Very fine-grained, high resolution film with sharp edges for highest detail reproduction and extreme enlargements. The Rollei ORTHO 25 plus is ideal for a wide range of demanding applications.
The Rollei ORTHO 25 plus is orthochromatically sensitized with a nominal sensitivity of ISO 25/15°. It is a technical, steeply working black-and-white film with a high sensitivity reserve of up to two apertures (depending on development). The document emulsion offers an extraordinary sharpness, with finest grain and extremely high resolving power. The ORTHO 25 plus is used for technical-scientific applications and as a halftone film in image-based photography. But also charismatic portraits, high-contrast still lifes and epic landscapes are no problem for him.
