Affecting brightness and contrast
Digital photography has opened the floodgates for posting images on the Web. Unfortunately, not all images
look as good as they might. If you want to make the graphic lighter or darker or perhaps use a little more
contrast, Dreamweaver has just the tool you need. The Brightness and Contrast command offers independent
control over the two interlinked aspects of an image. Best of all, the Brightness/Contrast dialog box
offers a Preview option, as shown in Figure 9-9, so that you can see the changes to the image in real time.

Preview the changes when using the Brightness and Contrast control to make sure you??™re getting the effect you want.
To alter the brightness and/or contrast of an image, follow these steps:
1. Select the image you want to modify.
2. Click the Brightness and Contrast button on the Property inspector. Dreamweaver displays the
Brightness/Contrast dialog box.

3. Make sure the Preview box is selected to see the changes applied as you move the controls.
4. Drag the Brightness slider to the left or right; dragging the slider to the left lowers the brightness;
dragging it to the right increases brightness. Alternatively, you can enter a value directly in the
Brightness field.
