The owner said they are doing over a thousand rolls per day. At $9/ roll, that's over $2 million in revenue. Sure some of that will go to keep the lights on, chemicals, employees, and good ole taxes, but it's still a good business.
Film is keeping Kodak alive. Kodak had film sales of $2 billion in 2007, which was about 20% of total sales. However, they made a profit of $369 million off film sales. Conversely, sales of digital cameras were $4.6 billion (about 45% of total sales), but they lost $92 million.
The equipment to make Kodachrome is long bought and paid for. So whatever they sell, is at a much higher margin. All of this is good news for Kodachrome. I see it being around for several more years.
