Camera Problem

If you look at the EXIF info. you will see that the camera is overexposing like crazy. This should have been more like f/11 @ 250sec.
Even with these settings of 1/1600sec @ f/18 with exposure compensation of four stops, I had to darken the image significantly in Lightroom.
We tested the camera at a camera store belonging to a friend of mine, and came to the conclusion that there is something wrong with the camera.
I have contacted Nikon USA and am waiting to hear back. I will let you know how it goes. Luckily I have several back up cameras.

The image was taken at the corner of Park Blvd. and Monroe St. A new mural that will probably not last long.
