Removing dust and scratch marks from bitmaps

You can quickly improve the appearance of a bitmap by removing dust and scratch marks. The dust and scratch filter works by eliminating the contrast between pixels that exceed the contrast threshold you set. You can set a radius to determine how many pixels are affected by the changes. The settings you choose depend on the size of the blemish and the area surrounding it. For example, if you have a white scratch that is 1 or 2 pixels wide on a dark background, you can set a radius of 2 or 3 pixels and set the contrast threshold higher than if the same scratch was on a light background.

radius as low as possible to retain image detail.

• Threshold — lets you set the amount of noise reduction. Set the threshold as high as possible to retain image detail.
