Acceptable values are from ??“100 to 100, with 0 being the default.
5. Move the Contrast slider to the right to increase the contrast or to the left to decrease it.
Alternatively, you can enter a value between ??“100 and 100 in the Contrast field.
6. When you??™re finished, click OK.
Although Brightness and Contrast is most frequently associated with photographic JPG images, it can also
be used for GIFs. However, be careful if your GIF has a transparent area; altering the brightness and/or contrast
too much could make the transparent area visible.
Sharpening graphic lines
In Web applications, fuzzy logic is generally sought after, but fuzzy photos are not. You can clear up blurry
images with Dreamweaver??™s Sharpen command found on the Property inspector.
The Sharpen command examines the edges found within a graphic and programmatically increases the contrast
of the related pixels. Flat areas of color are left unaffected. The Sharpen dialog (see Figure 9-10) offers
a sliding scale from 0 to 10 where 10 represents the maximum amount of sharpening available in one operation.
As with the Brightness/Contrast dialog, you can select the preview option.
FIGURE 9-10
Bring your images into focus with Dreamweaver??™s Sharpen feature.
If you??™re using Fireworks and need more sharpening power than Dreamweaver offers, try
applying the Unsharp Mask in Fireworks.
