Flash refers to the brief burst of bright light emitted by a device, typically a camera or smartphone, to illuminate a subject during photography or videography. It is commonly used in low-light conditions or when additional lighting is needed to enhance the visibility of the subject.
The importance of flash cannot be overstated, as it plays a crucial role in capturing well-lit and visually appealing images. By providing an additional source of light, flash helps reduce camera shake, eliminates motion blur, and improves the overall quality of the photograph. Furthermore, flash can be employed creatively to achieve specific lighting effects, such as fill-in flash to reduce harsh shadows or backlighting to create dramatic silhouettes.
