I do know that you can ask the resort photographer to meet you somewhere on property and have a few pictures taken for no fee. We had a large group one year and wanted a picture taken of the group. The photographer met us by the pool one day and took a few pictures.
Otherwise, every evening there is a photographer milling about the resort who will take pictures for you. One year we were there during the holidays and ask the photographer to take some pictures of us by the Christmas tree. He gladly obliged without charging us a fee.
I think as long as you aren't having them follow you all over the resort for an hour that they will be happy to take a couple pictures for you. They even are out at sunset taking pictures on the beach.
Now, if you want to do a 'trash the dress' session, they will probably charge for that, but I don't know the cost. I would call the resort directly and ask to speak with the photo desk and ask them the question. 876.957.5960 This is the direct line to Couples Negril.
