Using the Sharpen feature to sharpen an image
You can use the Sharpen feature to correct images that are blurry. Fireworks has three Sharpen
options:
adjusts the focus of a blurred image by increasing the contrast of adjacent pixels.
Sharpen
increases the contrast of adjacent pixels about three times as much as Sharpen.
Sharpen More
sharpens an image by adjusting the contrast of the pixel edges. This option offers
Unsharp Mask
the most control, so it is usually the best option for sharpening an image.
