The AJC international auto show in Atlanta? If so, then I suggest you adjust white balance to the overhead warehous-like lighting FIRST when you walk in the door. then take pics without flash (harsh on chrome and windows and such) and try and get a variety of pics. closeups, far aways, full car shots, artistic shots like headlights or taillights, interrior, eye-level with headlights makes agood 3/4s view.
Ya thanks for your response, I'm fully aware of white balance, mode, everything, I was actually thinking about that if I should take pictures with flash or without flash...
