darker, as will red lips and a dark tan. Unfortunately, so will skin blemishes.
This filter is ideal for nature photography. In object photography, it is good for darker reds and lighter greens.
• Especially useful for clear contrast between blue sky with clouds and foreground
• Recommended as a basic filter for use with Kodak Aero Ektachrome Infrared
B+W Bay 1 090 Light Red Glass Filter.
and White Film. for contrast effects, darkens sky and water,
B+W 090 Light Red (25) Multi-Resistant Coated (MRC)
This B&W Light Red Multi-Resistant Coated (MRC) Glass Filter is the classic
filter for strong contrast in black and white and
architectural photography. The white sides of buildings
shine brightly; skies are darkened dramatically and clouds
become more impressive. It is also excellent for spectacular
landscape photographs that will be characterized by greatly
improved vistas. Multicoated to minimize reflection at the
filter surfaces which reduces flare and ghosting. • Clouds
are dramatically improved almost to the mood of a
thunderstorm; darkens blue sky creating dramatic contrast
between sky and clouds • It is more effective in cutting
through haze, and moonlight effects are easily accomplished;
creates greater contrast between foliage and flowers • It is
also suited for infrared photography 1.
B+W 091 Dark Red (029) Glass Filter.
Ideal for strong contrast improvement since it absorbs green
and blue completely and enhances red. In addition to
contrast control, red filters enhance skin tones, tonal
corrections and are effective for more dramatic landscapes.
B+W 091 Dark Red (029) Multi-Coated (MC)
Glass Filter. Compared to the B&W Light Red filter
(090), this B&W 091 Dark Red Multi-Coated (MC) Glass filter
darkens the reds near the yellow tones in the spectrum, as
its transparency only begins in the orange-red region. It
produces dramatic effects and extreme tonal separation for
graphic effects. Multicoated to minimize reflection at the
filter surfaces which reduces flare and ghosting. • Stronger
than an 090 Light Red (25) • Clouds are dramatically
improved almost to the mood of a thunderstorm; Darkens blue
sky creating dramatic contrast between sky and clouds • Use
with Polarizer for dramatic black and white effects • It is
more effective in cutting through haze, and moonlight
effects are easily accomplished; Creates greater contrast
between foliage and flowers • Used in scientific photography
• Excellent copying filter for blueprints.
Infrared filters are made to block mid infrared wavelengths while allowing visible light to pass through. They are sometimes referred to as heat absorbing filters and are ideal at cutting through haze. These types of filters are commonly used to prevent unnecessary heating in items which have bright incandescent light bulbs. Examples of such devices are slide projectors and overhead projectors. You can also get near infrared filters. These types of filters commonly are used in video cameras to compensate for the high sensitivity of the camera's sensors to near-infrared light. Infrared filters can range in price from about $20 to $450. They come in various sizes, styles and brands.
Infrared Filter 092 (≈ 89 B) [RG 695]
The nearly opaque B+W Infrared Filter 092, which looks dark purplish red when held in front of a light source, blocks visible light up to 650 nm, and passes only 50% of the radiation just below 700 nm (thus the dark red color). From 730 nm to 2000 nm, transmission is greater than 90%. This makes photographs of pure red and infrared images possible with the best utilization of the relatively low sensitivity of infrared films. As the sensitization of infrared black-and-white films barely extends beyond 1000 nm, the red portion that is transmitted still makes a relevant contribution to the exposure. That is why this filter is the preferred filter for pictorial photography on IR
black-and-white film. Its filter factor is 20 to 40.
Infrared Filter 093 (≈ 87 C) [RG 830]
This B+W Infrared Filter blocks the entire visible spectrum, so to our eyes
it looks completely opaque. Unlike the infrared filter
described above, it makes pure infrared photographs possible
without the visible red component. Its transmission only
begins to exceed ¡% at 800 nm, rising to 88% at 900 nm, and
remains that high far beyond the upper limit of
sensitization covered by infrared films. This filter is used
less frequently in pictorial photography because of the
dramatic loss of effective ISO. But in the scientific field,
materials research and forensics, the limitation to a
strictly infrared range is often important. The filter
factor is very dependent on the illumination and on the
characteristics of the film.
Infrared Filter 099 (≈ 16) [OG 550]
The orange-colored B+W Infrared Filter 099 is the ideal filter for
photography with infrared color film, which is also referred
to as “False Color Film” because of its charming abstract
color reproduction. It blocks large portions of short-wave
radiation, up to 520 nm (blue, blue-green) and reaches its
full transmission near 600 nm, which it retains far beyond
the sensitization range of these films. This avoids the blue
cast that is caused by the heightened sensitivity in this
spectral range, and it leads to a better differentiation of
colors. The charm of these infrared color photographs is
partly due to the orange to red rendition of green
vegetation, which is due in turn to the high infrared
reflectivity of the chlorophyll in plants. The filter factor
is highly dependent on the film.
B+W 489 Infrared Glass Filter This IR-blocking filter must not be confused with heat-resisting protection filters for projectors or spotlights. Instead, it is intended for use as protection for IR-sensitive CCD sensors or in the light path of illumination devices with low thermal characteristics. It suppresses infrared radiation ≥780 nm. Because it gradually begins to absorb infrared radiation at 600 nm, long-wave red light is slightly weakened, so that this filter has a subtle green tint. But in CCD
applications, this can be readily corrected electronically.
Its filter factor is approximately 1.2.
