That certainly is a picture to put your blinkies on the red channel! Got to wonder what your default settings are when coming into CNX if it shows OE. My first experience with RawDigger shows no over exposure. Photoshop seems to think the file above has a blown red channel when in Adobe98 color space, but not SRGB or ProPhoto.
