- Number 1 and a full circle show that the film is still unexposed
- Number 2 and a half circle show that the film is partly exposed
- Number 3 and a cross sign show that the film is fully exposed but not yet processed
- Number 4 and a rectangle show that the film has been processed
So if you can see a cross sign or half circle, take the cartridge to a photo lab to get it developed. Or if you see a rectangle, there are still negatives inside, in which case you can keep hold of it or take to a lab to have the photos printed.
