Maco ORT 25c (36exp)

The Maco ORT 25c is a black and white film. It was offered by the German Hans O. Mahn & Co. KG. In the meantime, it is no longer in the photo retailer’s range.

The ORT25 uses a thin-layered document emulsion with traditional cubic crystal technology and orthochromatic sensitization.

The ISO values/film speed are not standardized due to the lack of industry standards for orthochromatically sensitized document films. However, it is recommended to start with an exposure setting of ISO 25/15° (based on a light measurement with the meter pointing from the subject to the camera).

The ORT25 is particularly suitable for reproducing documents and X-ray images to create black and white and blue slides. Its high sharpness and resolution also make it suitable for general graphic purposes, special effects, and photographic halftone applications. Its characteristics make it ideal for archival purposes.
