Tried to use a flash that was not attached to the camera. Part of the flash pad of the month. Always wanted to make the flash slave system work and this was a good chance to try it. found a good web site for a remote - slave system. http://www.nsteffen.com/archives/view/sb800-d300-built-in-commander/ So if you have a Nikon D-300, give it a try.
got this idea from Cindi from the Thursday's challenge.
