Exposure Sheet

You use the Exposure Sheet window work on the timing of elements. The exposure sheet is similar to the paper exposure sheets traditional animators use to lay out layers, or elements, in 2D cel animation.

The Exposure Sheet window organizes drawing, image, sound and media elements into columns.

Columns to the left appear on top of columns to the right. You should put your background elements in the right columns of the Exposure Sheet window.
The layering order in the Exposure Sheet determines the composition order when you export or play back your animation from the Exposure Sheet.
The layering order of the columns also determines how the elements appear in the Auto Light Table.

The Exposure Sheet serves a different purpose from the Timeline window.

The Exposure Sheet displays the breakdown of elements in each frame of your animation. It shows the contents of each cell in an element, as well as their order and timing.
Unlike the Timeline, which allows you to track entire element layers, you can use the Exposure sheet to display thumbnails of images as they appear in each frame, including the lip chart, which can help you visualize your scene and its contents.

The Exposure Sheet window also has two panels you can use to help you work with elements and drawings:
