The second one is the real, take a look at the first one. It has basically the same color tone and lighting spread across the entire scape, the blurriness/photo imperfection looks, to me, like it was intentionally added. Also, lookat some of the little black rocks. They look sqaurish and fake.

Most importantly, Chruser isn't stupid enough to post them named real and fake, so that's a dead giveaway.

All this is just my own speculation, it could easily be another of his mind games.
