Accessory shoe is a plastic or metal mount on the top of a camera designed to hold various photographic accessories such as external viewfinders, rangefinders, or flash guns. Also commonly referred to as a "hot shoe" when it provides an electrical connection to trigger a flash, the accessory shoe allows photographers to expand their camera's functionality and improve lighting, framing, and composition options. Proper use of the accessory shoe is essential for studio photography, event shooting, and advanced creative techniques, enabling photographers to attach and use compatible equipment safely and efficiently.
