TTL, or “through the lens metering”, is a method that is used by modern DSLR cameras to control both onboard and external flash units and create a correct exposure. It uses a pre-flash to allow the camera to meter the scene, then generates the main or exposure flash to actually expose the image. The pre-flash happens so fast, that its invisible to both photographer and subject, but it is what determines the exposure.
