This is an overexposed JPEG - 1/320 at f8 would be right for bright sun, yet if you study the data, the exposure claims to be have been set at -1 override. It's probably the worst exposure of 71 frames taken. However, the image can be recovered fully from the raw .ARW file using Elements 4 or PS CS2 with Adobe Camera Raw 3.4 (beta implementation of raw conversion is included for the Alpha). You can download the raw file from: http://www.f2photo.co.uk.nyud.net:8090/_DSC2832.ARW.zip

Dynamic Range optimisation was not turned on for this image as far as I know, but was turned on for the next one (wider view of the oven area).

Please remember these image are copyright but I am releasing for anyone to experiment personally.
