# Changing the Timing (Exposure) of Drawings and Images

The amount of time a single frame appears on screen depends on the animation’s frame rate. If the frame rate is 12 frames-per-second (fps), then each frame appears for 1/12th of a second.

You can change the exposure of a drawing, image or media to increase or decrease the amount of time it spends on screen. For example, you can extend the exposure of a drawing from 1 to 3, the drawing will appear on screen for 3 times as long.

To extend the exposure of a drawing or image in the Exposure Sheet:

1. Click a labelled cell in the Exposure Sheet.

2. Hold the mouse and drag the bottom of the cell to the last frame you want the drawing or image to appear in.

3. Release the mouse button.

To change the exposure of a drawing or image:

1. Select the cell of the drawing, image or media element.

- In the Exposure Sheet window, click the cell.
- In the Timeline window, click the cell. If the Single Cell Selection preference is not selected, press the [Option] button as you select a cell.

2. Select one of the following commands from the Element > Cell menu.

- Set Exposure to 1: appears in one frame (the default setting)
- Set Exposure to 2: appears in two frames.
- Set Exposure to 3: appears in three frames.
- Set Exposure: to set another exposure time. This command opens the Set Exposure dialog box.
- Add Exposure: adds one to the drawing, image or media’s current exposure time.
- Remove Exposure: removes one exposure from the drawing or images current exposure time.
- Extend Exposure: adds a selected number of frames to the current exposure time. This command opens the Extend Exposure dialog box.

| Here’s a shortcut for extending the exposure in the Exposure Sheet window. Selecting the cell that you want to extend the previous drawing’s exposure time to. Select Element > Cell > Extend Exposure.
