First, thanks for the reply.
Yes, a release form would work for the future work I do, but the clips I'm posting on my site is from things I shot before I had a business, so there are no forms.
Funny you should mention nudist wedding, because that is excactly why the attention was brought to me. On my site, on the "demo clips" page, there are 4 clips. There are two of them... that one of these two is a 9 minute clip of a family occation that in it, my brother is seen for about 3 seconds. Another clip is a 4 minute clip from a New Years party that has censored nudity in it. On the bottom of the clip I have written: "This clip contains censored nudity (stripper). Please be advised."
A family member called me and said that the nudity is censored ok, so there's no problem with that, but since my brother is very religious, if he knew that he was seen in a clip on a website, on the same page that has a clip with censored nudity, he might be upset.
Now, I know for a fact, that my brother, being religious and all, will never surf the net, and never know about this. Besides, he is not a main subject in the clip... I just don't see any reason that I should take into consideration someone being shown in a clip on the same page as something else shown in a different clip... It's not like I put censored nudity in the same clip as him!
So where are the limits?
