Allan Bell Posted March 28, 2017 Share Posted March 28, 2017 There is a new update for OS Sierra in 10.12.4 which among some useful updates includes something called "NGHT SHIFT". This has been around in IOS devices for a while but not on macs. Copy of article from "Mac Rumors" below. "Night Shift, the feature first introduced in iOS devices with iOS 9.3, has expanded to the Mac with the release of 10.12.4. Night Shift is compatible with 2012 and newer Macs, so it won't work on older machines. For those unfamiliar with Night Shift, it's designed to cut down on the amount of blue light you're exposed to during the evening by shifting the display of a Mac to a more yellow tone. Blue light is said to have a harmful effect on your circadian rhythm, making it harder to fall asleep and stay asleep. Studies suggest that eliminating blue light exposure at night might help you sleep just a bit better, but it does significantly change the look of your display. Many Mac users have been using blue light reduction software f.lux for years now, but with Night Shift, there's no need to install an additional app because it's an operating system feature." There is potentially a very bad side effect for photographers who like to work late in that the colours of any images worked on during the night time hours will not be correct due to the mac shifting the colour gamut automatically into the yellow area. So far I have not found any details, other than above, and no mention as how it could be switched off. This could obviously curtail our processing of RAW images unless a switch off command becomes available or, as will probably be the case, we find a work around. Comments please.
