What is Apple’s True Tone technology in the MacBook Pro 2018, and why is it important?



Apple's MacBook Pro update revealed on Thursday that Apple has incorporated True Tone technology into a Mac's screen for the first time. AppleInsider sheds some light on the color management system that aims to keep the image the same for the user, wherever it is.

The announcement of the 2018 MacBook Pro line included a series of notebook alignment changes, with major changes including support for up to 32GB of memory, 8th generation Intel Core processors and up to 4TB of SSD storage . Other important changes include a new quieter keyboard, the use of the Apple T2 chip for added security and the addition of "Hey Siri" support.

As part of the updates, the screen also received some attention. In addition to the 500 nits of brightness and the wide range of P3 colors, the screen also uses Apple's True Tone technology, which marks its first appearance on an iMac or MacBook screen.

What is True Tone?

Introduced for the first time in the Apple ecosystem with the 9.7-inch iPad Pro, True Tone is Apple's system for maintaining the white balance of the screen in appearance for the user, regardless of the light environment around it. the screen. When the device moves from one environment to another, the user perceives that the screen is "the same" at all times.

Normally, when the ambient light changes in an environment, the white balance and the overall color of the screen appear to change, for example, becoming more blue or orange, even if the screen settings remain the same. This is actually a problem caused by the user's own vision, due to observing the change in the rest of the lighting conditions of the environment and adapting to that, while also observing the "modified" screen.

True Tone combats the problem by using four-channel sensors to detect ambient light that can affect the perception of the screen. If a change is detected, such as the user moving an iPad Pro from a room illuminated with cool blue bulbs to more yellow light outside on a sunny day, the screen automatically alters what it shows to match, keeping the screen comparably similar to despite the different situations of light.

Why use True Tone?

For the most part, True Tone is intended to make the experience of using the device more comfortable for the user. Matching the light scheme of the environment can help prevent any tension or discomfort for the user by seeing a screen suddenly blue or orange, which also changes constantly if they move.

Another reason is to minimize the amount of blue light a user might be exposed to during their workday. It is believed that overexposure to blue light can disrupt a user's sleep patterns.

The color scheme also helps create a situation where the user's perception of a Color on the screen is the same regardless of its surroundings. Apple called this a "paper-like" visual experience, since it is an effect similar to seeing a drawing on white paper, and how it appears under different lighting situations.

Will it affect users in the creative professions?

There may be some concern for users in industries where visual appearance is important, such as video editing, illustration and photography. These creative professions already have to deal with color problems, such as making sure that different screens show the same image with identical colors.

On Apple systems, this has been largely managed by the ColorSync color management tool, which helped maintain accurate color representation between desktops. This only solved part of the problem, because although the colors shown on the connected screens could be precise, the problem of human perception returns, since it does not take into account the environment and may seem "incorrect" for the user.

As True Tone handles the ambient lighting problem, this should make it easier for the user to see their I work in different conditions and perceive it in the same way. As a technology that specifically affects the screen, it does not directly interact with applications or files in any way, since it only changes what the screen finally shows the user.

This also potentially allows creative users to work under a variety of lighting conditions, without greatly affecting the tasks related to color. For example, when applying color to an illustration, the same "red" color perceived in an environment will appear to be the same "red" if the user opens the file under different conditions.

Can I try it?

Depending on your investment in the Apple ecosystem, you may be able to try True Tone for yourself, before disbursing for the 218 MacBook Pro. It has been available for some time on the 9.7-inch iPad Pro, as well as on the iPad Pro 10.5 inches and iPad Pro 2017 12.9 inches.

You can also try it if you or someone you know owns one of the iPhones of the current generation of Apple. The iPhone X, iPhone 8 and iPhone 8 Plus use True Tone on their screens, which can be enabled and disabled from the Settings menu.

Considering its appearance on the MacBook Pro 2018, as well as rumors and speculations, it is possible that Apple will incorporate the technology into other screens of Pro-grade products in the future, such as the upcoming Apple Pro screens.
