The Astronauts is a Polish studio founded by some of the key talent from People Can Fly (Bulletstorm) and they're currently developing their first game - The Vanishing of Ethan Carter.
The game uses a technique called "photogrammetry" that basically sees you photograph environments and object from a ton of angles and then transfer them into the game. The official game blog has more on the subject. The end result can be seen in the screenshot below.
The Vanishing of Ethan Carter is set to arrive on PC this year.
