| Kodak was a film company, not a camera company.
What Kodak didn't realize, and its competitor, Fuji did realize, was that Kodak was actually a materials, coatings & chemical processing company, but it thought it was a photography company. As you recognize, the expertise wasn't in how film works, it's how film factories work, and the people who knew semiconductor factories made better sensors.
If they did realize this, they'd be around today making graphene or medical instruments.
And for a number of decades Kodak, along with Perkin-Elmer (also in upstate New York) made the most impressive photography system in the world, i.e. the film-based NRO surveillance satellites, and could never talk about it. That big stream of revenue also died.
