Christopher Bonanos write for the Washington Post: What Kodak could still learn from Polaroid. He goes on to explain the mistakes of Polaroid and what Kodak should learn from that to survive and keep film coming. The key argument is right here:
Yes, the remaining buyers of film are weighing this technology against digital methods of image-making. But theyâ€™re not choosing film for reasons of economy; it could never compete. They are choosing it for a particular look and feel, and because they want to differentiate themselves. Some are old-school professionals who prefer to work in familiar ways.
Bonanos is the author of Instant: The Story of Polaroid that I recommend.
