The Importance of Digital Intermediate and Its Production
Digital Intermediate (DI) is gradually replacing the traditional intermediate produced by the Laboratory. When producing DI, the original image is scanned as DPX files. A scanner sees the film transmittance and scans with a higher spatial resolution than the output format to avoid aliasing. There are two different ways of image encoding in the DI process. One uses DPX files which represent negative film densities. A display LUT is required to render a preview of the image. The other way is to directly display the image data. The data needs to be converted into density values before it is recorded to film and the recorder needs to reduce the red gamma of Status M data during recoding. If the printing densities are correctly translated, a print from the DI will match a print from the original negative. The paper describes in detail the importance of DI and its production.
