I'm with 2F/2F on that. In situation of high contrast like the one shown as example, when using slides or digital one has not to burn highlights and any kind of "averaging" is not guaranteed to place highlights not too low on the toe.
In this situation I would point the dome toward the light source, and that would be my first choice, letting the shadows fall where they may. I might also make a second picture (or second series) with +0,5EV which might put the highlights nearer the top toe but would open the shadows a bit more.
The high-contast final result of the example is likely unavoidable with slides (without light control, that is) but is probably avoidable with B&W film. We have to assume that the photographer deliberately chose the high-contrast effect he got. I suspect that with B&W one can make such a portrait while preserving details in the shadows, if so inclined.
