"The analog gain cannot be directly controlled in picamerax, but various attributes can be used to “influence” it."

I think that's no longer true?

@rwb27 this is still true right? When we "set" the analog gain we're just putting a nice interface on these tricks, I think.

[rwb27]

No, when we set the analog gain we are actually setting the analog gain, with some caveats (like I'm not sure 1 actually means unity gain).
