Default: On camera / Auto
This setting only applies to the Time-Lapse mode. The default value of "On camera / Auto" will send simple shutter release commands to the camera. If you would like to choose arbitrary Bulb-based exposures, change this setting to "Arbitrary (Bulb mode)". Then you will be able to specify exposures from 1 second and up in hours, minutes in seconds. Please note that this setting requires a connected and enabled shutter cable.
