D.I.T.

"A digital imaging technician (DIT) works in collaboration with a cinematographer on work flow, systemization, signal integrity and image manipulation, to achieve the highest image quality and creative goals of cinematography in the digital realm.[1]
A DIT's role is especially prevalent with the widespread use of HD technology, in assisting cinematographers normally accustomed to film stock in achieving their desired look. They may also be in charge of transferring and managing the image data, replacing the traditional film loader position.
The Digital Imaging Technician (or D.I.T.) (or Digital Image Technician) is a relatively new position on a motion picture set. It was created as a response to a transition from the traditional film medium into Digital formats such as High Definition Video. Video reacts differently than film in many situations. Better or worse is really up to the viewer. The fact still remains that the image is different and so is the method of achieving the best quality possible. The D.I.T.'s job is to work with the Cinematographer and help achieve the best results. This includes but not limited to: monitoring exposure, setting up "look up tables" (LUTs), set camera settings, etc... In the end, the image integrity is the main focus."
