C-41 | The Rollei CROSSBIRD can be developed in the C-41 process. The C-41 process is a constant, uncomplicated developing process that is temperature-dependent. This means that it doesn't matter which ISO number you want to develop, the process is always the same.
E6 | Please note: If the Rollei CROSSBIRD is processed in E6 (as a color slide film), the film should be exposed at ISO 100/21°. The film then has a golden yellow appearance and gets the look of a warm summer day.
