What camera do you think is best for shooting HDR images? Would it be the Hasselblad HD4-60? How about the Canon EOS 5D Mark II? Many people may prefer Nikon and the Nikon D3x might be the best for any of a number of reasons. For example, the D3x can do nine bracketed exposures! I am convinced that any of these fine cameras would be an excellent choice.
However, in my opinion, the best camera for shooting HDR images is the camera you already have! That is, as long as it’s a fairly decent digital camera. Eventually, you may want to upgrade to a better camera, but I suggest that shooting quality HDR images has more to do with your general photographic skills and your technique as opposed to using any specific camera.
