I really suck using multiple Nikon flashes and can never remember how to get the stupid flashes in the correct mode. I got a cheat sheet pamphlet from a Nikon rep at a CLS seminar and I finally remembered to pack it in my camera bag. I've been trying to find an online version for awhile of this cheat sheet and I've finally found it. Anybody wanting to setup their Nikon camera and flashes to try out the CLS may find this handy.

While on the subject of Nikon CLS, the Strobist Blog has linked to the Nikon CLS video which you can view on Google video. (View Strobist Blog Entry) This is the DVD that's now out of date since the SB900 release, but still valid for us mere mortals who only have SB600 or SB800 flashes.

Hope this info is helpful...
