Note: experiment with exposure settings to figure out how to get decent pictures in outdoor light.Yes, definitely necessary. I wonder if we could come up with an automated tuning algorithm that would, instead of sending a full picture, just send the average pixel intensity. Then, iterate over the settings, fetching the average intensity each time, until it reaches ~50%.
We almost certainly want to optimize spread too. A standard deviation < threshold value meaning we are only getting CCD noise.
