Black and white, orthochromatic film.
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.

Orthochromatic black and white film with fine grain and sharpness - ideal for landscape photography.
Film can be processed/exposed to red light in a photo booth.
ROLLEI ORTHO 25 Plus is a black and white film with an official nominal sensitivity of ISO 25/15°. The film is sensitized ortho-panchromatically ("red-blind"). This means that red is represented as black.
If you develop the film in a Rollei RHC developer, you get a steep gradation - high contrast.
Please note: The Rollei Ortho 25 Plus has a very different emulsion compared to its predecessor. Therefore, you need to adjust the exposure and development accordingly.
