The Rollei Ortho 25 is a technical, steep black and white film with a nominal speed of ISO 25/15°. The Rollei ORTHO 25 is characterised by a high sensitivity reserve of up to two f-stops, depending on the development. The document emulsion offers exceptional sharpness, with the finest grain. The Rollei ORTHO 25 is very suitable for technical and scientific applications and as half-tone film in pictorial photography. The crystal-clear PE base material opens up the possibility of using it as black-and-white slide film.
