The world HAS changed. it's the denial of that reality among some (often very bitter) filmophiles that is part of the problem. They are stuck in a 1987 time warp. The nostalgia about how film may come back vs. digital is ludicrous. It's like saying we'll use the internet but with typewriters. Or if we all spend $4,000 on hard copy encyclopedias we'll bring back that industry.
I couldn't comment on bringing back encyclopedias, as I don't know very much about these. I was deprived as a child and the closest I ever got to a volume of Britannica was the occasional visit to my cousin's house.
Bug I digress...
It would be foolish and yes, perhaps even 'evangelical' to argue the longevity of film, as a going concern, on the basis of its aesthetic merits or historic (mass) appeal. Still, there are tale-telling signs even in the new, digital paradigm, confirming the existence of continued and even renewed interest in the medium, even if on a smaller (or vastly different) scale.
Film is an 'organic' medium for capturing likeness. It exudes true, 'continuous tone', which in some inexplicable way seems to 'connect' with the viewer. And while the same 'connection' can be made with virtually any medium, none lend itself to this task with comparable ease.
And so, there has been, in recent years, a growing trend to recreate some of the characteristics of film in the digital sphere. The most pronounced (and monetized) of these has been DxO's FilmPack 3.1 - a now-third generation *digital* product whose sole raison d'etre is to re-create the grain and exposure scale of various emulsions.
Does this save the industry? No, hardly.
*BUT* it does show that film can-and-does occupy a formidable place in <gasp!> even the digital workflow! And while entirely irrelevant to the question of its continuity as a viable business product or its continued availability, it shows that film will always remain at the significant core of any serious creative rendering process. The question of whether the artist 'reaches' the point at which film once again becomes relevant is exclusively in function of the individual's dedication to creating images and the depths to which they are willing to make this a personal obsession. Thankfully, artists can always be counted on to obsess!
I've posted some videos below for those of us yet unfamiliar with DxO Filmpack 3.
