Hello fellow CSer, can anyone teach me how to use my SB800 as a slave unit? I tried to use my built in flash as a commander and when I trigger, the SB800 does not fire. Is there any step I miss out? Pls help. Thanks in advance.
You need to ensure that your commander is in the same channel as your remote flashes. Then you control them using the groups.
If you are using D70s as your body, the commander by default is channel 3 group A - which means you have to set your SB-800 to channel 3 group A. If you are using D80, D200, D300, you can use all 4 channels plus group A and B.
