And I'm posting this here rather than in the filmies' forum, because there may be those who never look in there ... Yes, Ektachrome existed as a Kodak brand name before, and had several variants over time, but I'm not clear what relationship the new film has to any of the old stock - I assume that the chemistry is similar, though it is to be made on different production lines on a smaller scale to suit modern demand, hence the current trials. Nor do I know what iso rating(s) the new stock will be. I'd guess that 100 is likely? What's pretty certain is that it will behave as slide films always did, in that it will have a small exposure latitude. Slide films are a good training ground for judging light and setting exposure because of their lack of leeway - you HAVE to get it right in camera, or you're f00ked. And this might work against any new-age experimenteers (sic) who've romanticised about having a go with it and who've never used slide film before - it'll call you to book. But there IS romance in film. Its roots stretch way back into the history of photography. And despite some impracticalities it has a certain texture that digital can never properly fake (though that texture varies according to the size of the film original). Here's to diversity ... a celebration.
