This is a cool hack for photography enthusiast and a DS lover, somewhat like me. This is one of the best mod I've seen so far. Since the DS was so portable, not to mention you can just pop out any game in between, why not make the DS more than playing games? Like setting up your Canon EOS 5D?
Steve thinks of nearly everything on when developing the mod for the DS, from taking bulb-mode to HDR interface. Amazing what some people can do.
