In my case, as an independent film maker, I am just about everything else in the production pipeline, too--but never mind about that.
When I am the Storyboard Person and I come to a scene where my thinking is engaged in the development of a scene, sometimes the Animator takes the pencil away from me and adds some "unnecessary" panels to the board.
Of course they are not entirely unnecessary--not at all. But they are perhaps not necessary to the storyboard as such; they are instead necessary as thumbnails for the animator. Thumbnailing your animation ideas is considered an essential step for the animator in visualizing all the action of a scene before more detailed work is begun.
I do consider not including these more subtle stages of movement, but when I do, the Animator jumps to his feet in great agitation, saying, "Wait! Having thought of these details, how can you not set them down? What if, by the time I, the Animator, at last get hold of the scene, I do not recall these inspirations that have occurred to us, and instead do something with the movement of this character that is less interesting than what we have thought of here? Then, having not recorded these fleetiing but wonderful notions, they will be lost."
And so I find that I, the Storyboard Person (Storyboardist? Why is there not a one-word term for this art? Even Inbetweener, awkward though it is, is but a single word) cannot argue with the Animator in this. If you think it, if you like it, write it down or draw it; make a note of it. Because, you see, if you think of it and do not record it, and then you forget the thought that you had, you may even forget that you had any idea at all. You will not even know that anything is missing. Why take that chance?
Following is a part of a scene that might have been depicted satisfactorily in just five panels, storyboard-wise. But for the sake of the Animator, I (the Storyboard Person) have included some extra stages of movement.
|The first panel, the first pose.|
|He pushes open the lid; an essential panel.|
|Reaching into the lid; another essential panel.|
|In this panel and the next, the man unsuccessfully tries to pull something out|
of the lid, This might be something that the animator and not the storyboard
person would be adding.
|The Old Man now takes a two-handed grip.|
|This drawing clearly could be omitted from the storyboard, if not from the|
notes of the animator.
|This panel is another essential, showing the flow of the big overcoat as it|
emerges from the lid of the trunk.
|Another panel not essential to the storyboard. One can easily get the whole|
idea of the action without these two sepia-colored panels.
|The final essential panel.|
