Not stupid at all!

Ansel Adams and Jay Hannah, the painter, did extensive study. Hannah for
both Kodak and Poloroid.

Adams broke the gray tones into ten 'Zones.' and Hannah determined there
are 64 shades of gray in discernable gradations.

Does that tell why AA came up with the Zone system and his f64 theory? Yes!
In fact that's almost all of it, exactly.
