As an artist, I always wish for unlimited budgets and unlimited time to craft my work. But as a businessman I have to squeeze every dollar I get. You only have so much money in your budget. The funds have to be spread out. Where do you put your money?
For me the important elements are: story, design, and the planning of key animation scenes. So, I look at everything I do with an eye on getting the most out of every drawing I make.
This affects my decision regarding animation choices such as:
1) Putting an action on one frame exposure or two frames.
2) Do I level the body as a held cel or trace it continually for several drawings? Or do I run a cycle of three traced back bodies to maintain a flicker of "life"?
3) Can I reuse a strong action several times in different scenes by changing the fielding and/or flopping the drawings to move in the opposite direction? And so on.
It doesn't hurt the artist in me to be creative in searching for solutions that will help the businessman in me to pay the bills. In fact, I believe it forces the artist to focus on what is important in the scene.
The following is a short "Rant"
For me, creating an animated film is like baking a cake and icing it. There are so many elements that go into the process that, if the baker doesn't use the right ingredients and proportions, the cake can easily be ruined. For me, the most important part is the body of the cake, not the icing. A simple layer of icing on a tasty cake is a wonderful touch, but it isn't the most important element.
However, now that film producers have the computer technology to put up on the screen almost anything one can imagine, they spend fortunes on making beautiful icing, but insist on using it to cover very substandard cake.
In fact, for me the vast majority of today's animated features (and live action films) are all icing and no cake.
