Bluefire high-resolution film and chemistry

 

Bluefire Police ™; 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. 

Scientists, engineers, and technologists value it for the extremes of magnification it makes possible.

However, 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 outstanding image quality, especially in the definition of the finest detail."
Your "Police film" works well with Contax CZ lenses. The coating 
and sharpness seem to do the film well.

Bluefire Police 135-24 35mm film, EI 80
Process in Bluefire HR Developer for pictorial photography, or Bluefire Micro for high-contrast photography (developers sold separately, below).  Item: BP13524

  6.49 per roll

  64.89 per 12 rolls, shipped free to North American addresses Item: BP1352412

 

35-24, 24-exposure for use in standard 35mm cameras. Set your camera manually to ISO 80 for pictorial use, or ISO 100 for high-contrast technical photography.

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, and with different image qualities.

Can also be processed for pictorial use in Adotec, POTA, Formulary TD-3, Kodak Technidol, Maco LP Supergrain, and similar ultra-low contrast developers (effective film speed will be lower with these developers). 

For high contrast, process in Kodak D-19 or Bluefire Micro.

Rescue old, yellowed photographs by copying them onto Bluefire Police through a blue filter, which blocks yellow light.

Kodak Technical Pan is no longer being manufactured.

Bluefire Police is an excellent replacement for Technical Pan. Note that, unlike Technical Pan,  Bluefire Police is panchromatic and does not have extended red sensitivity.

Bluefire Police is an excellent technical film for laboratory, police, and forensic documentation.

Bluefireℜ HR Developer Concentrate for pictorial photography

Use this developer to process Bluefire Police film exposed at EI 80, for pictorial photography. The resulting image has a full and rich gray scale and extremely high resolution. Images can be enlarged beyond the resolution limits of your lenses without loss of detail to grain.

Compatible with any stop bath and any ordinary photographic fixer. For complete instructions click here  (requires Adobe Acrobat reader). 

Also gives excellent results with most microfilms, and high-contrast 35mm document films.

This developer produces unacceptably low contrast when used to develop ordinary black and white films that have been conventionally exposed and processed.

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 discard.

Compatible with all ordinary stop baths and fixers.

About shelf 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 it is sealed away from contact with air. Properly sealed and refrigerated,  it can be stored for several months, perhaps as long as a year or two, depending on the quality of your tap water.

Mixing: Dry powder must be mixed in hot water, and can require prolonged stirring. Stir gently so air is not introduced into the mixture.

 

Bluefire 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.

Benefit
Feature
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).
High resolution 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.
Thin emulsion 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.
Clear base Shadow and highlight microstructure remain apparent at high degrees of enlargement. Clear light-dark transitions at the edge of microstructural elements enhances the subjective impression of clarity and sharpness.
Anti-halation dye undercoat The pink anti-halation layer stops light from reflecting back into the emulsion from the film base during exposure, which contributes to this film's remarkable sharpness. It is washed out  in processing, leaving a harmless pink color in your fixer. When completely fixed, the film base is completely clear.
Dual purpose 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. It is in regular use as a technical film, recording image elements as small as ten microns wide (a micron is 1/1000 of a millimeter).

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 photography.

Panchromatic Bluefire Police 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). 
Available with an optimized developer Bluefire HR liquid developer concentrate gives pictorial graduation and full film speed when paired with Bluefire Police. You can also process Bluefire Police in POTA, Formulary TD-3, Maco LP Supergrain, Kodak Technidol, and similar low-contrast developers.
