In normal activities, I'm big on empirical data. In photography, I get away from that.
I don' t have a densitometer or do comparisons. I don't make plots or test charts. I've got film that I like and that works for me, and I think it will be useful and more expensive in the event of supply problems. I take film out of the freezer as needed and use it for making photos that I mostly enjoy.
I haven't seen the news that John Sexton is stockpiling it, but if he is, that's very telling. He's likely the last person to worry about the cost as he's effectively PR for Kodak and I imagine Kodak takes care of him. If he's stockpiling it, it's because he likes it and fears changes from Kodak's uncertain future.
