Nothing on them Photoshop wise Tim. That's almost exactly how they came out of the camera except a levels tweak to try and pick them up slightly but that won't affect the noise. It's just down to having a *very* expensive camera that is pretty much noise free up to about iso 2600. If you look at the start shot of the grid thats at iso 2000 and is still noise free.
Got to love the 1dMkIII. Much better than a Ninko
And thanks Gary. Andy's shots will look good in a photobook
