You can use Auto Levels to have Fireworks make tonal range adjustments for you.

To adjust highlights, midtones, and shadows automatically:

  1. Select the image.
  2. Do one of the following to select Auto Levels:
    • In the Property inspector, click the Add Live Filters button, and then select Adjust Color > Auto Levels from the Filters pop-up menu.
    • Select Filters > Adjust Color > Auto Levels.

    NOTE

    Applying a filter from the Filters menu is destructive; that is, it cannot be undone except when Edit > Undo is an option. To maintain the ability to adjust, turn off, or remove this filter, apply it as a Live Filter, as described in the first bulleted option in this step. For more information, see Using Live Filters.

    TIP

    You can also adjust highlights, midtones, and shadows automatically by clicking the Auto button in the Levels or Curves dialog box.
