Subjects are generally at similar distances and placements. If you stick a subject on the edge of the frame, it isn't going to work very well in TTL. Whether you have to cut back on the light depends on the film used and the desired look. I use slide film in TTL less a stop in both the ambient and flash. The main subject gets a double dose of light and stands out nicely from a slightly subdued background. Different effects and films will require different settings. If you are just opening up the eyes a little with print film then I wouldn't knock back the ambient at all. TTL flash is very helpful but it does not replace the need to think and plan.
