ABSTRACT:
The motion picture camera which is adjustable for taking individual pictures has a rotary shutter and means for locking this shutter in an open rest position thereof. This open rest position, at which the shutter passes the exposure light beam, is effected immediately upon the completion of the film advancement phase during one turn of the rotary shutter and can last for an arbitrarily long time period. This long time exposure is terminated by unlocking the rotary shutter simultaneously with the actuation of the release of the camera for taking the subsequent picture.
