But then the shadows edges would look different.
Oh wait, that grainy look, you're right... Weird though, those shadows definitely were the dynamic ones being created by the lamp, i even remember that under Sam's hat was this non-shadowed part that looked weird so i had to get an angle that blocked that out of the shot, it's definitely a dynamic shadow
Maybe it was the map somehow? Or some kind of change to dynamic shadows? I'd try again, but i'm on the laptop which does not support dynamic shadows...
Edit: Wait, look again, open the image up and zoom into it and look by Sam's tie, you can see a slight graininess to it, i guess it was how close it was to the ragdoll that made it seem better or something
