"DxO Labs has studied whether film really does have a better dynamic range than digital cameras. When based on measurements with a signal-to-noise ratio of 0 decibels, Kodak's Portra 160NC film (shown with the green line) has a wider range than the Nikon D3X camera (the green arrow-tipped line is longer than the black one). However, DxO argues that it's more practical to use a signal-to-noise ratio of 20dB, at which point the Nikon outdoes the film. (Nikon's newer D800 camera also outdoes the D3X in terms of dynamic range.)"

Yes, that was an interesting paper.  Here is its link .
