>>3158503Actually, while
>>3158516 is correct at many events, in a club you can often get away with flash due to the use of strobes anyway.
I'm relatively new to doing "proper" club photography, but know a lot of people will often use off-camera flash and will leave a flash in the booth somewhere and just shoot from all over the club. Some even leave a couple around the venue and get even more creative.
But a lot of the time, for wider club shots, it's counter-productive. You'll just light the DJ and booth too much and loose the atmosphere of the club.
