I'm using the Arducam 5 Megapixel camera (meant for Raspberry Pi) because it has the capability for changing the lenses, and using the
picamera module to run it (in Python 3). I'm taking pictures that need to have very consistent lighting, but all the pictures have a bright white spot in the corner, even when the camera is entirely covered, so this is clearly either a problem with the camera, or some sort of auto-contrast or auto-lighting adjust that
picamera does. Is there some way to to turn this sort of thing off with the
picamera module to see which it is?
