I have a client who has some personal footage of a park that she wants to use in a commercial. Question is, when is someone "featured" in a clip? Obviously, if you can't make out the face, or you've got a sailboat in the background, etc., it's a safe bet. But what about footage that is more medium/medium-long? A group of people standing in front of a fountain; someone walking by the camera -- stuff like that? If these shots were taken in a public place, where is the line drawn? Anybody know?
I've seen stock footage that was obviously staged, but others are taken on city streets, public bridges, etc. -- no way someone got permission from everyone on the street.
Any help or where to look would be appreciated.
Thanks
KH
