Photography and graphic technology -- Extended colour encodings for digital image storage, manipulation and interchange -- Part 2: Reference output medium metric RGB colour image encoding (ROMM RGB)
ISO 22028-2:2013 defines a family of extended colour-gamut output-referred RGB colour image encodings designated as reference output medium metric RGB (ROMM RGB). Digital images encoded using ROMM RGB can be manipulated, stored, transmitted, displayed, or printed by digital still picture imaging systems. Three precision levels are defined using 8-, 12- and 16-bits/channel.
