Bergger BPF 200 Film And Prestige Paper
By Tom Fuller February, 2000
| |
Prestige Variable CM, one of several pleasantly stout
fiber-based papers manufactured in France by Bergger,
has a richness and luminosity that has almost become a
thing of the past. For those who like really thick prints,
Prestige Silver Supreme is coated on an extra premium-weight
100 percent cotton rag stock.

As French-made Bergger black
and white film and paper meet virtually every requirement of the exacting
large format worker, “Fine Materials for Fine Photography”
would also be a suitable title. Bergger BPF 200 film, available in a
wide range of standard and specialty sheet sizes, is a very close replacement
for Kodak’s much-missed Super XX. Pair it with the dense blacks,
gentle tonal gradation, and thick base of Bergger Prestige, a line of
silver-rich papers able to hold their own against any premium offering
on the market, and you have a combo that impresses even those of us
who remember when Kodachrome came in red--or was it yellow--metal cans.
Like Kodak Super XX, Bergger BPF 200 provides a nearly straight-line
density gradient that allows wide exposure control with almost any developer,
a particularly endearing quality to Zone System practitioners who expand
and contract scene values on a picture-by-picture basis. The panchromatic
emulsion offers good resolving power, exceptional exposure latitude,
and linear color sensitivity, the last making BPF 200 an excellent choice
for dye transfer and color separation work. In everyday pictorial photography,
this linearity translates to accurate gray-tone rendering of blue skies
without a yellow filter over the camera lens.
BPF 200 has been called a “thick emulsion” film, a misnomer
for the traditional design in which hunks of silver halide are suspended
in a single gelatin layer. Unlike newer approaches that use multiple
layers and/or platelet-shaped particles, “old technology”
manufacturing relied only upon particle size to determine film speed.
The advantage is that these emulsions work well with many developers
and processing methods, including pyro, for maximum creative flexibility.
While the grain of such films may be slightly coarser than that of new
ones, the small degree of enlargement required of large format negatives
makes this of consequence only to 35mm and medium format users.
In my tests BPF 200 came through with flying colors, being able to record
an exceptionally wide subject brightness range with normal development
at its labeled speed. The film is rated at ISO 200, a figure that proved
to be a good starting point for producing brilliant negatives with excellent
shadow detail using tray development for nine minutes in Kodak D-76
(1:1) at 68°F. The manufacturer’s starting points with other
soups are 4.5 minutes in Kodak HC 110 (Dilution B), 18 minutes in Rodinal
1+50, and 6.5 to 11 minutes in PMK Pyro. Reciprocity correction is not
required for exposures from 1/1000 to 1/2 sec.

BPF
200 did a respectable job of capturing detail in the shadow
and highlight areas of this scene.

BPF 200 is coated on a 175 micron
polyester base and produced in 4x5”, 4x10”, 5x7”, 8x10”,
8x20”, 7x17”, 14x17”, 12x20”, 20x24”, and
30x40cm, with other sizes available from the factory upon special-order
request. The securely packaged film is interleaved with thin semigloss paper
that is very difficult to detect even with bare hands, so use care when
loading so as not to insert a sheet into the holder with its protective
sheet on top.
Designed by the former chief chemical engineer for Guilleminot and Boespflug
of France, fiber-based Bergger Prestige paper is available in double weight,
premium weight (300g/m2), and, with Prestige Silver Supreme, an extra premium
weight (320g/m2) base. Except for Silver Supreme, these silver-rich papers
are offered in neutral and warm tone, graded and VC, and in standard sizes
from 8x10” to 20x24”, including 12x16”. Silver Supreme,
produced only in 40x50cm and one (Normal) contrast grade, is coated on an
exquisite 100 percent cotton rag base.
Prestige NB is a double-weight glossy neutral-tone bromide paper, with Prestige
NM having the same bartya-based emulsion in matte finish. Both are available
in grades 1 to 4. Prestige Variable NB is a double-weight glossy neutral-tone
VC paper that responds to Kodak and Ilford filters, or the corresponding
values set on a dichroic or VC enlarger head. Prestige CB is a double-weight
glossy warm-tone chloro-bromide paper, with CM having the same emulsion
on premium-weight stock. Both are available in grades 2, 3, and 4. Prestige
Variable CB (glossy) and CM (semimatte) are warm-tone premium-weight chloro-bromide
VC papers, with Prestige Silver Su-preme’s bromide emulsion giving
a neutral, semimatte image.
Prestige exposure times were a little on the long side, but the paper is
by no means what I would call slow. I experienced some fogging with a yellow
(OC) safelight, so I recommend taking the manufacturer’s advice and
using a red (1A) filter in a dim fixture. Of course, my original filter
may have been defective, but I had no further trouble with a 1A in the same
unit. Almost any developer works well, but I found 21/2 minutes to be a
good starting point in Dektol 1+2 with graded and VC versions. Two minutes
in 1+40 selenium gives the image a nice, gentle tone, but the possibilities
are almost endless by varying toner dilution and/or treatment time.
Finding the words to describe a good image is like finding ones to characterize
a fine wine, but to put it simply, Prestige is an exquisite paper. The blacks
are bold, the base is bright, and the image possesses a unique “depth”
that is seldom seen today. While I can’t yet defend this with facts
and figures, I believe it is simply the “old” design of its
emulsion--the absence of brighteners, topcoats, incorporated developing
agents, and other additions common to “new” papers--that gives
Prestige this distinctive quality. Prestige paper and BPF 200 film are fine
traditional materials for the discerning photographer who, young or old,
can savor the visual feast offered only by a meticulously executed black
and white photograph.
