Film can't come back and be the main player in photography because there is a much higher profit margin in making digital cameras assuring that the camera makers new product will be digital.
However, because of the huge number of good to really good to great film bodies which are already owned or can be had a great prices, people who want good photos or even just the panache of shooting some kind of SLR and don't want to or can't pay the huge upfront cost of a DSLR are shooting away with film.
There is also the nostalgic aspect where younger people who didn't grow up where film was the only option feel a connection with the "old" days by using film.
That is what I'm interested in doing soon. I'd like to make Daguerrotype at some point.ALso, i find this interesting that more and more people are doing wet plate and tintype , who would have thought that would happen.
I think what has changed is the workflow. Film+scanning can lead to some really awesome and rewarding results. There are also instances where film's dynamic range makes more sense. The challenge now is finding a decent lab.
