Legal or not, enforced or not, debatable or not, there’s still such a thing as courtesy. Would you feel comfortable if someone was making use of a camera on the nude beach you happened to be occupying? I certainly would not. I would not bring a camera simply out of respect for other beach goers. If my bare butt winds up online, I will be beyond upset. Correct me if I’m wrong, but I can’t think of any reason to take pictures there, other than lustful reasons. I would forget what is legal and what can be enforced, and instead consider basic courtesy.
