During a couple of recent broadcasts, notably "Peter Pan" on NBC, I've noticed some pretty vivid fluorescing from the teeth of the talent. It was most vivid on the actor who played Peter Pan and was even mentioned by a couple of the TV critics. I've also seen the whites of eyes doing it as well.
Do we know what causes this to happen? Is it an effect that is being used incorrectly? Is it something to do with the latest generation of camera sensors? Is it lighting related? Is it a chemical thing—something in the teeth whiteners or tooth veneers that is causing this? Is it only with broadcast-style cameras?
And, of course, Is there a way to avoid it?
