Flash photography involves the use of artificial light sources, such as a camera flash or external strobe, to illuminate the subject being photographed. This technique is commonly used in various photography settings, including product photography, portrait photography, and event photography. The purpose of flash photography is to provide additional light when natural lighting is insufficient or when a photographer wants to control and enhance the lighting conditions. By using flash, photographers can achieve well-exposed and sharp images, freeze motion, and add creative lighting effects to their photos. Understanding how to use flash effectively is essential for capturing high-quality photographs in different shooting environments.
