Very plausible writing, but couldn't it simply be that Newman, in particular, simply had a well-developed sense of style and visual balance that he simply employed automatically as he saw fit? I sure did in my own past work, just as I still do today in play.
Writing about an extant image is an endeavour of unlimited possibilities which can be as long as the writer's patience permits. In my opinion, as well as experience, previsualizing, procrastinating and sweating before any job, jobs/shoots being the entirety of all that those photographic commissions were, is one sure way to freeze. Those guys never appear to have frozen. I believe they simply winged it, as we all tended to do pre-digital, unless trying to create an iconic self-myth.
Just a thought.
