i've got a D90 and 2 SB600's. I'm looking at doing a car shoot that will require some lighting over a fair distance. I'm wondering what the exact limitations of the CLS are distance wise and line of sight wise. I have gotten away with some lighting before with the flash hidden so it hasn't be direct line of site, and i've never experimented with the distance of triggering. If anyone has anything they can pass along that would be great.
