I previously had a rudimentary understanding of log, but the author's other recent piece devoted to it in the context of the iPhone 15 pro (https://prolost.com/blog/applelog) gave me a much better appreciation of its importance to professional-looking video. From that article:

> But with this iPhone 15 Pro Max footage shot in Apple Log, I can recover all the detail — or just let it overexpose gracefully into this ACES output transform, for a smooth, film-like look. This soft highlight rolloff in the log-to-video conversion is called a “shoulder” in film, describing the upper part of the classic s-curve. A nice shoulder for your highlights is a big part of what makes footage look “pro” — especially when your grading happens underneath it.
