A lightning symbol appearing within a smartphone’s camera interface represents the flash function. When enabled, this feature triggers a burst of artificial light concurrent with image capture. For instance, selecting this icon before pressing the shutter button causes the camera’s LED to illuminate, providing supplemental light in low-illumination environments.
This capability is vital for improving image quality in dimly lit scenarios. It allows users to capture brighter, more detailed photographs that might otherwise be underexposed or blurry. The integration of this function into mobile devices has democratized photography, enabling individuals to document moments previously inaccessible to point-and-shoot cameras.
