5 True Tone and Night Shift
It’s termed “ambient light adaptive displays with paper-like appearance.” But you probably know it as True Tone. True Tone displays adjust to their surroundings to render onscreen images as they would be seen if printed on paper. In other words, white areas in an image might take on a warmer hue when in a room with incandescent lighting. The purpose of this is to achieve a more natural image.
Unlike True Tone, Night Shift is intended to automatically adjust the warmness of the display for use at night. Apple believes that increasing the warmness of the display after sunset can help make viewing easier on the eyes.
Pro Tip: When editing photos or video on your iPhone, iPad, or Mac you’ll want to make sure Night Shift is disabled. You may also want to make sure True Tone is disabled, although since it adjusts to the displays surroundings you may want to see what works best for you.
