Bulb Trigger
In Bulb Trigger mode, exposure time for each frame is determined by the trigger pulse
width. Exposure time entered into the software is ignored in this mode (see Figure 43). If
a trigger arrives during the readout of the previous frame, it is ignored. The shaded areas
denote the idle time between exposures.

Single Trigger
In this mode, the camera requires only one trigger to acquire a sequence of frames. Once
the initial trigger is received, the camera ignores any further triggers until the entire
exposure/readout sequence is completed (see Figure 44 and Figure 45, which show a
three-frame sequence).
