Flash In photography, a flash is a device used to produce a brief burst of bright light to illuminate a scene or subject. It is commonly used in low-light conditions or when additional light is needed to properly expose an image. Flash units can be built into the camera body or attached externally, and they can be operated manually or automatically to synchronize with the camera's shutter.
The light emitted by a flash helps freeze motion, reduce blur, and enhance image sharpness, especially in indoor or nighttime photography. Flash photography requires careful consideration of factors such as flash power, direction, diffusion, and color temperature to achieve optimal lighting effects and avoid harsh shadows or overexposure. |
