Rollei Ortho Plus 25 ISO - 8x10/25 Sheets

Finally the Ortho 25 Plus is back in stock and comes with a new packaging!

Rollei Ortho 25 Plus is a technical, orthochromatic black and white photographic film with a nominal sensitivity of ISO 25/15 °. Rollei ORTHO 25 Plus is characterized by a high sensitivity reserve of up to two f-stops, depending upon development. The document emulsion offers exceptionally fine grain images with high sharpness. Rollei ORTHO 25 Plus is ideal for technical and scientific applications and as a half-tone film for pictorial photography  (e.g. street photography, landscape photography, portraits.

 The most suitable developers are low contrast developers, which bend the gradation so that, among other things, the tonal richness increases (more gray values)). The almost clear RC base opens up the possibility of using the film as a B&W slide film.

Technical and scientific applications: 

• Reproductions
• Reproduction of X-ray images
• Astrophotography
• Black and white slides and blue slides
• Graphic distancing (For this application in particular, we recommend Rollei High Contrast (RHC) developer (1 + 5, 3 - 5 min.).)
