Time for the next question for the cosplayers! One thing that I've found to be tricky, is finding the best way to exchange contact info. When I'm taking hall shots at a Con, that can include trading info with literally a couple hundred people. The main thing for me is to get each model's info, so I can either tag them in a social media post, send them a copy of the picture, or both. I'm going to post comments with things I've done. "Like" the methods you like, and feel free to add your own!
