When this family took the film to be developed at the local photo store ( yes this story is that old ), the store employees did not panic and call the police. The family was very open about their nudist life and friend who worked at the photo lab that knew they were nudists was able to see the photos in the light we all would want, as no big deal - or just cute family photos.
It was a great story of how being open about nudism in your life can be a good thing. If you hide your way of life, that implies there must be something shameful about it, and people can take that queue from you. In my humble opinion, its better to be open about who you are.
