Yes, it will be adapting automatically. Also, it's calibrated for "typical" use cases, so very bright lights that are quite different from outdoor lighting would be the kind of thing that might confuse it. You can use the "set_controls" function to control these parameters. You could:
* Turn off the AEC/AGC ("picam2.set_controls({'AeEnable': False})") and AWB (set 'AwbEnable' to False). Maybe do this once they've settled?
* Or you could set specific values for the exposure and gain ('ExposureTime' and 'AnalogueGain'), and the colour gains ('ColourGains').
* You could restrict the AWB range ('AwbMode') so that bright lights won't tend to force it towards daylight.
