Learn what is TTL flash, how to do TTL flash photography, and about TTL flash vs Manual flash.
TTL flash (through-the-lens flash) is used in photography exactly as the automatic mode of your camera. The main difference between the TTL flash and the Manual flash is that the TTL flash synchronizes with the camera in order to automatically detect the required flash output as per the nature of the subject and the frame.
