Here's a copy and paste from another thread I posted in:
The next time you're at Barnes and Noble, take a look in the photography section at books by Sally Mann, David Hamilton and also by Jock Sturges. Sturges is more well known for it than Sally Mann or Hamilton, but all three put out books that have nude children in them. Sturges has two well known books called "Radiant Identities" and "The Last Day of Summer". Sally Mann has all sorts of family books. They're nudists after all.
You can even buy Sturges' books on Amazon: look here:

Sally Mann's books:

Just because a child is nude does NOT mean it's porn. Naturism / Nudism is a lifestyle. It is not pornography.
