It's not a competition is how I feel about other photographers at the same show, but that feeling is often not reciprocated. I am not going to write about pit etiquette because we have all heard about that. I am just always amazed at people who look at other photographers who aren't doing anything against the "rules" like they are evil. It is not a competition the best shots will be used and the end viewer decides the best shots.
To me it is all about capturing the music and the feeling. I have my style which tends to be very different than another persons style. Even a person I considered mentor had critiques of my shots that I didn't agree with. Is his opinion wrong, no it is his opinion.
No two people are going to get the same shot and there is room for all of us.
