Particularly in digital photography, B+W
fi lters are important tools for improving
image quality. A B+W polarizing fi lter,
for example, provides more saturated col-
ors and higher color contrasts because the
bluish-gray haze typical of sunny days is
fi ltered before the image sensor gener-
ates the data record. If UV or IR radiation
causes haze or blur a UV/IR blocking fi lter
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 remov-
ing image information (destructive image
correction). Such, in some cases coarse
repairs leave considerable gaps in the
data record which are not yet recogniz-
able on the PC monitor, but can become
visible on the higher-resolution print.

A key criterion for an outstanding fi lter is
the coating. Quality begins in front of the
lens, and that is, of course, where the
fi lter is placed. A fi lter 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 refl ection reduction
and thereby eliminates disruptive stray
light. In this way, more brilliant colors and
higher contrasts can be attained. Due to
the low residual refl ection (0.5%) MRC re-
liably prevents ghost or multiple images
which can be caused by back refl ection
from the image sensor.

Furthermore, MRC protects the fi lter from
scratching with increased layer hardness,
thereby preserving the high optical quali-
ty. In addition, MRC is dirt and water
repellent, which makes cleaning easier.

NEW: The MRC nano coating – all XS-Pro
Digital fi lters 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 fi lter surface even simpler
and faster.

Top performance thanks to
Multi Resistant Coating (MRC)
Multi Resistant Coating (MRC)
B+W is the fi rst fi lter 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 low-refl ec-
tive and highly resistant to scratching. But
above all its unique dirt and water-repel-
lent surface makes cleaning the fi lters
easier. In this way, fi lters can also perform
a protective function for the front lens.
