I'm exploring the option of moving from continuous lighting to flash. I currently shoot with the Nikon D80 and have the SB600 although very soon I will be upgrading to the D300 and the SB800. I've been looking into alien bees lighting with the remote trigger. The little transmitter just fits conveniently into the hotshoe and all is done wireless. But, I don't want to lose my ability to use my SB on camera. Is there such a thing as a hotshoe splitter? Or does my SB600 have a way to transmit to the receiver on the lights? What about the SB800?
