My dilemma then came to a head in Prerow on the Baltic coast, Germany’s most storied nudist beach.

After interviewing a few nude swimmers while still fully dressed myself, I spotted a large family — grandparents, parents and children — running into the water together. They were perfect. Three generations. Naked in the sea.

I really wanted that photograph.

But it felt creepy to shout at them from the shore, fully dressed: “Excuse me, um, can we take a picture of your naked children?”

There was only one way to do this.
