Use the Salt and Pepper Filter command to remove multiple-pixel black or white specks, such as those caused by dust on film or video. This command compares an area of pixels to the surrounding pixels and adjusts an area that is a speck to match those surrounding pixels.
To remove multiple-pixel specks:
Select the area that contains the specks. See Using the Selection Tools.
Choose Adjust > Add/Remove Noise > Salt And Pepper Filter.
Define the adjustment using the following options:
Speck size The minimum size, in pixels, of the largest speck that can be completely removed. The value is always an odd number.
Sensitivity to specks How different an area must be from its surrounding pixels to be considered a speck.
Mark the Include all lower speck sizes check box to have Paint Shop Pro remove all lower speck sizes. Results are usually better if you mark this check box.
Mark or clear the Aggressive action check box to set whether the strength of correction is normal (if the check box is cleared) or aggressive (if the check box is marked).
Click OK.
