Try the New Camera Control
All the new iPhone 16 models except for the iPhone 16e come with a new button called Camera Control.
As you can guess by its name, you can use it to do all sorts of things with your camera. For instance, if you press it once, your iPhone will instantly open the Camera app. Press it again, and it will take a picture. Press and hold it while in the Camera app and your iPhone will start recording a video that will last until you release the Camera control.
However, there’s more that you can do with this button. As you probably noticed, the Camera control isn’t just a button; it also has a touch-sensitive surface that can detect the amount of pressure you use. You can use this to change basic camera settings more quickly and easily.
All you need to do is lightly push the Camera Control button — without fully pressing it — and you’ll see a small menu pop up right below the bottom. You can then swipe to the left or right to change the settings. By default, you should see the options to zoom in and out of the frame, but if you swipe the small menu down, you’ll get another list of settings you can change with the Camera Control.
Granted, changing these settings using the Camera app might be more comfortable, but this allows you to quickly change a couple of basic settings without the risk of losing the shot you want to take.
