Exposure sheet

An exposure sheet (also referred to as camera instruction sheet, dope sheet or X-sheet) is a traditional animation tool that allows an animator to organize their thinking and give instructions to the camera operator on how the animation is to be shot. It consists of five sections, and is a bit longer and a bit narrower, than A4. Every eighth line down is marked thicker than the rest and shows half a foot of film. One second of animation would take three of these sections. Sound breakdown was often done on separate sheets called bar sheets made by the editor, and given to the animator who would transpose them to his dope sheet.
