So I did some further testing of these radio triggers and find something baffling. I can hold the SB800 with my left hand and the camera with the right hand, and shoot with the flash held out to my left at arms length while pointing at the subject, and I'm shooting in TTL on the units, A mode on the D800. I've got the SB800 at -1 1/3 just to reduce the light a bit. But when I take a series of photos without even moving the flash or changing anything, the first image is dark as if no flash went off, then the second one is fine, good exposure, then the third image is way to bright and the flash almost seems like it goes off full power. I can repeat this strange behavior every time I change a setting on the camera or just move to another subject. The flash itself is set to TTL and shows all the correct settings on the camera, so the communication is fine. And if I angle the flash away from the subject, oftentimes the images look as if there is no flash. Yet if the flash is on camera without the triggers, there's plenty of light and correct exposure. Flash settings in the menu of the camera are all on TTL. I fail to see what is causing this inconsistency in the exposures for sequential and otherwise identically set up images. I'm shooting at 1/250th second (AP) sync setting in the menu, but when the triggers are on, the camera shows 1/60th of a second on the LCD readout on the top. Really strange.
Might be time for pocket wizards.
