Multiple threads on here that have more detailed information, just scroll down and/or go back a page or two. Bottom line, if your aren't an idiot, you will be fine. (asking the question on here, probably shows you are respectful, so I wouldn't worry. How else would we all have pictures in albums)
Taking pics in the morning in the beach is a regular activity that we do every trip. Early morning light is great and the beach is almost empty. You can if you are decreet that whatever kind of pics that you want including nudes. The early the better and you will not run into an issue just some smiles from anyone else out that early.
We take our pics, with respect for folks who may not want their pics taken. Simple. Of course, late at night at Patyo's after a few rounds of Wet Pussies, who does NOT want their pic taken? Really...
