HDR processed through Photomatix 4.2 using the Raw files, 7 bracketed shots from -4 to +4. I didn't do any tweaking in Photomatix, just took one of the presets ("Photography" if I remember right). Shot with a 24-70, 24mm ISO 100. I also took the same shot with the in-camera HDR mode which produced a shot that was significantly greener. I'm usually pretty happy with how the 5D3 HDR mode performs, in this case Photomatix gave me a more realistic shot.
