Kodachrome processed as Ektachrome

[winbert]

At http://8mmforum.film-tech.com/ (more for film collector not film shooter), someone says that Kodachrome K40 can be processed as Ektachrome.

Is that true?

and what will be the result?

secondly, why K40's processing cost for B/W is so expensive. Is there different chemical or lab just want to take advantage?

thanks

In color? No way! Martin Baumgarten can process it as reversal B/W or sepia tone....

If you run Kodachrome through any Ektachrome process (ME-4,EM-26,VNF-1,E-6), The result will be blank film. This is because the bleach removes the silver image, and since there are no couplers in the film, the dyes do not form on the film.

As for the price to process Kodachrome as B&W, the issue is twofold. First, most of the people that need this service have old films that require special handling. Sometimes this means doing clip tests, adjusting temperatures, and mixing up special chemicals. Another reason is the rem-jet backing, which requires each roll of film to be hand-cleaned either before or after processing. If someone could modify an ECN-2 machine to do B&W, it would go a lot faster. However, the economics are just not there.
