It is a unique black and white film in several respects. With a nominal sensitivity of ISO 400/27°, it belongs to the category of high-sensitivity films, yet it offers an extraordinary fine grain that is typically expected only from a black and white film of a lower sensitivity class. This exceptional performance results from the use of modern color film technology. It is a so-called chromogenic film, whose blackening in the negative is caused by the dyes formed during development rather than, as is common with conventional black and white films, by metallic silver. This not only means that it is an outstanding product but also offers the advantage of being easily processed in any color lab or minilab using the standard C-41 color negative process, even alongside color films. The negatives can be enlarged or copied onto black and white photographic paper just like conventional negatives.
