David Burnett is a pro who has made a solid reputation over a long career. Interesting that he would confess this lapse. He wasn't ready and I think that is the point he is making, he took it as a lesson learned and got better as a result. The article seems to have an odd pro-digi bias, as if changing a memory card, no matter how "blazingly fast" wouldn't also cause one to miss a shot. Silly.
