![]() A zoom wheel will appear, and you can slide your finger left or right to switch to the 13 mm, 26 mm, or 52 mm lenses and the digital zooms available. In the Photos mode in Camera, tap-and-hold the 0.5x or 1x for the iPhone 11, or the 0.5x, 1x, or 2x for the 11 Pro models, depending on which is currently in use. Don't Miss: Turn Off Live Photos Forever on Your iPhone's Camera App.Regardless of your iPhone model, however, it only works in specific shooting modes. While other iPhone models also work with the gesture, their controls will look differently depending on if they have one or two lenses for the rear camera system. While you can pinch in and out on the screen to control the zoom, there's a way to get more granular control for photos.Īs long as you have either an iPhone 11, 11 Pro, or 11 Pro Max running iOS 13, you can use a quick gesture to access the granular zoom controls to define the focal length of your camera better. ![]() So you can zoom anywhere between 0.5x optically to 5x or 10x digitally, depending on the one you have. ![]() On top of that, the Pro models also have a telephoto lens. As the human visual system uses both size and perspective cues to judge the relative sizes of objects, seeing a perspective change without a size change is a highly unsettling effect, often with strong emotional impact.The iPhone 11 series models have sophisticated camera systems that include both a wide and ultra-wide lens. The visual appearance for the viewer is that either the background suddenly grows in size and detail and overwhelms the foreground, or the foreground becomes immense and dominates its previous setting, depending on which way the dolly zoom is executed. Hence, the dolly zoom effect can be broken down into three main components: the moving direction of the camera, the dolly speed, and the camera lens' focal length. Thus, during the zoom, there is a continuous perspective distortion, the most directly noticeable feature being that the background appears to change size relative to the subject. The dolly zoom's switch in lenses can help audiences identify the visual difference between wide-angle lenses and telephoto lenses. In its classic form, the camera angle is pulled away from a subject while the lens zooms in, or vice versa. The zoom shifts from a wide-angle view into a more tighter-packed angle. The effect is achieved by zooming a zoom lens to adjust the angle of view (often referred to as field of view, or FOV) while the camera dollies (moves) toward or away from the subject in such a way as to keep the subject the same size in the frame throughout. ![]() In the video inset, the object moves with the camera and it does not zoom, so the FOV does not change thus there is no dolly effect At the bottom of the image is a plan view showing the camera moving back while zooming in, illustrating how the effect is achieved. At the top of the image is the camera's view the cubes stay the same size as the teapots in the background grow bigger.
