    you could put some tracing paper where the film should be and the shutter on bulb and check for any difference between finder and film plane

  • That's some real ninja shit right there! Will give it a shot. Prob gonna run a roll through with a different lens to be sure. Got some shit old film and asda does dev only for £2 (useful for less precious rolls).
