Process EM-25 - What is it?

[htmlguru4242]

I got a Super8 camera today, and it has a film cartrige in in. The cartrige is labeled "3M Color Movie, ISO 40, Process EM-25".

I have never heard of this process (didn't even know that 3M made film ...)

I'm assuming that it's one of the "E" processes, though I don't really know. Does anybody have any info.?

It is probably a 3M E3 or E4 workalike process.

3M once made lots of film here in Rochester and at their plant in Minnesota. They also bought Ferrania and got much material from them, particulary color.

Ok, I thought so. It is good to know that it's something at least standard (though old).

I have NO IDEA as to the workings of either E-3 or E-4; is it possible to process this manually (either with the correct chems. or perhaps in a modified E-6 / C-41 process)? I'm not necessarily looking for quality; I just want to get some images off of this.

Ideas anyone?

No, the E3 and E4 films were very low in hardness. They required 75 deg F processing or a prehardener and use at 85 deg F. The VNF process on the Kodak web site has the formulations of the solutions and the process sequence of what I suspect to be the correct process. Just a guess.

Did a little search for you on the net so take the qoute for what it is, this is what one person had to say.

Process EM-25 was the final process for non-prehardened movie
films, and an interim process, just before EM-26 came out. It was only
made for a short time period, and it more similar to the E-6 process
colorwise, but the film still had to be run thru Pre-Hardner and then
Neutralizer and a rinse, prior to being in development.

Rocky Mountain Film processes old film and has an explaination of EM-25

The formulas for the E-3 and E-4 processes were given in the Dignan Newsletter. The Newsletter is available on microfiche through major libraries.

I'm not so sure about VNF - although Kodak have now discontinued all chemicals and film material on environmental grounds.

I know somone who would offer an opinion - Ludwig Draser who runs Andec Filmtechnik in Berlin. They are a professional motion picture lab and could probably process it - if it is worth it.

If you want to get this film processed, I recommend you get in touch with Martin Baumgarten in Plattsburgh, New York. His email is Super8mm@[spambots are everywhere]aol.com Remove the obvious addition. He also has a site on AOL that describes the prices for the services he offers. He is the BEST for scratchless, high-quality film processing. I forget the URL, but if you were to do a search for "Plattsburgh Photographic Services" the link would pop up. Hope this helps.

Thanks for the suggestions; if I need film that's odd processed well, I'll DEFINETELY look these people up.

I probably didn't make it clear (my fault), that I don't need this proffessiopnally processed; it's film form the 1970s - 1980s ish with about 10 feet of somebody's home movies + some stuff that I've shot around home just for testing. I'm really looking for a way to process it myself (preferably in color). Does anyone have any ideas on MANUALLY processing it?

Dschneller - where did you find that info on the process? - it seems useful ...

 

[dschneller]

It's from the same gentleman that FilmIs4Ever suggested. He posted the information on usenet in Dead Link Removed, his website is:http://members.aol.com/Super8mm/Super8mm.html. He also
recommends visiting KODAK's New Super 8 dedicated site

Email Martin Baumgarten. Tell him you want to process it yourself, and I'm sure he has a copy of the instructions lying around somewhere. He walked me through processing black and white reversal in a morse rewind tank.
