If the shutter is part of a lens assembly some other mechanism is required to ensure that no light reaches the film between exposures.

If possible, the camera is set to a high shutter speed to reduce motion blur.

If the shutter was slow in closing, overexposure resulted where the part-fields joined and the " shutter bar " took the form of a white line.

If the shutter closed too soon, underexposure took place and the line was black.

If a shutter speed is too slow for hand holding, a camera support, usually a tripod, must be used.

If done fast enough you will be able to randomly " trap " the image between frames, or during shutter motion.

If the full-frame is transferred at one time, it is a global shutter.

If the camera is tethered with a triax cable, the analog generator locking signal is used to lock the camera control unit which in turn locks the camera head by means of information carried within a data channel transmitted along the cable.

If the circumstances are faced frankly it is not reasonable to expect this to be true.
