This mode is a combination of Timelapse and Lightning modes. You can take lightning photos while timelapse is in progress without disturbing your time-lapse sequence. This mode has 4 parameters:
Sensitivity: This value determines the sensitivity level of your device for lightning. The higher the value you set, the more sensitive it will be. You can move the threshold bar by holding and moving circle with arrows or use "+" and "-" buttons.
Interval: This parameter defines the duration between the starting points of each frame exposures. Please note that Interval value must be longer than exposure value.
Frame:This parameter defines how many photos will be taken. You can set the frame number up to 65543. If you set the frame number to 0, this will mean that the time-lapse will continue until you stop it.
Exposure: This value defines the exposure value for each photo. You can select the exposure value from exposure list or set a custom exposure (if your camera is in Bulb mode and your camera support Long Exposure function).
You can see the light level of environment without starting the mode so you can adjust the sensitivity threshold according to light level bars. When a light event detected which exceeding the threshold value, it will be shown as "Orange" bar in this screen.
