Bulb (pulse-width exposure) mode
Bulb mode allows the camera exposure to be controlled by the external trigger signal. The leading edge
of the trigger signal initiates the exposure, and the camera will continue to expose until the trailing edge
of the trigger, as shown. The readout sequence begins immediately after the trigger signal trailing edge,
and at the end of readout, the camera returns to the armed state, awaiting the next trigger. Any trigger
activity during the readout sequence is ignored.
