First Exposure by Larry Brownstein
B+W Digital Filters
I have a feeling that in this digital age
photographers are using fewer optical filters. That would
not be too surprising considering the ease with which images
can be adjusted in Photoshop. Certainly it is no longer necessary
to use color correction filters, such as FLD, 80A and 85,
since digital cameras have built-in white point balancing.
But I’ll bet it goes way beyond that. Whereas once
photographers would turn to optical filters for creative
effects, they are probably now using digital filters instead.
There
are probably thousands of digital filters available, and
I have experimented with many of them. Some of them are a
barrel of fun—MetaCreations KPT Vortex Tiling comes
immediately to mind. It takes a source image and warps it
into a swirling vortex of distorted replicas. Some filters
are very practical such as Digimarc filters that embed and
read watermarks in a digital image. There are many filters
that simulate artistic effects such as Photoshop’s
native Watercolor filter.
It has seemed to me that what was
missing were software filters equivalent to the optical filters
that have for a long time been popular with photographers—Polarizers,
graduated neutral density filters, 81-series warming filters,
and soft-focus filters. B+W is a name many photographers
recognize as a manufacturer of premium optical filters. That
is why I was eager to look at the new offerings from B+W
Digital Imaging. As a manufacturer of optical filters, I
reasoned, they would likely be sensitive to this need.
B+W
packages the filters into two sets: the Outdoor Set and the
Portrait and Family Set. The Outdoor set contains these filters:
Brighten, Graduated Blue, Graduated Neutral Density, Polarizing
Enhancer, Summertime and Warming. The Portrait & Family
Set contains these filters: Black and White (cool), Enhance
Colors, Luna, Soft Focus, Summertime and Warming.
These filters
are standard “plug-in” filters.
They are compatible with Photoshop and other programs that
use the Photoshop “plug-in” standard, such as
Photoshop Elements and Corel Photo Paint. I used Photoshop
for my tests. In Photoshop, once the filters are installed
they are accessible from the Photoshop Filters menu with
a menu pick for each of the two filter sets. The individual
filters are found in the sub-menus.

I started my tests with
a picture of Bree in a wedding dress (Figure 1). It was taken
in a studio with four flash heads bouncing off of two large
white cards on both sides of her, creating very soft light.
The camera was positioned in between the white cards. I wanted
to exaggerate the feeling of this being an old photo (the
dress and the boa give a hint of this). Sepia toning is an
effect that many photographers use for this purpose. This
process is done on a finished black-and- white print. I wanted
to see if I could do something similar with the software
filters. I used the Enhance Colors filter and played with
the sliders until I got the understated effect I desired
(Figure 2). How nice to get a Sepia effect without the mess
and unpredictability of using chemicals!
Over the years I
have converted from an optical filter fan to a purist (what
you see is what you get). The one filter that I still occasionally
use is the Polarizer. I don’t
even use it much anymore because my favorite lens (a 17–35mm
zoom Nikkor) has a front element that is too large for most
Polarizers. Also, it is so wide-angle (at 17mm) that it would
vignette with most Polarizers (since they tend to be thick
filters). Furthermore, I keep the hood on this lens to prevent
lens flare, yet another thing that would interfere with successful
use of a polarizer. Also I tend to use the tripod less these
days so I can’t afford to lose the two f-stops that
a polarizer absorbs! As you can see, though I love how a
Polarizer can improve photos, I have had many reasons for
forsaking its use.

Could the B+W Polarizing Enhancer provide
the same rich, saturated colors that result from using a
polarizer? To find out, I used a picture of the Los Angeles
skyline that I like, which has some clouds against a vivid
blue sky (Figure 3). I shot this with a Mamiya 7 II 6x7 camera
with the panoramic adaptor that allows you to run 35mm film
through this 120mm camera. With the interesting clouds, I
thought this image would be a good test for the Polarizing
Enhancer. I played with the sliders until I got some nice
contrast between the clouds and the sky. I also got a slight
bit of warming, which can be seen in the light-colored building
on the right. Figure 4 shows the results of this filter.
In my opinion, it is much like the results off a conventional
polarizer. Quite impressive!
Back to the Portrait and Family
Set—I had an interesting
picture of Luba (Figure 5), which needed a little bit of
help. The picture was taken in open shade with a bit of flash.
This kind of light is nice and soft. The only problem is
that the light is a bit cool, since there is no direct sunlight.
Even if I had a warming filter available at the time, I wouldn’t
have used it because I was shooting at 1⁄60 second
and couldn’t risk any slower shutter speeds. I simply
used the Warming filter and added just a bit of warmth.

The
result is seen in Figure 6. You have to compare the two images
closely to even see the difference. But this is the kind
of subtlety that I am glad to have available from these filters.
If I had wanted a more noticeable effect, perhaps simulating
the effects of an 85 series filter, it was an option the
software made available to me by simply dragging the sliders
a bit more.
Lastly, I wanted to experiment with converting
a color image to black and white. I had this image of Pegah
(Figure 7), which I began to feel was a little over the top
with color. It was done in the studio with a ring flash illuminating
the model and a gelled flash head illuminating the background.
Between the colored gels and the colored beads I thought
it was too colorful, so I used the Black and White (cool)
filter, which did a pretty good job. However, seeing the
results I realized I wanted to bump up the contrast before
converting to black and white. I wanted to blow out some
detail in the face, and I wanted the black dress to stand
out more in the final image, too. I used the Luna filter
to add contrast, as seen in Figure 8. Then I used the Black
and White (cool) filter resulting in a beautifully contrasty
black and white image, as seen in Figure 9.
I tried all the
other filters in the sets, too. My two favorites are the
Polarizing Enhancer and the Warming filter. Besides freeing
me from needing to use conventional optical filters, they
are so easy to use!
B+W also provides some great user-interface
features. For example, the Preview window has a button to
enlarge (zoom-in) on the image, allowing me to see the effect
more easily. A Reset button is easily available to reset
the filter back to default settings. I find I use Reset often
when using filters. It allows me to play with the sliders
with no hesitation as I can easily get back to “home
base.”
What would I change? Well, first of all,
I would drop the silly “(cool)” from the name
of the Black and White (cool) filter. The Enhance Colors
filter was a bit too far out for my taste. It reminds me
of the wild, but not so useful, effects that one can achieve
simply by chopping the curve in Photoshop’s Curve command.
The Soft Focus filter actually seemed too subtle to me, I
couldn’t
see a difference after applying the Soft Focus filter.

On
the product packaging (backside) there are before and after
examples of one of the filters in the set. It would be
great if they showed a similar before and after for each
filter so the user can see their capabilities. It might not
fit on the product packaging, but a one-page insert would
be all that is needed.
While wild and crazy effects are possible
with these filters, the best thing about them is the subtlety
that they allow. Being able to use a software filter to warm
an image ever so slightly allows me not to worry about whether
I have an 81a, 81b or 81c filter on my lens. Now with B+W
Digital Filters it is even easier than using Photoshop’s
native abilities to do this.
The filter sets are available
for Windows and Mac OS X. Mac OS 9 is not supported. Under
Mac OS X only the following versions of software are currently
supported: Photoshop 7 and Photoshop CS, Adobe Elements
2.0, and Corel Photo Paint 11.0. There are fewer restrictions
on the Windows side. The B+W web site has more details:

Many thanks to models, Pegah Ghamary, Bree Victoria and
Lyubov Soluhabova for their efforts—L.B.
