When I first saw this question and its answers, one of the answers was apparently from the actual photographer, and he had described details of how he took the photo, how he digitally enhanced it and finally made the version in the question. At the time, that answer had even more up-votes than the accepted one.
However, now it seems the answer is gone. Why was it deleted? It seemed to be a good answer and a good addition to the site. Was it deleted by a moderator or by the owner? Is there anyway to get it back?
