Photographs from the era can be a bit of a rabbit hole.
This very muh related to how they were printed on an enlarger. "Dodging" and "burning" while on the enlarger were pretty common to get the desired print out of the exposed film.
The film stock the image was printed upon mattered, especially for when it was scanned digitally.
It was really hard to get "safety" shots (going up or down an exposure, or shutter speed) while taking "action" shots. So, the photographer often tried for the middle, and knew they could try and salavage the shot on the enlarger when actually printing the photo.
And not one of those schmos gave one thought to the people, 75 years later who would pour over those photos picking out details. Those meanies.
