ELI5: How are some photos from 50+ years ago amazing quality?

Saw a few pictures from around the WW2 era and the quality/resolution is on par with some top of the range cameras today.

Good photographers + good-quality film = good photos, basically. 

However, there's also always the possibility the photos were tinkered with in Photoshop before being published in whatever magazine/web site you saw them on.
