Animation is great because it integrates so many creative and technical fields and what you can do with it is limited only by your imagination.  The best animation takes a team, everyone doing their part as perfectly as possible.

Animation involves the precise coordination of many moving parts: good ideas, the drawing, clay or other objects that will carry out the ideas, an unmoving camera that frames and focuses on the well-lit action below, a steady hand, the smooth transfer of the frames (stills) to the computer, a skilled editor to bring out the best in the frames, a good soundtrack to make it all dance.

It takes free play and also concentration and focus.  Without great attention to detail, the resulting animation will be unwatchable.  It takes precision to keep everything the camera sees registered for the illusion of movement.  It takes patience and mastery to make the adjustments necessary to correct mistakes.   In the midst of a buzzing beehive of children busy having fun, coordination, focus and teamwork are required to make good animation.

Picture the greatest drawing in the world, and the most skillful editor in the world. Then picture all the frames of these great drawings are dark, because not properly lit. Or fuzzy, because nobody took the time to focus.  Or badly framed, because somebody was too excited about shooting something to carefully line things up.  The great drawings are ruined, all the skill of the best editor in the world won’t be able to turn those frames into watchable animation.

Got to shoot the whole thing over again, carefully.   There is an art to it, and various skills to be mastered.   And it takes a team, everybody doing their part, and doing it well, and helping each other along the way.   

That’s why animation.
