Macro - definition
Macro is a mode of the camera in smartphones to capture a small and closer object with more focus and detail. Usually when taking a picture of small objects such as insects, flowers, or related objects the camera should be switched to the macro mode to get more detail and clear photos. In modern devices, a different lens is used to detect the camera mode automatically, it is called a Macro lens. If switched to Macro mode then infinity focus doesn’t work which means you won’t be able to capture any photo further than a specific distance.
