Thanks guys for the comments and votes.. every single element on this photo is real. I PP it that don't look real to fool but some really good to judge the photo..
This definitely looks real, although I suppose you could have combined shots. From the standpoint of evaluating the image, I find the red cast on the foreground troublesome. Also there is a white area around the lower part of the fisherman, which might indicate that he was added to the scene and/or the color of the sky was manipulated. So I'm going to say NOT REAL.
The first time I saw this I was convinced it was a composite, but now I can't see what I might have noticed to lead me to that conclusion. Interesting photograph and for my final answer, I will say: real.
