Many high-quality scanners, including both flatbed and dedicated film scanners, have the ability to adjust the focus of the optics. This allows the scanner to offset the focus up or down by several millimeters from the regular focus level. Some scanners have automatic focus control, while others also allow the user to manually set the focus.
Using the Focus Control feature in SilverFast can help ensure you get crisp, sharp scans – even with materials that don't lie perfectly flat on the scanner.
