Right, I've ordered my Canon 40D, and it will be in store a week on monday. I'm really interested in HDR photography, i just would like a few things clearing up. Right, my understanding is that you take several images of the same thing with different exposures. I've seen a few shots i would like to try out, and i will set the shot up with a tripod. I would like to know how i will change the exposure settings without any camera movement? I've tried shots before with a tripod and i know that even the slightest press of a button will make the camera move. I know some cameras can take different exposures automatically, but I'm not sure if the Canon 40D has this function. Does anyone experienced in taking HDR shots have any tips that could help an amateur? Regards, Jamie.
