Just look at film workflow: labs are small. Either BW, C41 or E6. Itīs done by a few people in a smal place. There isnīt a big investment to have a photo lab.
Even if comercial labs shut for any reason, film can be developed by enthusiasts in their bathroom. Chemistry for mixing your own BW developers is available.
New films are coming from eastern europe. It doesnīt take much for a bunch of guys w/ an entrepeunerial attitude to look for companies in europe which could produce stock.
The so called film rennaissance happened outside of the big corporations marketing departments. It happened on the outskirts of industrial production. Social media blasted the news. Cameras were cheap on ebay. People need comercial opportunities outside the usual trap.
Digital looked cheap but when we found out 3k cameras were disposable trash in 5 yrs since their sensors were outdated, film looked like the real deal.
Not everybody wants to shoot bursts of frames. NOt everybody wants 12000 asa.
Mechanical machines have sweetnness electronics canīt give. Film, BW paper, have sweetness digital canīt give.
Itīs doable. Itīs here.
