WHAT IS “STORYBOARDING”?

According to http://www2.hawaii.edu/~ricky/etec/whatis.html#anchor952161 a storyboard is:

Something that is made before the “production” stage, also used during the production and after the production. It is a sequence of pictures that are used to show the “construction” of a video part. Each drawing has: a draft of the video image; a simple description of the image; notes for the camera operator; the details of the sound that will go together with the image; and an estimation of how long the part will be.
