# Modifying Exposure and Contrast in the Image Display

You can modify the overall brightness of images displayed on the workstation or broadcast monitor, as well as the contrast between light and dark colours. Note that these settings affect only the display, and do not modify the underlying colour values of the clips.

To modify exposure and contrast interactively in an image window

1. Click in an image window to make it active.
2. Do any of the following:
   - Press and hold Shift+E while clicking and dragging the mouse to modify the exposure offset (overall brightness). Dragging to the right increases values and dragging to the left decreases them.
   - Press and hold Shift+C while clicking and dragging the mouse to modify the contrast between light and dark colours.
   - Click Reset to restore the default values.

To modify exposure and contrast using the Image Display settings

1. Access the Image Display Viewer settings.
2. Do either of the following:
   - Edit the Exposure slider to modify overall brightness.
   - Edit the Contrast slider to modify the contrast between light and dark colours.

NoteIf you have applied a colour transform to the display, then you cannot modify the exposure and contrast unless there is a dynamic ExposureContrast operator in the CTF file.
