Dear Jan,
Possibly, but I still don't think so. Most serious photographers do their own B+W film developing, but slide is far more dependent on commercial E6 labs. It is the decline of these, rather than film availability, that has slaughtered slide film.
Dear Roger, it depends on the country:
For example here in Germany, which is one of the most important markets for slide film (in 2011 the slide film sales here have been
double the sales of BW film!), we don't have such a decline in E6 labs.
Dozens of professional labs are doing it, most of them nationwide via mail order.
And we have more than 3500 drugstore chain shops were you can get slide film and development. And the development is very cheap, between 1,95 and 2,55€.
In the Netherlands, Suisse, Austria, UK, Hong Kong and Japan for example there is also no lab problem.
Even in the weak US market, where the film infrastructure is much worse compared to Germany, UK or Japan, you have more than ten E6 labs offering the service via mail order.
So in the US you have only three main film online sellers (FS, B&H, Adorama), but more then ten places you can get your E6 films developed via mail order.
And mail order is mostly even cheaper than using your local lab, because you have fuel cost, parking ticket costs, bus costs and your time loss if you use a local lab.
And you always have the opportunity to develop at home. It is not very difficult to develop colour at home. Lots of steps are even more simple with colour than with BW.
And, to repeat what I said before, no-one denies the advantages of slide film, and not just in quality. You are of course right about colour refs (not that this always weighed heavily with repro houses); I have myself given illustrated talks with slides; I love the convenience of being able to pull out a page of slides from my filing cabinets and select the ones I want. It is just that in my opinion -- and presumably in Kodak's -- the commercial viability is (a) declining and (b) irreversible.
I've had a longer phone call with one of the biggest film distributors in Europe yesterday.
They told me Kodak Alaris is discussing to start E6 again.
The pressure from the European and Asian markets, and especially from Kodak UK, is very big, I was told.
And not only the pressure from photographers, but also from users of 8mm and 16mm film.
So for all the Ektachrome lovers: Send Emails to Kodak Alaris and tell them that you need Ektachrome back.
It may be a little chance, but there is a chance.
It is in our hands to keep E6 alive. If we use it, it will stay.
Cheers, Jan
