The Rollei RCN 640 is a color negative film. It is manufactured by Agfa Gevaert in Belgium as Aviphot Color N800 PE1 and assembled by Rollei as 35mm film. The Aviphot Color N800 PE1 is a film for aerial photography, especially high-speed aerial photography.
The sensitivity of ISO 800 is achieved only when it is developed for 4 minutes in the C-41 continuous motion machine. Normally, this development time is 3 minutes 17 seconds, reaching a sensitivity of ISO 640 only.
This film is only available as 35mm film in a twin pack (two films in one pack). Not much more is known about this film.
In the meantime, the production of this film has been discontinued. There is not really an alternative to the RCN 640.
