So I want to show you a quick experiment here since we've looked at what it's like to manually meter this out and find a flash exposure. Let's see what the camera would do if we left it to its own devices to make its own decisions. I have a Canon EO 60D here running a Canon flash system using their ETTL, might even be ETTL2 system. So this is their particular TTL automatic flash. I'm set in aperture priority mode at F4 and when I take the shot it automatically calculates based on a bunch of different parameters what it thinks the correct flash level should be and it gives me this.
