The first big change affects the function of adaptive brightness control. This option is used to save battery in portable devices, reducing the maximum brightness of the screen if something is shown for example with a white background. This is only available for devices with the Content Adaptive Brightness Control (CABC) feature, and the problem is that its implementation was causing problems. Among them, we found that color accuracy could be affected, making it impossible to retouch photos correctly.
Adaptive brightness and camera changes
Therefore, update 21H2 will finally allow deactivating this option in the screen settings within the Settings menu. There, we find a new box to deactivate the option «change brightness automatically when lighting changes«.
The second big change affects cameras. The application of Windows 10 Camera it is quite comfortable and easy to use, allowing us to quickly record video at the resolution and frames we want with the camera we connect. However, it does not allow many adjustments to the camera itself, and with 21H2 we will finally be able to change several of those settings.
To begin with, we can choose the camera we want as the default device in the event that we have several connected. In turn, we can also adjust brightness and contrast from the settings section, ideal to compensate if there is a very strong contrast in the room or if it looks too dark. We also have an advanced settings section where you can adjust the camera rotation, activate HDR mode in Windows, and activate the Eye Contact function.
Windows will alert us if someone is using the webcam
The webcam also receives the third big change, and that is that now the operating system will notify us when there is a program or application accessing it. Currently, when an application accesses the microphone, the operating system notifies us in the task bar with a microphone icon, but this did not happen with the camera. Now, an icon of a camera will appear, as well as the name of the application that is accessing the camera. Thanks to this, our privacy will be fully guaranteed at all times if we have a webcam with a microphone.
Other minor changes are the introduction to more users of the time bar at the bottom right, in which, if we click, it will also show us recent news of the day. To test all these novelties in the stable version of Windows 10 we will have to wait at least until autumn.
