I have a Nikon FE2 35mm. The lever to advance the film is stuck! I want to take off the base plate to see what is going on and to try to fix it, but I have a roll of film in the camera. Would removing the base plate expose the film to light?
Whatever is causing the film-advance lever to be stuck involves a chain of components that are in contact with the film. Even if removing the base plate does not itself expose the film to light, exposing the stuck components would likely allow light into the camera.
If there are any shots on the film that you wish to preserve, you should remove the film before attempting to operate on the camera. Although the film-advance lever is stuck, you may still be able to rewind the film. Otherwise, you will need to use a dark room or changing bag.
