The shutter curtains on my Kalimar Reflex don't close completely after a photo is taken. Rick Oleson's web site for repairing Kalimar Reflex cameras shows some sketches for adjusting the shutter curtains. Is curtain #1 the lower curtain or the upper curtain? If the shutter curtain doesn't close completely should the shutter curtain adjustment be tightened or loosened? Or should I go poke a hole in the ice on the nearest lake and fish for rainbow trout and leave the camera adjustments alone?
