This is what the guy said about the photo. Claims no funny business, but im by far no photographer....
The problem for him is two fold:-
a) he posted it to Reddit, rarely a welcoming place
b) "I took this photo 6 years ago today. It has NOT been manipulated. I will answer any questions about it.
" is a dumb topic heading considering it has
been manipulated and see a) above.
In terms of editing he's barely touched it though.
