Storyboarding - What is it?

Storyboarding is the visual idea of what a movie will look like, and is basically a comic book of the film before it is put into production. To the left is an example of a storyboard in its early stages. A detailed storyboard is essential for any film, as it means that shooting can go ahead if there is a last minute change of crew, or if something goes wrong on the day.
A good storyboard provides the director with an outline of what needs to be shot, as although he may have an idea of what he wants to shoot, he won't have thought of every single shot that is required. Storyboards are there as a sort of guideline, and often on the shoot day, directors will change elements in the shoot or alter the shot order if, on camera things don't look quite right.
