@Lemonstein, I don't think that there is any vignetting going on in that shot. Judging by Ady's color corrected shot of the same scene, it looks more like the lighting for the set doesn't cover the entire area very well. The set was not really all that big, and you can tell they tried to hide the end of the set with alot of fog and darker lighting. You can also barely make out some fake trees on the far side. I cant tell if they are painted or if they are physical props.
