Seattle FilmWorks is now known as PhotoWorks. They no longer offer deliver ECN films; their house brand is ordinary C-41 (made by Ferrania, the last I knew). It looks like they're discontinuing their film processing, as of March 13; it seems they're going digital-only.
I actually tried sending a roll to Ultracolor 100 to them last fall, and was VERY disappointed with the results. I don't know if I just got a bad batch, or if this is what is to be expected of the process. But given the results I saw AND the relatively high cost of the process, I would HIGHLY recommend just using slide film if you want slides.

Kodak Vision Color Print Film 2383 and its higher saturation version, Kodak Premier Color Print Film 2393, are still a possibility for printing 35mm color negatives into slides. From the data sheet (http://motion.kodak.com/motion/uploa...ab_h12383t.pdf), the contrast looks to be a bit higher than color print papers, but that may be fine for projection. These newer print films do not have a rem jet backing, so they should be easier to process. But the standard processing is different from either C-41 or RA-4, although the formulas are available on the web. Short ends may be available.
The contrast of commercial films and professional films is about 0.6 - 0.63 and the papers and now discontinued print films had contrasts of 2.5 to mach with these films. The paper has a Dmax of about 2.2 while the film had a dmax of about 4.0 just like the motion picture print films. This is due to the respective supports, paper and film.
Motion picture film is built to a contrast of about 0.50 and to achieve a print of the same contrast, the contrast of the print material must be about 3.0 or higher.
You can artificially alter these parameters by scanning and manipulation, but if you do direct printing, you will probably not like the results.
Thanks for the responses. Having shot slides pretty much exclusively for a number of years now, I find the experience of looking at prints or scans from negatives to be a big let-down. I was hoping to find a way to turn some of my better old negatives into slides. It doesn't look like this is feasible. :-(

And yet, I do this all the time!
before I had an enlarger...I used my macro extender rings and photographed a few negatives with normal B&W film, probably Tri-x, to make simple slides
the original negative didn't fill the frame, but the resulting "slide" wasn't too bad...nuthin' amazing, but at least I could see what the shots looked like & it was fun
Kodak still makes Duraclear a clear base positive display film. It processes in RA4 at twice the print time. It is a cousin of Duratrans display film. Mounting slides on this material would be inconvienient but not impossible and the resulting slides may or may not reproduce correctly if printed themselves. For display they should be fine.
The process requires a color printing darkroom.
Dwayne's will turn a neg into a slide for $1.10 a slide. Here is the order form http://dwaynesphoto.com/common/Slide...der%20Form.pdf

what is the difference between a reversal process and a negative process ?

a single step duplicating film that allows you to dup negative to negative or positive to positive
(sorry black and white only ) . it is the same that used to be sold by kodak as so-132.
i have used both the kodak version and the photowarehouse version ...
it is a safelight film, and very slow like azo - it requires a 300watt bulb to expose it,
and then the film is processed in print developer. ( film to film contact print )
i imagine it is the film that was used
on tv and the movies when they show people developing negatives with a safelight on ..
