Two times nix

The film is a cutout for the camera, and accurately so that there were problems with the second film.
This stuck halfway across the camera what the use then made impossible. It makes sense to the label for releasing the first support sheet is attached opposite of the recess and it is more or less forced also to begin to apply there the film. Solving the carrier foil completely you risk getting fingerprints on the protective film.
Bring not exactly the film to it comes to the problem with the camera, as do dramatically apparent in the size of minimal deviations at the end.
