It's impossible to please everybody all of the time but there are some guidelines that I like to think are applicable to the pit. Keep in mind that you're in the no man's land of the performance - a space that traverses the gap between the artist and their fans.
TRIPODS: No. Pits are small and we’re only in there for a short time. Photographers need to run around and sometimes the artists will hop into the pit too so stay mobile.
YOU: Nobody is there to see you so it’s polite to be discreet and allow the patrons to enjoy the show without distraction. Out of respect (especially if I'm granted stage access), I will always wear black.
CAMPING/CHIMPING: The pit can be small, grab your shot and then move over to allow someone else in. It can be convenient to find an awesome spot and stay there but try not camp out/hog the spot.
BEEPS: Turn off your the beeps. There’s nothing worse than hearing a camera beep every few seconds when the artist is in the middle of a really intimate moment. There are other less-invasive indicators that will alert you when the camera is in focus (other than your own eyes). The same rule applies to the AF illumination assist beams.
DRINKS: Really now. Save it for the fourth song.
SPECTATORS: Sometimes you will catch a sneaky PR-intern or an, “I’m with the band”, person in the pit. They’ll likely be in there with their phone, taking selfies and generally having a great time. If they’re a nuisance or in the way, politely mention it to them or take your concern to security.
STICK UP: If your camera is in the air more than it is pressed to your face then move back. Don't stick your camera in the air in front of the singer so it ruins everyone else's chance of a good shot. If you need to get closer then buy a longer lens.
BACKPACKS: You'd think this is all pretty obvious but I've seen my fair share of photographers with their giant backpacks in the pit looking like they’re on their way for their first day of school. Also, don’t leave your lenses on stage as they get in the way of everyone else having a clean wide shot - there will only be your tears when it plummets off stage.
LOOK AROUND: A quick glance over your shoulder will stop a domino effect of four shooting photographers falling to the floor. Photographers not showing consideration for other people’s location is the biggest cause of pit shiners.
ETIQUETTE: The majority of photographers are in this business because they love live music so it’s really important that you enjoy the show. I’m not talking about moshing away in the pit (you’ll soon see where that gets you) but be polite, talk to the other photographers - they're not competition as much as they are brethren.
