Video example of desaturated gameplay

After the Q & A for our game, the lectures mentioned that wouldn't mind seeing the game in a more black and white style and it made me think of the intro game play of Fatal Frame.

Game play should start 2:22 into the video.
The black and white part is only for the intro part of the game however, when you switch to play as the MC colours return to normal and I'm pretty sure only desaturates when ghosts show up (that part could happen in later games I'll have to check).
