There is a comfortable distance between camera to subject matter in scene and is determined by story point and emotional aspect; to arrived at this comfortable distance is a sense that is just as important as everything inside.
It’s an awareness that has direct affect to animation performance and timing sense.
A wrong fielding can really hurt a performance.
For example, take a situation that expresses an intimate conversation between two characters, a closer fielding would feel much fitting than a wider shot.

Likewise, when pencil testing, camera fielding should be set to intended field size. Timing and clarity of movement is closely linked to camera fielding; because a same movement will appear to travel faster and covering larger distance in close-up than in long shot.
As animator, one’s daily life often evolved around graphite lines and lacking visualization in colors; I find this limitation at time confiding. To remedy, I like to letting mind drifts, dreaming of isolated cinematic moments in quick color sketches; they might not be great, but they do stimulate the creative process… Now and then, from them came a new film idea… (It’s a good habit that I’m often in need to be reminded of doing.)
