 ROLLEI PAN25
ROLLEI PAN 25 is a panchromatic sensitised black & white film with low speed ISO 25/15°. Besides the excellent fine-grain this film has a very good resolving power and a high edge sharpness. ROLLEI PAN 25 is characterised by a high sensitivity reserve of one f-stop, depending upon development. The thin-section document-emulsion is poured onto a highly transparent base and offers extraordinary sharpness and the finest grain. ROLLEI PAN 25 achieves the highest image quality with very large scales of magnification.
Characteristics and application:
- panchromatic sensitised with low speed ISO 25/15
- special coating for an improvement of the transport properties of the cameras
- suitable for daylight and tungsten
- polyester base support guarantees the highest level of archive stability (LE 500)
- spectral sensitization 400 - 650nm
- very fine grain and high sharpness as a base for negatives with an excellent quality
- with "non-curling" backside coating to improve flatness
- glass clear PET base, especially suited for digital scanning

Storage:
It is recommend not to leave the film material exposed in direct sunlight, strong heat or relative high humidity.
Cooled stored film material should not be used until film is warmed up to ambient temperature.
– Unexposed film: Up to 24 months in cold storage by 8° C is recommend
– Exposed film: After exposure, please keep film in cold condition, processing as soon as possible is recommend
Processing:
Rollei Pan25 can be treated like any other b/w film and can be developed sucessfully in all standard developers. To maximize the tonal range a developer such as Rollei RLS (LP-Supergrain), Microdol-X or Perceptol is ideal. For recommended development times, please consult The Massive Dev Chart. To achieve optimal results, a test development is recommended.
