Not photoshoped, but a good visual effects video. Probably promotional viral video for some movie, in the style first person style of amateur filming like Blair Witch Project or Cloverfield ... I LOVE THESE KINDS OF MOVIES!!! :D
There is a weird date at the corner, 12-06-11, where the filming was made, with a line "This is the life". I searched for this, and I am not the only one to think like this: http://tvtropes.org/pmwiki/posts.php?discussion=13093231500A39040100&page=1 YAY! :D
