I hear the snark, but actually, that’s the correct way to do it.
I just took a photo of a stranger on the street about a week ago, because his t-shirt was pertinent to a conversation we were having here on the BBS. I approached him, told him I loved the t-shirt, and asked if I could take a photo of it to post to a discussion group. I assured him I would not include his face, and showed him the photo after I took it to confirm that he was not identifiable.
And that was regarding a full-grown adult.
