I am experimenting on using my sb800 as a remote flash with my onboard flash on my D200 triggering the remote. I have the sb800 mounted on a light stand shooting into a photek umbrella softbox that I've used many times with my studio lights. I figured that I would need more light than normal out of my flash. I set my camera on manual f5.6 1/125 and set the camera to fire the remote at +3 The camera fired the flash but after I took the shot the display on the flash said -3ev. What does that mean and why did it say that since I set the flash to fire at +3 on my camera? Also, what ev would you set using your sb800 in this type of shooting situation? Sure hope this all makes sense.
