It's been years since an independent manufacturer created a new black and white film. The BluefireT family of products is made up of a new combination of 35mm high-resolution panchromatic film and matching developers. Click here to see where you can buy these products. The Bluefire Police film-developer combination is designed for making photographs that will undergo extreme enlargement, or will be scanned at multi-megapixel resolution. The film is an excellent microfilm or technical film when processed in high-contrast developers. At the same time, it offers a long, beautiful tonal range and a useful speed when processed with an appropriate low-contrast developer (see examples).
It has a single thin, hard, monodisperse, ultra-fine grained light-sensitive layer and an anti-halation undercoat which gives it extremely high resolving power. The sensitive layer is coated on a film base of normal thickness, so it handles normally in the darkroom and in the scanner. The anti-halation undercoat washes out during processing, leaving a completely clear film base. Bluefire Police film is panchromatic, sensitive to the entire visible spectrum. Like all panchromatic films, it must be processed in total darkness. Most fine-grain films and technical films must be exposed at ISO 25, or even at ISO 12. Bluefire Police can be exposed at the very useful speed of EI 80 for pictorial photography, and EI 100 for technical or microfilm use. (There is no ISO standard for establishing film speed with films of this type, so all Bluefire Police speed values are quoted as Exposure Index values). | ||||||
