If you’re doing a “to-camera” piece in public, then the credibility that you’re automatically afforded by those who pass you in the street is directly related to the number of crew you have with you.
Watching a guy recording himself on a handicam at Kings Cross, I noticed that he was being bumped and jostled by any number of passers by who could see what he was doing, but didn’t care about interrupting him because his lack of crew indicated that it probably wasn’t very important. Crew of zero means you’re probably blogging on the long tail with a viewing audience of zero.
As you start to amass crew, the repect & space afforded to you by the general public will increase according the number of crew that you have. People see crew, realise that what you’re filming is probably legit and will give you more space.
This increase in respect will plateau at about 4 and will then actual diminish if the crew approaches 30. This is due to the fact that as the crew increases, it becomes statistically more likely that Nicolas Cage is involved with the project, a fact that will not only decrease cred, repect and space that the public is willing to give you, but may also result in the crowd becoming angry and violent, especially if they’ve seen Ghostrider, Next or Knowing.
Colloquially, this is known as Cage’s Reduction.
