Timesheets
A timesheet (exposure or dope sheet) tells the camera department exactly which drawings and cel layers to expose on each frame, together with dialogue timing and camera instructions. It is the score that turns stacks of static cels into motion.
Correction sheets
A correction sheet (shūsei, 修正) is a drawing made by an animation supervisor or director over an animator's work, showing how a pose or drawing should be fixed to stay on-model or improve the acting. Correction sheets are collected because they reveal the guiding hand of the people who shaped a production's look.
What to look for
- Timesheets: grids of frame-by-frame columns marked with drawing and layer numbers.
- Correction sheets: a second, authoritative drawing (often in red or blue) laid over or beside the original.
