Sun creates silhouette.
Since the camera’s only goal is to even out the light in any scene, pointing it at the sun will cause a massive under-exposure for the subject. If that’s your intent, it will work every time. Add interest to the shot by dialing in a rather small aperture. You camera control people will want to know that this shot was taken at: ISO 200, f16 @ 1,000, e/v +.3, 52mm lens, Center waited metering.
