Hi! I've got the new Arducam installed on my Mini, and I'm taking/uploading/downloading photos just fine. But I can't ever be happy with what I've got, so it is time to start tinkering some more. On the scan page, there are some additional controls next to the preview image. I've figured out what the MF switch does (Manual Focus, I think). Is there a guide somewhere to explain how to use the other controls? Preferably, one written for someone new to photography/photogrammetry?
