Here's an example - Say Cindy Citizen Journalist is filming herself on the steps of city hall to get the news out about the horrible new by-law making it illegal to park your car with the windows down! The frame isn't zoomed into only her nose, but rather a more reasonable full body shot with the sinister den of iniquity (city hall) behind her. People are still going about their business and most people walk behind her, but are clearly visible in the frame. Shy Stan walks behind her and is also captured in the video.
QUESTIONS:
- What is Cindy filming?
- Is Stan "being filmed"?
The first is obvious - Cindy is filming herself in front of city hall.
The second has 2 answers - yes and no. Those 2 answers have very different presuppositions regarding "filming".
Yes assumes that anything in the frame is "being filmed".
No assumes that the intent and main focus of the frame is what is "being filmed".
But, that's just one example of a focused recording, and doesn't include the "Google Glass" scenario.
For general surveillance cameras, it seems that we would usually say that whatever is in the frame is being filmed, similar to the "Yes" answer above. i.e. Shy Stan walks past a surveillance camera, so, he *IS* being filmed.
Does the same apply to Google Glass?
If not, would we then say that someone is being filmed (by GG) if they are framed and in focus, but not being filmed if their appearance in a frame is incidental? Where does the line start to blur?
This site has a lot to say on the topic:
