Flash photography is a technique that uses a brief burst of artificial light to illuminate a scene or subject. This method is particularly useful in low-light conditions, helping to capture clear images without relying solely on ambient light. The flash can be built into the camera or used as an external device, allowing for greater flexibility in lighting. When using flash photography, it's important to consider the distance between the flash and the subject, as well as the flash's power settings. Properly adjusting these factors can prevent overexposure or underexposure, ensuring that the final image accurately represents the scene.
