Rollei Infrared 400 Black and White Negative Film (4 x 5", 25 Sheets)

Rollei Infrared 400 is a unique infrared-sensitized panchromatic black and white negative film with a nominal sensitivity of ISO 400/27 without filtration. It is sensitive to IR wavelengths up to 820nm and can be used to produce unique halation effects with filtration and by varying the exposure length. It is suitable for working in both daylight and tungsten conditions and is characterized by a fine grain structure, notable sharpness, and high resolving power. Additionally, a good contrast profile offers clear separation between shadow and highlight regions. The film's polyester base has been tested to an LE-500 (life expectancy 500 years) archival rating and also features an anti-static coating. Additionally, this clear base is particularly well-suited to scanning applications.This item is one box of 25 sheets of 4 x 5" film.
