When moving about in a club.

Moving around taking pictures in a night/dance club has its own challenges.   Its often dark, and you need a good dependable flash.  But even more difficult is that you don't always have the flexibility to get "the right angle" while taking the shot.  You may find yourself just a few feet from your subject and no room to move back.  For these reasons I like to have a good zoom lens short enough to allow me to get as much of the person(s) in the photograph as possible.  A good strong flash aimed at the ceiling with a reflector attached to fill in from the front will soften the light and help to minimize harsh light and shadows from your photograph.
