Being an hour long each, that 3-part video was a little painful to watch. I had to watch it at 2x speed and it still took 90 minutes. But it was time well-spent.
Prior to seeing the series I had no idea how much effort it took just to manufacture the clear Estar backing material that Kodak uses for all of their film. I also had no idea that the Rochester, NY facility cost over a billion dollars to build, or that Kodak custom-manufactured films to third party specifications and ships ginormous rolls of custom-order film in huge "caskets". Even though photographic film usage has fallen off sharply with the advent of digital, Kodak is still in business manufacturing large volumes of film products for other purposes.
The section on custom-batch mixing of chemicals speaks to the online speculation that FujiColor 200 is just rebranded KodaColor Gold 200. Kodak has the ability to customize the chemical composition of every batch of film that they produce, which means that the similar sensitivity curves on the Kosmofoto site doesn't permit one to conclude that every other property in the two emulsions is the same. Even if Kodak is running batch productions of color print film for Fuji, it doesn't mean that they're letting Fuji sell the trade secret formula for KodaColor 200 in Fuji film boxes. People like to oversimplify things, which doesn't always lead to valid conclusions.
But it was time well-spent.
