This whole photoshoot was inspired from this tumblr.
I have not really looked at it, so I hope the edit of the pictures are okay. Robin knows more about this than me, so I’m mostly just guessing.
The light and colours and stuff didn’t look like this of course. If you remember this, then that is the original lighting.
But it is dark and all, and you can’t really see Deans demons eyes, so it might be considered Purgatory as well? Maybe?
