Dust & Scratches

Settings

The following settings can be adjusted on the context toolbar:

• Radius—controls the size threshold for determining dust and scratch artefacts. If the artefacts are mainly fine in detail, use a smaller radius. Larger radius values will tackle larger artefacts.
• Tolerance—determines how aggressively the filter should analyse the image. Increase the slider to reduce the amount of the image that the filter will affect.
• Channels—when checked, the Tolerance works on a per-channel basis. Useful for colour images as it can produce smoother results and fewer artefacts.
