Photes are very over exposed, Fiji f700 - Cameras

Check your exposure compensation adjustment. If that is set high, then all your shots will be over-exposed until it is brought down to the "0" setting. A relative had this problem with a different camera, and all it took was resetting the exposure compensation to make things work correctly.

I often set cameras with a default exposure compensation of -0.3 EV since blown highlights are so distracting.
