Project 1: Second Upload. More Film Grain, More contrast. Less reds. Less brightness on teh smoke rings and clouds, more for subtle effect than fx impressiveness. The vignette has been keyframed to move slightly to add more to realism and less robotic cameramovement. .
More true to the original test videos of small atomic bombs of the 1940s and 50s (the larger atomic bomb tests had those big clouds seen more in the first video).
