A typical film scanner works by passing a narrowly focused beam of light through the film and reading the intensity and color of the light that emerges. [ 34 ]
Multi-Exposure – Multi-Exposure is an exposure blending technique for scanning transparent originals like slides, negatives, and film strips with increased dynamic range. [3] This is accomplished by scanning the original multiple times with different exposure times , increasing the dynamic range and preserving detail in the light and shadow ...

CIS of a flatbed scanner. Contact image sensors (CIS) are image sensors used in flatbed scanners almost in direct contact with the object to be scanned. Charge-coupled devices (CCDs), the other kind of sensor often used in scanners, use mirrors to bounce light to a stationary sensor.
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.
