I wonder whether I wound the film too tight when i put it in the camera in the first place. I say this as at the end of the film after 36 or 37 shots, the film itself was loose and i wondered whether it had come away from the film canister. Because of this I took it out of the camera in the black bag but then discovered that it had not come away from the film canister.
With regard to developing. I did nothing different there that I can think of and the film development container appeared secure.
It is very strange.
Your negatives, then, are grossly underexposed. That could be caused either by a shutter that isn't opening, or sticky aperture blades that are stuck on f/16 or f/22 even though the aperture ring may turn.
Check your shutter speeds one at a time by shining a flashlight into the film chamber and then activating the shutter. You should see an natural progression from slow speeds to fast, and you should see light through the shutter curtains at every speed.
Also check your lens, off the body, by rotating the aperture ring fully from wide open to fully closed and back, one stop at a time, and seeing if the blades open to the corresponding position of the ring.
It may be that some piece of gunk was causing havoc and it's fallen out... or perhaps "things" just needed exercise to distribute the lube properly or who knows? The best cameras are those that fix themselves.
If your problem persists, though, keep that roll of film and send it with the camera back to your camera repair person so he can figure out what happened.
