Chapter 7. Working with Adjustment Layer... > Using the Reduce Noise Filter

Using the Reduce Noise Filter

The Reduce Noise Filter () helps to remove the random noise that crops up in digital images. It's called noise, but in reality is a pattern of distracting color or grayscale information that lays on the original image information. Noise can be generated by the Add Noise filter, but it typically comes from scanners and even digital cameras. Since there is a mathematical pattern to most noise, the Reduce Noise filter is designed to seek out and reduce the amount of noise in an image. The Reduce Noise filter works on individual layers, not the entire document. After applying the filter, you can use other restoration tools, such as the Healing Brush and Patch tool, to further clean up image problem areas.
