Thanks, so I guess in the picamera2 user guide, when it talks about a value, it is specifically talking about what would be passed into the Picamera2.set_controls() method, while for reading the controls (with Picamera2.camera_controls) I should expect the three-element tuples of (min, current, max)?The tuple you are looking at gives (min, max, default) values for the controls. So, for your AnalogueGain example, the minimum value is 1.0, max i s 63.9. I'm not sure why the default is set to None, that may need to be looked at further.Some examples:
* AnalogueGain is documented to be a single floating point value, but when I output it, I see a three element tuple. For example: (1.0, 63.9375, None),
* FrameDurationLimits is documented as being a two element tuple, but the output is a three element tuple.
For this first generation camera module, this is the list of controls and their outputs:
Code:
