I think Kodak just didn´t see the digital revolution comming. When they realized that sales won´t stop dropping they allready faced bankruptcy and no longer had the money to reasonable downsize production, or to make volume more adjustable.
Fuji on contrary went into pharmaceutics before the digital revolution, whether they seen it comming or not, when the dig. rev. hit they had enough money to reasonable downsize production, but they just didn´t do it. I get what Berkeley Mike is saying about investment, but by reasonable downsizing production Fuji would have kept a source of income. Yes, not a big one, but they would have kept one. Their cine films for example weren´t as fine grained as Kodaks Vision line, but they were at a competitive price and they had a different look - another choice for cinematographers which is nice to have.
But it seems like Fuji decided some time ago to drop analog. Let it taper off until "demand is too low", too low for their production volumes, and then close the door and scrap the machines. I even read somewhere that they scraped master rolls of Velvia in 2014, i think, though there were quite some interested in buying those, but nope Fuji is done with analog it seems.
So Kodak would like to move on but had/has serious problems, while Fuji could move on but doesn´t seem to want to.
I find it hard to see that Kodak did not see digital coming, at the end of the day they were the ones who invented the product that killed their own business.
I remember seeing kodak digital cameras on the market for a long time, but they were never popular and I remember most people buying the likes of Canon, Fuji, sony and Nikon for example.
Even Kodak's film cameras were very budget and low end consumer level for a very long time, just a piece of plastic.
It seemed to me they were not interested in marketing professional photographic equipment, but rather the film itself that the professionals used.
I think Fuji led the way in consumer digital for some time and was a major player of digital cameras, now with smartphones we are seeing a decline of pocket cameras also, so i think Fuji will be feeling the heat on this also, they certainly would not survive if they sold only digital cameras, but they do at least offer some real professional end cameras.
Now we see Kodak introducing a rather professional modern super8 camera which is good to see, I think if they can offer some new analog film cameras of reasonable quality to attract young shooters of film and an easy mail order processing service for all E6 films and I think their market will improve.
If Fuji ever pull the plug on all film or even Velvia alone, I think it would cause more outrage than it did for Kodachrome or Ektachrome combined.
Not that I am a fan of Disneychrome, but it is a very unique film. Looks like there is a strong base of shooters out there for Velvia.
