I've got one SB-800 and was wondering if adding a second off-camera SB-800 would assist in group shots? My most immediate need is to take picutures of about 30 kids, as a group, in a church. The lighting in the church is probably going to be relatively dim. No bounce flash off the ceiling or walls would be possible due to the size of the venue.
I've looked over a Nikon publication "SB800 Techniques" and it does address off-camera flash techniques. Would these same techniques apply in a group shot? Would two flash units do the job?
Any suggestions would be most helpful. Group shots make me nervous.
