no.10 Wide Spectrum Sheet Film

€45.00

The no.10 is a black and white negative panchromatic specialty film, yielding medium to high contrast, high resolution, high sharpness, fine grain and an extended spectral light sensitivity of up to 780nm. The emulsion has wide range of pull/push capability - from ISO25 to ISO1600.

This film was originally used for medium altitude aerial reconnaissance and cartographic or exploratory purposes.

TECHNICAL DATA

Physycal properties:

The silver halide emulsion type is coated on a transparent polyester PET base, with a base thickness of 0.10 mm.
The film provides excellent dimensional stability, great tear resistance; features an anti-scratch protection layer and has great anti-static properties. This improved emulsion has wide pull/push capabilities from ISO 25 to ISO 1600.

Processing:
The experimental no.10 film can be processed in various types of processing equipment including spiral tanks and automatic/deep tank processors. This film is highly robust and can handle less than ideal processing conditions and it will not contaminate the processing chemistry. This film must be loaded/handled in complete darkness due to wide spectral range sensitivity. If processed in a development tank manually, it is recommended to agitate the film for 5 seconds each 30 seconds of development. The development time must be decreased/increased by 15-17%. each stop of pull/push processing this film.
