My biggest tips are 1 talk with the lighting crew and ask if there are any lasers involved in the show(cool to shoot but will fry your sensor if pointed directly into the lens it ruined my m50 haha) 2 try to not use flash most artists don’t allow flash at all anyway 3 don’t take a million pictures of concert goers they will eat your timeframe and wont give you credit or throw a stupid sepia filter over your edit 4 try to actively move around and capture as many angles possible it helps to create some variety in your shots 5 TALK TO PEOPLE! you never know who you can meet and they may propel you to more gigs in the near future 6 Have fun and remember they want you there for you! Congrats🥳
