I'm at a volleyball tournament and there is a large company who has a booth set up and is selling pictures of the girls play. Parents have the ability to request that they come and shoot pictures of their games. I'm the parent of one of the volleyball players but I also sell sports photography pictures. One of the staff photographers came to a match that I was taking pictures of. I was taking pictures of both teams with the intent of passing my card to parents of the other team to enable them to purchase from me in addition to (or instead of) the company sponsoring the volleyball tournament. A representative from the photography company went to the other parents on the team and asked if I was with them. They said yes, of course.
With this background, am I legally allowed to shoot pictures of teams other than my own and sell pictures to their parents? I don't want to break any laws, but I'd also like to make a few bucks while I'm at this three day tournament.
On a side note, I went to the photo company booth and asked to talk with the mananger. They said he was out taking pictures. I left my name and number, but he hasn't called me back.
Any help on this would be appreciated.
