Donald...if you PM me your email address, I can send you a Setup Guide for your camera. I can't send it through here, as it's in pdf format. Has to go through email.
I'm kind of thinking out loud here. Doesn't the exif data say that the exposure compensation is up 2/3rds of a stop? So the camera was already overexposing. Do you remember what you metered for (spot, center weight, entire frame)? That will effect how your camera exposes the shot.
