Dust and scratches on the film can be a big problem for scanning. Because of their reduced size (compared to prints), the scanners are capable of resolutions much higher than a regular flatbed scanner; typically at least 2000 samples per inch (spi), up to 4000 spi or more. At these resolutions dust and scratches take on gigantic proportions.
