An addition to the design of the iPhone 16 Pro and Pro Max is the physical camera control button, it gives users swift access to different camera functionalities. Tapping it once opens the camera, tapping it more gets you a picture, and a long press starts a recording. Gentle presses allow you to change various settings like the exposure, depth, zoom, and camera styles. You may also change between the cameras set on the 'two cameras' mode. It takes a little while to learn it but once you do it’s very convenient and a valuable enhancement of the iPhone.
