I really doubt that Fuji shut it down without first doing the math. Frankly, the fact that they are shutting it down now when they probably have another few years of film in stock, is shocking. You would think that they would have done it far sooner. If they can’t sell enough to keep the factory open, it closes or gets repurposed. In the case of a place making film, I imagine that the regulatory headache and legal liability that comes with dealing with nasty chemical and the disposal of waste is reason enough, if all the other mundane costs of any facility wasn’t. Chemical photographs are a niche nostalgia market that dies a little more each year as equipment wears out and people who know what a negative is die.
Just ponder the costs for a few seconds. If they have a single engineer supporting the entire line, two technicians keeping all the equipment running, and a dozen operators operating the equipment and packaging it, you have already dumped a half a million in for personal, and this is all before raw chemicals, electricity, and the support staff to take care of those workers. Assuming these people could make film out of thin air by waving their hands, you would still need sell over 50,000 canisters at $9 a pop just to pay for the people to make the stuff.
Seriously, it is a minor miracle that Fuji made this stuff for as long as they did.
