srsly, two clicks from the same spot will do for the mechanics of the picture taking. The camera's "trick" would have to be to let you explicitly control the exposure. Expose the first picture so the lightest part of the frame is properly exposed, leaving the dark part really dark and then another snap from the same spot with the lightest part properly exposed and the bright parts blown out. Then ... overlay them... ok.. that's where the software comes in handy, but the idea's the same.

Now *I* want to try it... I'll be keeping my eyes open for a likely subject.
