http://images.wikia.com/starwars/images/a/ae/Battle_Hangar.jpg I really could do with finding out where this image came from. For example, is it a photo from a magazine, or what?
No, it's definitely not a screen grab; The lightsabers are only partially lit. I've seen many production photos, but this one is strange. The blend modes used are crazy. Obi's glow is really dull and unfinished, but it's definitely an official production photo, because the glows are too professional to be fan made.
