Apple Display P3

If you are somewhat new to the above title (as I was) you may appreciate this very brief and non-technical bit of info.

In 2005 as movie distribution was evolving to become all digital, a need arose to standardize and upgrade theatrical colour reproduction. An organization known as the Digital Cinema Initiative released a new RGB colour space for digital movies called DCI-P3 which was realized in xenon-arc theatrical projection systems.

As the production/special effects industries use computers to produce these movies, a further need arose to develop a wider gamut rgb colour space for computer monitors. The computer industry adapted DCI-P3. Apple’s adaption of DCI-P3 was called Apple Display P3 and first appeared in an iMac in 2015. Since then Apple have introduced this new colour technology to more of their products, including phones. New Macbook Pros have Apple Display P3. Basically new Macbook Pros have a screen which displays Adobe RGB! I say this because although it is technically not Adobe RGB, Apple Display P3 has very similar specs (D65 white point, 2.2 gamma and a very similar colour gamut). It also acts the same way as Adobe RGB does in Adobe’s suite of apps (if you choose to use it over sRGB of course). That is it acts like Adobe RGB in that it is a central background colour space which hosts and interprets the ICC colour profiles embedded in your files. The Apple Display P3 is included in the operating system and backed up by the Apple hardware.

The big thing for old timers like me is to get a display which actually shows the Adobe RGB colour gamut, as this cost many thousands of dollars in even the recent past and was offered by very few manufacturers. These monitors were few and far between and especially prized by printers for showing them accurate colours upfront in conjunction with colour management.

The Apple Display P3 colour gamut reportedly has a slightly deeper red capability than Adobe RGB and a slightly less deep cyan. Basically they are the same.
