 DIT ( Digital Image Technician)

The Digital Imaging (or Image) Technician is a relatively new position on a motion picture set. The position was created as a response to the transition from the long established film medium into digital cinema, which utilizes various formats like HD, 2K, and 4K. Since video reacts much differently than film in many situations, the DIT's job is to work with the cinematographer and help achieve the best results. This includes but is not limited to: monitoring exposure, setting up "look up tables" (LUTs), set camera settings, and media management.
