From a hobby photographer’s perspective, I think it’s very important to respect other photographers’ work space, especially when many photographers are present for a small group photoshoot. If one photographer is already taking pictures of people, respect him/her as the primary photographer for that session and work around him/her. If you need better angle and need the photographer to move, ask when s/he is taking a break.
A little more respect for other people goes a long way. A very long way.
