Its built-in retouching technology handles the most common problems found with old negatives and slides. It can remove much of the dust and scratches that may appear on your originals. It can also revive images that have faded over time. Plus, Backlight Correction Technology works to adjust image exposure, and Grain Correction will help smooth out grainy images.
