Digital Picture Exchange
The Digital Picture Exchange (DPX) is the usual file format for modern feature film production using the digital intermediate process.
The file format is designed to process large amounts of contrast, which are typical for digital cinema cameras or film material. Each color channel is saved with up to 32 bits (linear or logarithmic). A widely used device for film scanning for digital processing, for example, supplies data in 10-bit logarithmic form, which fully covers the contrast range of 16mm material. Professional systems for compositing or color processing work natively with the DPX data, which can also be used at the end of the production chain to expose the content on film.
It is standardized according to ANSI / SMPTE ("SMPTE 268M-2003, v 2.0"), which goes back to the draft standard ANSI / SMPTE 268M-1994, v 1.0.
