[1] The DIT is the camera department crew member who works in collaboration with the cinematographer on workflow, systemization, camera settings, signal integrity and image manipulation to achieve the highest image quality and creative goals of cinematography in the digital realm.
The DIT's role on-set has become especially prevalent through assisting cinematographers, normally accustomed to film stock, in achieving their desired look digitally.
This is accomplished by the DIT through monitoring picture exposure, setting up Color Decision List (CDL) on daily basis and, if requested, "look up tables" (LUTs) for the post-production.
Additionally, the DIT handles any settings in the digital camera's menu system, such as recording format and outputs.
[4] In tradition with the classic role of film loader, the 2nd AC may alternatively take on the responsibility of digital loading as an additional duty.
