A lot of Pollyanna's in this thread. A lot of conflating arguments as well. Yes, film will be around for a long, long time. In the world of niches. So use it. Just like oil paints and carburators. Just like copper plate and glass plate; still around. Yes, more people are using film right now but the industry is a shell of its former self and this won't change. I imagine sales of b&w film has remained relatively steady for the last few years because it has been a niche for a long time- I have no numbers to back this up though.
The argument that Freestyle or B&H is out of a film shows high demand falls flat on its face because films were available everywhere not long a go. Sure, it's the internet and everyone shops online but I can still get shoelaces at Amazon or at the shop down the road ; film not so much. And like someone mentioned there is no longer convenient infrastructure to get the most out of your film. Most film now is digitized anyway, which is what; better than nothing? Hardly a good business model.
Celebrate roll and sheet film, but it will celebrated as a niche product. Not quite sure why this threatens people.
