I don't know about that. Taking photos of young children in their home?? Then selling them??? Talk all you want about the fine line betwixt art and porn, but if there are children involved, I will always err on the side of caution and privacy. If they are out in a public place doing public things, I think you can argue the expectation of privacy, but in their home, even with the curtains open, it is much more questionable. When my kids were little, there were times when they would run around the house mostly or completely naked, say after a bath. I would hate for someone to have felt that they could photograph those scenes from 100yds away and sell the pictures with the full protection of the law. I think there is a reasonable expectation of privacy when we are in our homes, even if we are visible from outside.
