Process ECN-2 for Pictorial Use

Nzoomed · Dec 17, 2012

This is a rather interesting thread, as im interested to look at shooting this if E6 dies.
Can anyone here post a pic of a developed ECN2 negative?
I cant find any images of it anywhere, but am interested to see one, as i expect they look quite different without the orange mask on C41 films....

I know that this thread is probably dead, but just to clarify is there a fixing step required?

isshin · Mar 18, 2013

Nvm, just reread op.

newcan1 · Mar 18, 2013

Yes, there is a fixing step.

The title of this article is not well-chosen, as ECN-2 film is intended for pictorial use too.
The differences between motion ECN-2 film and still-C-41 film aside of processing chemicals have been laid out above.

Good article! Especially since I just found out that Kodak has discontinued ECN2 kit chemistry. :-(

There was a home kit!???

Where did you get that information about Kodak? It is still listed.

What they did discontinue are test strips. They are designated ECN-2 Uniformity Test Kit.

From the Kodak horses mouth...

I have an email from a Kodak rep. for North Carolina, and I quote:
"Dear Dino,

Thank you for your interest in Kodak and Kodak Motion Picture Film.
I am the Kodak Regional Account Manger for our Entertainment Imaging Division here in North Carolina.
Unfortunately we have discontinued the ECN Kit Chemistry due to low volume sales. I know that there were a few labs that I called on here in the Southeast that used these Kits but they have either closed or have moved back to bulk mixes.
Dino please call me If I may be of further assistance.

Respectfully,

Mike

Thank you for that update!
As said in their catalogue dated April 1st those kits are still listed. It should also not be overlooked that the developer kit e.g. contains concentrates to make 200 L. So, these are not "small" kits. And by that volume hardly useful for us Apuggers.

Well, the discontinuation of test strips makes sense in this context.

Anyway, ECN-2 kits are still made in Europe.

Since it was asked earlier, Kodak's CD-4 Color Developing Agent has the chemical name of 4-(N-ethyl-N-2-hydroxyethyl)-2-methylphenylenediamine sulfate, but a real easy way to exactly specify a chemical, even CD-4, is by the CAS number, which are unique numerical identifiers assigned by Chemical Abstracts Service to every chemical substance described in the open scientific literature.

For Kodak's CD-4, the CAS # is 25646-77-9

I'll have to dig through my notes regarding the other color developing agents.

Photo Engineer · Jul 6, 2014

That should read p-phenylenediamine sulfate IIRC. And CD6 is (N-ethyl-N-2-methoxy-ethyl), and CD3 is (N-ethyl-N-2-Sulfonamido-ethyl). They are all part of a series.

Film area processed per liter.

Does anyone know approximately how many rolls of 36 exposure 35mm film it is possible to develop with one liter of this formula? Thanks...

kb3lms · Jul 18, 2014

At least 8 because I have done it.

Is there an alternative to ferri-cyanide? Or a ready made bleach/blix chemical that one can obtain?

Try C41 chemistry. It will work after a fashion. It can leave silver metal and silver halide behind, but you will clear out the bulk of the image silver and get a usable image.

What about the remjet? I've been looking around for a reliable way to remove the remjet from the film.

No, but I want to not cross-process it. I want to go with ecn-2, without using not-so-healthy chemicals

I thought the examples were lacking in this thread, so here are some pics I have using this formula. Shot on Kodak Vision3 5219

mohmadanalog · Jun 30, 2015

This site sells those chemicals, and may speak to the company's sales manager and he told me that he has the ability to be doing a discount (large) to the members of the photographic community

What times and fixer is used

I anyone is paying attention to this anymore what fixer is used or does the bleach do it and what are the processing times?

analoguey · Aug 5, 2015

I have checked with local chemistry sellers(lab chems) and they don't have CD-3 or variants. So if I get the actual generic chemical that CD3 represents would that be okay?

Also is all this mixing supposed to be done outdoors? Or if indoors with max ventilation?

Thanks John! Those images look nice! What did you scan them on?

Photo Engineer · Aug 5, 2015

I would wear rubber gloves, eye protection and a lab apron. Ventilation is always good.

As for CD3, it comes as various salts. If you get the generic chemical you may have to adjust the weight you use if the salt is different. I know of 2 OTOMH, and they are the Sulfate salt made from using Sulfuric Acid, and the Tosyl salt made from using p-Toluene Sulfonic Acid.

Are you referring to the proper chem lab gloves made of thick rubber? Or can I get by with disposable nitrile gloves? (I use them for all developing/processing/printing right now)

Also, the generic chemical is what you mention below? Or is they're another name for it? (I'm assuming CD-3 in generic form is synthesized chemical that one can get in a packet)

I have not given the complete chemical name for CD3 here. That was a corrected name for part of the formula and did not include the acid portion. CD3 is synthesized and is usually sold in bulk or in small bottles depending on scale.

Have you considered using one of the processing plants used by Bollywood for their motion picture film. They would probably splice in your rolls and run them just as plants here in the US do.
