Pictures are taken on iPhone using the Camera app. Locate the Camera app and tap it to open. On the capture screen, whatever is behind your camera will show. You need to hold your device to focus on the object to snap.

When you find out that the object appears clearly on your screen and doesn’t fall outside the edges, you need to tap the Round Capture icon to take a picture. Alternatively, you can press the volume buttons on your phone.
