The default Third Person is Third Person Singular; you see the story out of one set of eyes. The usual variation is given as between deep and shallow immersion; the difference between describing what is seen and done as if it were seen on film, and describing all the interior life and thoughts as well.
But there’s a distinction I haven’t seen made. I’m gonna call it Clinical versus As-Experienced. The “As-Experieced” version of third-person deep immersion is, “Karl realized he was enjoying shooting the men streaming from the burning building.” The “Clinical” is the one that can go on, “Karl was acting out of a deep-seated nihilism he had yet to fully recognize.”
Anyhow. As far as I am concerned they can technically do the same things, just with a change in pronoun.
