A film director may spend days working with cameramen to plan a complex scene with lots of actors. This is necessary to capture dramatic interactions without also getting bits of equipment in-shot.
Today’s invention is instead to equip each actor with a small, covert camera, which runs throughout a scene. This would involve a tiny lens probably best be positioned above an actor’s ear and, if necessary, coloured green to enable it to be automatically painted out later.
This would allow the actors to move much more freely and generate point-of-view footage from several perspectives. The views could later be intercut into a final version (or perhaps multiple different versions).
Each actor’s camera could automatically process their view using aspects of their character (such as sepia, for an older person, enhanced shake for someone who was cold, defocussed for a person with a visual impairment etc.)
