According to Nikon the D600 uses the same Expeed 3 as used for the D4 and D800 series, with the same 12-channel sensor interface, featuring a very wide dynamic range which provides the possibility of lightening shadows or darkening overlit areas (high dynamic range imaging, HDR) with one shot when shooting in Raw image format.
