How to Adjust Image Brightness and Contrast in Dreamweaver

Dreamweaver provides you with tools to make image adjustments, including the brightness and contrast. Adjusting an image's brightness allows you to change the overall amount of light in an image. Contrast controls the difference between the light and dark areas of an image.

Using Dreamweaver’s editing tools permanently alters the image when the page is saved. If you're concerned, the best thing to do is to make a copy of the image and make your adjustments to the copy.

To adjust brightness and contrast, follow these steps:

  1. In the Document window, select the image you want to alter.

    The Property inspector shows the image properties.

  2. Click the Brightness and Contrast icon.

    A dialog box appears, indicating that the changes you make will affect the original file.

  3. Click OK in the Dreamweaver dialog box.

    The Brightness/Contrast dialog box appears.

  4. Use the sliders to adjust the brightness and contrast settings of the image.

    Make sure to select the Preview check box if you want to see how the changes affect the image as you move the sliders around.

  5. Click OK.

    The settings take effect permanently when you save the page.
