I shot them in RAW, that was after just a little bit of fiddling with Lightroom. The settings I used were ISO 100, F/9.0, 8 second exposure. I shot it using a Tokina F/2.8 28mm-70mm at 28mm mounted on my 600D with a tripod of course. The shot was actually pretty over exposed - thank goodness I had taken it in RAW. I had left the camera out unattended like I said and as the sun was coming up it brought a lot of extra light which almost made many shots unusable.
