Unjamming a Canon AE-1 with mirror up and curtains open

A jammed Canon AE-1 showing two visible symptoms: mirror raised and shutter curtains left open.

A mirror up with curtains open means the camera has stopped in the middle of its cycle. Forcing parts back into place can make the damage worse.The first step is to understand where the sequence has locked, then release the mechanism in the correct direction.Once the camera cycles again, shutter timing and mirror return still need to be checked.
