A shoot day is a plan with weather in it.Cinema camera, lighting, sound, and a crew staffed for the day that happensrather than the day that was written down.Events do not wait and they do not repeat.Coverage is planned for the moments that occur once,which means deciding in advance what can be missed.The camera is the cheapest thing on the call sheet.The expensive part is the hour nobody planned for.One producer runs the floor. One crew, no vendors waiting on each other.Everything that could be decided in advance already has been.What is left for the day is the work itself.
