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.
That sounds reasonable to me. We can certainly make the Arduino + camera combination compute and return statistics about the pixels (average, min, max, median, deviation) very quickly to find what are probably correct parameters without explicitly transferring each image. I wonder if there's something in the existing research about this, because phones and cameras certainly automatically compute exposure settings.
