Calibration and validation of motion picture scans

A method of calibrating digital images or digital video clips representative of images and/or data stored on or with one or more frames of a film comprising:

• imaging the film using a film scanner to obtain scanned images or video clips;
• placing a transparent calibration pattern in front of or behind a film so that a portion of the transparent calibration pattern is imaged through perforations in the film to form an imaged calibration pattern, the width of the calibration pattern being less than the width of the perforations running up and down sides of the film so the calibration pattern is imaged through the perforations;
• and
• determining scanner exposure variation using the imaged calibration pattern,
• wherein each digitized image of a frame of the film has at least some calibration pattern visible through one or more perforation;
• and
• wherein the calibration pattern remains in the digitized image of every frame of the film.
