Image exposure bounds


Product: [Bebop/Bebop2]
SDK version: online documentation

According to the documentation I can see that the default bounds for image exposure are [-3:3].

I would like to calibrate the drone camera for my experiments. In order to do so I need to know:

  1. what are the units used here? If I set the image exposure to i.e. -1.5 what does it mean for the exposure time of the camera?
  2. How can I change the default bounds?
