Full-length feature films for the cinema have been produced by photochemical methods for over 100 years, based on a three-step workflow: original photography, post-production, and release printing. In the last decades of the 20th century digital methods were
first introduced for limited special-effects tasks, and subsequently adopted for many routine processes in the post-production phase of the workflow. Improvements in imaging technology are enabling feature-quality digital methods to be used in all three steps of the traditional motion picture
workflow, as digital capture, digital intermediate, and digital cinema projection, respectively. This paper describes how digital methods are being incorporated into motion picture production, with a particular focus on color reproduction issues.
