All kinds of things are going to be chucked and trashed. We just don't know which yet. Film will probably be around just as long as any of the specifically current digital options. To continue to make money any mfg has to have something expendable, and if it isn't film, it's going to be the
electronics or associated software itself. Most pros have figured this out by now, and not all of them
can afford to rebuy every few years, so the long term prognosis for pro film looks pretty good as long
as it generates a sufficient scale of film base mfg. But this differs from format to format. A really
complicated problem which is very difficult to predict one way or the other at the moment. Why not
just buy whatever Portra you can afford and freeze it?
