Ymagis Group and Eclair are thrilled to publish our White Paper on the new HTM (Hybrid Tone Mapping) technology, which enables the optimized storage of two or more versions – SDR (Standard Dynamic Range) and HDR (High Dynamic Range) – of a same feature film in a single SMPTE-compliant (Society of Motion Picture & Television Engineers) DCP (Digital Cinema Package).
The patent-pending HTM solution offers a multi-display DCP (MD DCP – Multi-dynamic Digital Cinema Package) that comes with a special software, MD Map (Multi-dynamic Mapping), that is easily integrated in projection systems through regular updates, as well as current and future LED displays. MD DCPs are fully compatible with all types of projection systems and LED cinema screens.
By incorporating specific settings in the DCP, the same content can be played via a standard projection system in SDR format as well as in HDR, whether the equipment is an EclairColor HDR-certified projector or simply HDR-ready. HTM technology allows the system to read the same group of files by automatically selecting the correct version of the film that matches the projection systems’ or existing LED displays’ technical specifications.
Each version of the film gives filmmakers full artistic control over the content knowing that the HTM technology combines an automatic adaptation of the signal with the settings done by the color grader at the postproduction stage.
