6D Dynamic Range

Really? And I didn't know you had a light meter on the scene in the photo I posted. Or do all evenings adhere to some sort of sunset brightness standard that no one told me about?

Jeeze, if your 12 stop DR sensor can just about capture the full tonality of a scene, chances are.... it's a 12 stop scene. Although it should be noted that you've got a lot of blown out areas there. So would that shot have been better if taken with a higher DR sensor? You bet.
