A dedicated flash is a portable flash unit designed to work seamlessly with a specific camera system, allowing it to communicate directly with the camera's electronics. When attached, the flash can be automatically controlled by the camera's exposure settings and programmed modes, enabling features such as TTL (Through-The-Lens) metering, automatic power adjustment, and synchronisation. Dedicated flash units help photographers achieve accurate, consistent lighting with minimal manual adjustment, making them ideal for portrait, event, and low-light photography.
