Hello, is it possible to take JPG and RAW images with the Avata?
In the settings I could only find options for the (video) exposure etc.

Yes, swipe up, choose the camera icon and you switch between videos and photos. When in photos, settings will change accordingly. You can also long press the red dot button on both remotes.
You can shoot in jpeg, but not raw.
Actually shooting a photo freezes video feed for a second or so, this means photo shooting is best done while hovering.
