Digital Imaging Technician
1. On digital photography productions the Digital Imaging Technician, or DIT, is responsible for the coordination of the internal workings of the digital camera. Under the direction of the Cinematographer or Director of Photography, the DIT will make adjustments to the multitude of variables available in most professional digital cameras to creatively or technically manipulate the resulting image. It may also be the responsibility of the DIT to archive and manage the digital data, create compressed dailies from raw footage and prepare all digital images for post-production.
