When does the timelapse interval start: when the 'shutter' is opened or when the 'shutter' closes? I was curious about low-light shots. If say I wanted 1s for motion blur and I had an interval of 2s, would the resulting interval be 2s (ie triggered on shutter open), or 3s (ie triggered on shutter closed 1s, plus 2s interval).
