D40 run by computer?
I have a Nikon friend who was asking if his D40 could be hooked up to a computer and actually run via computer actions, rather than via the camera's mechanics? If so, is there some software that he should know about? And finally, is there any FREE software for this? Other than this, I have no idea what he's talking about, but can get more information if it might be required to help in answering his concerns.
