In traditional and paperless animation, it is useful to plan your scene by creating its exposure before creating the drawings. The most basic method of creating a scene's exposure is by manually entering the name (typically a number) of each drawing in each cell of each column in your scene using the Xsheet view. However, Harmony has many tools allowing you to streamline the exposure filling process. If you plan to animate on twos or threes, Harmony can automatically expose each drawing added to your exposure sheet over the preferred amount of frames. You can also fill a range of cells with the same drawing, a number sequence, a cycle, or even random drawing numbers.
