Night vision is a critical function for security and surveillance. iPhone 11 has a new feature called Night Sight that makes it easier to use night vision on your device. To enable Night Sight, you need to first enable the camera in the Settings app. Then, you need to set up your camera’s night vision settings. To do this, you’ll need to find the Camera icon in the top left corner of your screen and select it. Next, you’ll need to set up your night vision settings. To do this, you’ll need to find the Camera icon in the top left corner of your screen and select it. In the Camera settings, you’ll want to set up two things: Resolution and Frame Rate. Resolution is how many pixels per inch that your camera can see; Frame Rate is how often the camera will take pictures per second. Now that you’ve set up your night vision settings, you’re ready to start using Night Sight on iPhone 11! To start using Night Sight, just open an image or video file and pressand hold until it starts playing automatically. When Night Sight starts working, it will show a green light next to each picture or video thumbnail that it captures.
