Using bulk EDUPE 5044 as direct slide film

I have run across some KODAK 61.5MMX100 ECHRM EDUPE 5044 that from all I can find out is a 100 ft roll of 25 ASA E-6 slide duplicating film conveniently the same size as 120 film.

I have found a few references that it's a low contrast film without high saturation, but I'm not sure I completely understand all the implications of that fact.

Obviously it is *POSSIBLE* to hack this up into pieces and tape it to some of the scads of backing paper I have cluttering up the place, but is it likely to be worth my trouble? I've seen more than one mention that exposure is tricky, but I think that was about trying to use it properly to duplicate other transparencies, not using a meter and exposing for 25 ASA in a camera body.

Does the "low contrast, normal saturation" description imply that it's something like Porta in chrome?

Has anybody done this? Does it work OK, or you can already tell me not to waste my time?

Thanks,
MB

not bad - ideas here

I too have old dupe film, but in my case, its 35mm.

The trick is that even with daylight, is likely to need some filtration on exposure to balance it to give straight colors.

The idea of low contrast is right. I have not tried this, but a thought is to see what happens when you extend the color developer step in the e-6 processing ( this presumes you are hand processing e-6, which may not be applicable to your situation.

The other option is to apply a hybrid workflow, and see what can be made of the images after some post scan processing. That would be a better discussion to have on the sister - hybridphoto - site.

At least what you have is 61.5mm. I have rerolled 120 rolls with salvaged spools and backing paper fed with a (new to me at the right price) 70mm bulk roll of 160 portra c-41, and while the process works, it is a pain in the *** to work in the absolute dark wrestling the film onto the rolls while wearing cotton gloves to keep the film clear of fingerprints.

Another aspect is that all colour-copy films are spectrally sensitized to match their subject which are the dyes of the film to be copied. Typically they ommit the overlapping of the response curves of the three sensitizers as seen in camera films, and show a gap around 600nm.

Thanks for the tip that it may need filtration. I do suppose one could fix it after scanning, but I don't normally scan. I had hoped to just have some E-6 that I could shoot in high contrast situations that would give me a little more muted response.

The re-rolling part isn't all that appealing, either. I can do it, and I've unspooled 120 and respooled it to 620 a lot of times for my parents old cameras from when we were kids just to be able to drag them out at family events and amuse everyone. (Nobody can believe that a Bakelite camera from 1950 still works and takes great pictures. Of course, I've got far better emulsions to choose from, and I have total control of the darkroom.)

I've also cut down 120 and spooled it on to 127, which is a lot of trouble sitting in the dark with sharp objects. (But at least I still have all my fingers and toes.)

It's beginning to sound like this isn't all that great an idea. Really it sounds like a lot of work and questionable results for not all that much cost savings unless my time is pretty worthless. After all, the hours in the darkroom spooling film are hours not spent shooting pictures.

For me the 100' of 70mm portra 160nc came for $35, and the task of slitting it and winding it down to 120 rerolls can work when the spool can yield about 30 plus re-rolls, and the new individual rolls of this stuff bought locally cost me over $7. each

If you send the film to Film For Classics they can load it onto 120 spools for you. I have a 36 exp. roll of EDUPE which I want to try for direct shooting too. I think it has a nominal speed of 12. If the wind stays really calm and the sun is out I might get some nice leaves with it.

Good Morning, Michael,

I haven't used E-Dupe, but I have used the earlier Kodak E-6 copy film, Ektachrome Type 6121 (4 x 5 size) as a camera film. I used it as a film for night photos because of its inherent low-contrast characteristics. In long-exposure nighttime situations, the color balance problem is reduced because, at least in cityscapes and similar situations, a somewhat less-than-real color becomes more or less acceptable. I used the double-exposure method (a few seconds while there is still some daylight left just after sunset, then several minutes after compete darkness). I found the results, with a deep-blue sky, very acceptable.

Konical

Hmm- maybe it would be easier to re-roll as a 220 roll? You could definetly maximize your time that way. The hard part would be getting the length and backing paper attachment right.
