I talk, of course, of the practice of having a TV reporter walking down a busy high street talking to a camera a half a mile away with a special lense, it makes me cringe when the pedestrians inevitably give him he's a flippin' looney! looks
One of the worst examples I recall was the occasion where a Beeb reporter was walking down Oxford Street doing a trail for a prog' on STD's Ghonnorea...VD...Herpes...Thrush...AIDS he earnestly enunciated in front of the stupified shoppers covering their children's ears
I had to do something similar as a student. We took turns in being director/camera operator; reporter; and sound engineer.
When we shot close up people would wave or avoid the camera, ruining the shot. Shooting from across the street obviously meant reporting in between the passing traffic, but the results were better in the end.
You must be talking about the camera being nowhere in sight though. I bet it's embarrassing for those reporters; still, everyone's gotta start somewhere - they could have their own tea-time chat show one day!
