Any club photographer here that want to share some tips?

curious about club photographers experiences and techniques

used to be one! don't know how much experience you have so i'm just gonna share all tips that come to mind:
wide angle lens (prime 20mm or 24mm, zoom 14-24mm)
open aperture bc low light
invest in a fast flash
slow shutter with flash to get these cool motion light effects
just go up to people and wether ask the to take a photo or just catch them in the moment
when editing always make sure your skintones are correct (green undertone makes a person look ill)
