UPDATE: I received several mails from readers saying that this might be fake. I had second thoughts too when i first saw it but i believe, or at least i want to believe, that it's real and not just a good mask-work in post. It is of course a very doable & easy editing procedure that i'm doing often myself for several jobs but if you want to make it right it is also very time-consuming especially with shaken footage that needs to be edited frame-by-frame. So unless proven otherwise, i want to believe that this is real.
