There's No Place Like Home
In a family with permissive attitudes toward nudity, claiming they're practicing "home nudism" is a stretch in some imaginations, but tell me, how exactly should it look to you? It's just people being naked, in this case within social atmosphere of the family.
Call it what you will, regardless of label it can be interesting to witness (See: Family Nudist Photo Album). Many Europeans haven't bothered to give a name to how they behave at home, but in the eyes of the average American family, it decidedly "nudistic." The fact of the matter is they're simply not as hung-up with their bodies or body image. It is what it is. Brother is different from sister, mom from dad. No big deal.
But it is worth a thorough, photo-journalistic treatment, hence "Nudist House" (and "Candid Nudity"). Simple nudity enjoyed by real people sharing the planet with us.
