Hi, I have a Nikon D80 camera and a Speedlight SB-800 flash unit. I want to shoot using the remote flash option. I was able to set that up but I can-t seem to find a way to disable the on-camera flash so that I have only the remote SB-800 firing. So far it will only fire if the camera flash also fires, and that messes up my shots. Does anybody know of a way to do that?
