Most scanners have multiple settings available for scanning slides, negatives, and photographs. When selected, adjustments are performed as part of the scan itself. Some settings should be used for almost every scan, while others should be utilized selectively.
Below is a summary of the value added by various settings:
|Setting||Description||Photographs||Film & Slides||Default|
|Backlight Correction||Removes shadows from photos that have too much background light||Yes||Yes||No|
|Color Restoration||Restores the color in faded photos automatically||Yes||Yes||No|
|Descreening||Removes the rippled pattern that can appear in subtly shaded image areas, such as skin tones||Yes||Not applicable||No|
|Dust Removal||Removes dust marks from originals||Yes||Yes||No|
|Grain Reduction||Reduces the effect of surface roughness||Not applicable||Yes||No|
|Unsharp Mask||Makes the edges of image areas clearer for an overall sharper image; if not selected, softer edges will result||Yes||Yes||Yes|
