Duplicating 6x6 slides

How might I go about duplicating 6x6 slides? I can't find edupe in 120 film. Does contact printing work? Any advice?

Contacting under a colour enlarger works fine but there is always the problem of dust and scratches on the glass. I used to do a lot of duping commercialy 20 years ago, and we would use the enlarger set at 1:1 magnification with a 150mm and then project onto 5x4 duping film. It will never be as sharp as contacting but in most instances will be absolutely fine. Making sure the film is masked, it is possible to get two 120 dupes on a sheet of 5x4. The only near 120 film I think was 70mm but doubt that is available. Not sure if any dupe film is still around actually. Shame no one wants dupes any more. Used to be good money in it!

The kodak publication lists that you can buy 120 size edupe. I can't find it though...

Can you use a film like sensia or provia to duplicate film? Wouldn't the contrast be high?

What would be a baseline for exposure? How do I measure the kodak standard of 1 footcandle?

Blimey, dupe film is still available. http://www.kodak.com/global/en/professional/products/films/edupe/edupe.jhtml?id=0.2.26.14.21&lc=en

I would imagine most shops would have to order it in from Kodak. Don't worry about footcandles, just do a test strip with a good range of stops. As I remember, and it was a long time ago, a De Vere 504 enlarger with colour head set as my previous post was around 1-2 seconds though can't remember what the lens was set to, probably f16. The film will have a recommended filtration but tests will then have to be made with normaly just cyan and magenta, (or was it yellow?), to work out a more accurate filtration. Would imagine normal E6 film will be too contrasty. Make sure the original transparency is upside down in the enlarger, so when projected on to the dupe film it will be the right way around when the processed film is viewed. Though if contacting, best to do it emulsion to emulsion. And remember..... more exposure makes it lighter and less, darker.

I found your post searching for information about it myself. It's available from Unique Photo here:

I'm still trying to figure out if it is what I want, but if it's want you want there it is.

in the dramatic pause I found a box of fuji 4x5 dupe film a year out of date on ebay for $38

A little judicious flashing will lower the contrast; The Bowens duper has that function built-in.
