Agreed, US pros tended to favour US products more. That's why US processing of Kodachrome lasted longest - but it ceased to be cost-effective even there. What YOU must understand is that it is a complex, expensive and environmentally-unfriendly process that needs fairly high throughput to be profitable. There is no way on earth that that level of throughput can be managed even in the US, and that's assuming the process isn't banned for environmental reasons. The truth, the simple truth, is that there is not, and will not be, sufficient demand for Kodachrome to be profitable for any company; I'm absolutely astonished that you can't see that.2. It is important to remember the film market had regional variations AND still does. E-6 may have made great inroads here although you might be surprised at what film a lot of the pros favoured. American pros were a little different. Actually that is a huge understatement. American pros were very different!
