high-resolution film and chemistry
is an ultra-high-resolution 35mm film and developer combination, originally formulated for
surveillance photography, identification, and documentation. It can be enlarged beyond
the resolution limits of your lenses without losing detail to grain.
unlike traditional high-resolution films, it has a beautiful, long panchromatic gray
scale and biting clarity.
Noted authority Geoffrey Crawley reviewed Bluefire Police in the July 11, 2005 issue of Amateur
Photographer, Great Britain's weekly photo magazine, and called
it "...an exciting new b&w material capable of

An excellent upgrade from Efke 25 or Agfa's discontinued AgfaPan APX25, with similar contrast but
much finer microstructure and significantly more speed. Less grain than T-Max 100 and Delta 100,
without the exaggerated edge effects associated with tabular grain films.

It is in regular use documenting DNA assays and making quick, inexpensive

Also gives excellent results with most
microfilms, and high-contrast 35mm document films.
This developer produces extremely low contrast
when used to develop ordinary black
and white films that have been conventionally exposed.
The 30-ml sample size has been pre-mixed
for your convenience and will process two rolls of film.
The 500-ml package is shipped as a
pre-mixed liquid concentrate in a collapsible pouch bag. You can easily
squeeze it to exclude air as you withdraw the concentrate, which
prolongs its shelf life after opening. It will process 33 rolls of film.
The 1-litre (approximately 1 US
quart) package is shipped as dry powder. Mix it with hot tap water to
make concentrate sufficient for processing 66 rolls of film.
Add 15ml of concentrate to 235ml of water to
make 250 ml (approx. 8-1/2 oz) of working solution, to
process one roll of 35mm film. Use the working solution once and then
with all ordinary stop baths and fixers.
HR's active ingredient (a form of phenidone) is sensitive to light and
moisture. In the 2-part powder package, it is heat-sealed into a
gas-barrier opaque pouch, which gives the dry, unopened product a shelf
life of many years. The liquid concentrate is packed in a flexible plastic pouch. The unopened pouch has a
multi-year shelf life. After opening, squeeze to exclude air and use
within one year. Discard if the developer begins to darken or turn pink.

Should you choose
dry powder or liquid?
life: dry powder in its sealed package has an almost indefinite shelf
life. Once mixed with water, its shelf life can be as short as a few days
unless the liquid is sealed away from contact with air. Properly sealed away from
refrigerated, it can be stored for several months, perhaps as long
as a year or two, depending on the quality of your tap water. Shelf life
of the mixed liquid is considerably longer if you make it with water that
has been boiled to de-aereate it, and have been careful to not introduce
air during mixing and pouring.
concentrate should be used within one year of purchase, to be absolutely
safe, but should have a shelf life of at least two years.
dry powder must be mixed in hot water, and can require prolonged stirring.
Liquid concentrate is used directly from the pouch bag, which can then
be squeezed to exclude air and re-sealed.
restrictions: dry powder can be shipped safely by any means. Liquid
concentrate is not hazardous, but since it is a liquid it may face
shipping restrictions, depending on your destination.
cost: Liquid is much heavier than dry powder and shipping costs are
Micro Developer for high-contrast document photography
Use this developer to process Bluefire Police
film exposed at
EI 80 to 100, for high-contrast images and personal microfilm applications.
The resulting image has solid blacks and whites, with little or no gray
tone. Grainless enlargement to as much a 4 feet by 6 feet is easily
achieved. Use any ordinary photographic stop bath and fixer.
Bluefire Micro's active
ingredient (phenidone) is sensitive to light and moisture. It is
heat-sealed into a high-barrier opaque pouch, which gives this unopened
product a shelf life of several years.

|Extremely fine grain
||Negatives can be enlarged to extreme sizes without
image degradation due to grain. In general, you will be able to enlarge
a 35mm negative to a degree beyond the power of your camera and enlarger
lenses to resolve detail, and still not lose detail to grain. Grain is
usually not apparent until 50x enlargement, and remains inconspicuous
even on enlargements at 4' x 6' (1.2 x 2 m).
||The film resolves extreme image detail. All images have an upper
limit to resolution — with Bluefire Police, that upper limit is a
function of the lenses used, and not of the film.
||The photosensitive emulsion is approximately half the
thickness of ordinary films, yet contains the same amount of silver. The
thin emulsion results in less internal light scatter, which improves
sharpness. High silver density yields images rich in tonal values when
correctly exposed and processed.

projection transparencies, photolithography masking, and technical

||When exposed at EI 100 and processed in high-contrast
chemistry, such as Kodak D-19 or Bluefire Micro, it yields grainless high-contrast images and is especially suited to use in
libraries and in the field by researchers and genealogists for materials
which cannot be photocopied.
When exposed at 80 and processed in
Bluefire HR developer, it
yields continuous-tone pictorial images with a rich gray scale, and is
especially suited to surveillance, engineering and research documentation, and art
records approximately the same portion of
the visible spectrum that is seen by the human eye. It has normal
panchromatic sensitivity to all colors, including red, so that its
effective speed is not changed by exposure in outdoor shade (which is
deficient in red wavelengths) or in normal indoor room lighting (which
can be either too red or not red enough).
