This is Biffy Clyro performing live at Wembley. Many cameras do a great job of always being targeted at something interesting, allowing the best shot to be used at any time. Fast shot changes keep us watching.Angles and shots all clearly show this is a life event with an audience.Live coverage of music almost never has a distinct visual style over others, its very hard to change shots between music differently.
This is Rooney getting sent off during a match. Dozens of cameras do a great job of spotting the action and using replays we are shown bits we missed, this is appealing because we get to see things from all angles.Events like football are always delivered in the same way so very little visual style is present.
This is QI, a popular quiz show presented by Stephen Fry.Cameras are position so there is one focused tightly on each panel member, then one on each side of the panel, one on the host and one far camera that sees the whole panel. This means there is always a camera on the right person, the best shot can be selected later when edited together.QI retains viewer interest most from the nature of the show and use of swapping cameras, it would be boring if their were one static camera.Its also got a lot of visual style mostly due to the vivid set and backdrop.
This is The Big Bang Theory, a popular TV series.The number of cameras usually depends on the number of characters on set, there is usually a close camera for each character and a few others for multi shots. The change between these along with the comedy keeps us interested.Its very easily recognisable most because of the characters themselves, certain occasional things hint as well though.
