Have camera auto calibrate with specific analoguegain

[quitmeyer]

Hi everyone thanks to all your work our cool open source scientific tool for studying insect biodiversity has been working really great in the field!

There's one challenge I'm working on right now which is that I want to try to shorten my exposure times because sometimes our insects fly across the screen quite quickly and we get a big rolling shutter smear.

Currently, as you can see in our code:
https://github.com/Digital-Naturalism-Laboratories/Mothbox/blob/4957273d84673e9d69ca90a163188950dddd453f/Software/TakePhoto.py

We run an auto calibration every 6 minutes that sets the exposure time and the focus. This has been working well (with one caveat I'll explain below)***

But I wanted to boost the gain before I run the auto calibration in order to try to calibrate it for a shorter exposure time.

However when I try to do this, It doesn't seem to have any effect on the auto calibration. And so it just calibrates it with a normal type of exposure, And then when I apply that exposure to a photo with the analog gain, I just get a blown out overexposed photo.

*** Side question I had a strange problem where when I run the calibration. For some reason if If I run an auto calibration and then I take a photo using the settings that were collected on that auto calibration this photo comes out slightly brighter then if I use those exact same settings but do not perform an auto calibration before that. Anyone have any ideas about that? It's not really that significantly brighter so it's not that big of a deal, But it's irking me! :)
