I live in a National Forest, ( in the US) and frequently take photos of folks that do white water rafting in the area. Im considering now approaching these folks at their "take out" points on the river and offering them copies of the photos to purchase from me, since none of the rafting companies that do the tours seem to be doing this. Would I be violating any laws by selling group pics back to the group in the picutures, or by taking the pics without theirs or the rafting companies permission?
Thanks
