Dust and scratch are common problems in Photoshop, and the Dust and Scratch filter can help to remove these artifacts. The filter is located in the Filter menu, and it is named after the two main types of scratches that Photoshop sees: dust and smudges. To use the Dust and Scratch filter, you first need to create a new layer on your canvas. Then, select the Dust and Scratch filter from the Filter menu. The filter will start to work on your layer, removing any artifacts that have been created by your previous filters. If you have any problems with the Dust and Scratch filter, be sure to experiment with different settings until you find one that works best for you. Be sure to keep a close eye on your results so that you can make necessary changes if needed.
