Flashes refer to brief bursts of light or energy that occur suddenly and intensely. In photography, flashes are used to illuminate subjects or scenes in low-light conditions, capturing clear and well-exposed images. They can be either built-in or external accessories that attach to a camera, providing additional light when needed. Flashes are essential for professional photographers and hobbyists alike to enhance the quality of their photos by eliminating shadows, reducing red-eye, and creating a more balanced composition. Whether used in studio settings or outdoor environments, flashes play a crucial role in achieving stunning visual effects and ensuring optimal image clarity.
