I have been reading up about light painting in this fashion for a couple weeks now and have found a lot of great tips but none of them ever specify what form of light they are using. There are a few that say "shop light" or "trouble light" but I fail to see how that works considering I tried with a 100w CFL in a reflector with all but stellar results. My friend in Orlando shoots cars for his business and/or magazine features. ( http://v2lab.com/theory/wp-content/uploads/2011/11/matt6.jpg ) I would hyperlink that but I have no idea how on this forum, sorry. I know he uses strobes at times, and has a set of AB800s in his studio. I've yet to ask him as he helps with a ton of other stuff I ask about so I don't want to keep asking. To me, the linked photo looks like strobes, simply because the light is so concentrated on the car and none of it really spills out into the gravel other than maybe 5-10 feet. The images I tried taking it was an obvious spotlight. This is also why I Think he doesn't use his AB800s. I know he uses 7-12 photos and edits them down to make one, but the part that tricks me is the concentration and the clean ??fall off? of light. Am I right in thinking he probably used strobes and the fall off is because of reflection rather than spill out?
