The camera is a Nikon FE. I just finished a roll of film, and I'm trying to take it out by pressing the film rewind button at the base of the camera, then winding the film back before taking it out (which is the correct way to do it). However, the film rewind button won't go down even if pressed with force, so rewinding the film is impossible. Can anyone fix this? Thanks, and sorry I'm such a newb.
