DPX (Digital Picture Exchange)

The DPX format, introduced in 1994, is an image format used mainly for visual effects and for storing digital intermediate work. The format is derived from the Kodak Cineon format, originally devised for use in digital cameras.

The format is most commonly used to store image color density data and is the chosen format for storing still frames for use in post-production work. The format is still used today, with the format receiving its latest update in 2018 and can be opened in some 3rd party image processing software.
