I went to Donington to enjoy the heavy metal festivities and noticed something that seemed to happen every time someone spotted themselves on the big screen as the camera swooped around the audience.
I kept seeing the side view of them as they waved/gurned/stuck their middle finger up. None of them were shown facing forwards. None of them twigged all weekend.
WAVE AT THE CAMERA, NOT AT THE SCREEN YOU GAWPING TWATS.
