I thought I had it figured out but I guess not... My question is: I got my SB-800 Speedlight last night. I'm trying to use it, mainly for off-camera lighting.. My problem is, to use it off camera you have to set it to REMOTE mode. You can change the distance setting while in this mode, but you cant change the power setting (ie: m 1/1, 1/128, etc..).. You can change it when you use it in regular mode, but it wont sync with the camera that way. You can change it in SU-4 mode as well, but for some reason in that mode it doesnt sync with the camera properly. The flash will fire, but the image is completely underexposed like you used no flash at all.. Very frustrating, and the book is very vague and doesnt provide much explanation.. Thanks in advance..
