While on a shoot in portland I took these shots with a Canon 5D Mark III and a Phase One 645AF with a P25 digital back. I tried to make the images as close as possible and not edit them too much in post.
I thought they were pretty similar at first but once i compared the finals side by side the difference was huge. The Canon lost a lot of details in the light and dark places that the phase one kept and the phase one was much truer to the actual temperature/look of the room than the Mark III. Once again the phase one was the winner.
