I havent heard anything as disastarous as the complete shutdown of the film making end of it, but there are signs that film is definately on the decline. Polaroid has ceased film making operations. They were popular with the large format crowd. Kodak has ceased the readyload lineup. Fuji tried to end the 50 ISO Velvia but it's back.
Locally, my film developping shop has quit the sale of film. They used to sell to pros, and they would sell the stuff by the case. 120 film at that. But the pros quit buying it, so he quit buying it as well. Now, I have bought some of their last stuff, and it was expired.
Film companies are in the business to make money, thats not a big suprise. But if the pros arent buying film by the case (my lab said they had more than a few clients that bought more than 200 rolls of 120 film a month) then they arent going to make a very big profit. Or if they do make a profit, it wont be a very fast return. It costs money to houseand ship film as it cant be stored in hot areas. All of these costs add up. So now if the pros dont buy it by the pallet, then its less profittable to make it. The less profittable it is, the more likely that more and more manufacturers will pull out of the film making business.
Kodak has more interests than just film. They sell cameras. But their biggest base is casual consumers. They dont make any SLRs anymore and the cameras they do make are for casual shooters more than anything. Small enough to carry in your pocket, yet enough quality to print a 4x6 if you crop the image a bit. Not terrible cameras mind you, just not something that most pros would pick up and use.
Same thing with polaroid. They make digital cameras. And the sales for the polaroid film has dropped significantly due to digital giving an equally quick (if not faster) result without the horrible cost of the film.
Now some companies may decide to fill the niche of the artists. There are many who will argue that film is still a better format than the top of the line digital cameras. And in the right hands they are right. But there needs to be more sales of the film for it to remain profittable for the companies to produce the stuff.
Buy a few rolls and support the companies that your uncertain will continue to produce it. Its about the only thing we can do. If film does go away then you will have to bight the bullet and go digital. Or you can make your own, but I dont know enough about that and it would be a different question.
