Process ECN-2 for Pictorial Use

Hey PE, you have been most informative on this thread.

You said that some processing plants might splice in smaller rolls into larger motion picture film runs. Do you know of any specific plants in the US that would do that?

No. Sorry. That factoid was passed on by a friend, but he gave me no names. And, that was a few years back. I have lost contact with him.

I apologize for the late reply. I don't get notifications from this site.

I believe it was my Kodak Pakon.

-13 in contrast on initial capture. Then I re-up the contrast/saturation a bit in Lightroom.

I also have a Fuji Frontier SP500 which also has good results.

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?

Resuscitating this old thread after acquiring 4,000 ft of Agfa XT100. It was $20. Processed in C41 it does produce what I think is a printable image, so film looks to be fresh enough.

I see it's still possible to buy CD3 fresh from Art Craft in 100g powder. Anyone know mixing instructions? Are the remainder of the steps and chemicals the same as C41?

This negative has a red base, unlike the orange base familiar to me having shot Cinestill and still films. My Epson 4990 scanner didn't seem to know how to correct for it, but I didn't try very hard. In RA4 darkroom, anyone tried to correct for the red base this simply with enlarger settings?

Kodak has published the ECN process formulas on-line.

Thanks, PE!

It took a lot of googling due to many broken links, but found it!

Processing KODAK Motion Picture Films, Module 7 Process ECN-2

All documents in that module: H-24 Processing Modules for Motion Picture Films

It's pretty cool that they publish their formulae so openly. I guess it makes sense that they make money selling film, so it's good for them to have customers not struggle.

Interesting they note that steps following stop bath can be done in room light. C41 process according to Z131 states lights can go on after bleach step.

I had always wondered about that too.

Because C41 doesn't have a stop bath and bleach functions as a stop bath too?

Pretty much correct, but in addition, the ECN stop is way more acid than your normal stop being Sulfuric Acid. This really removes the chemistry fast and drops the pH.

Some body will correct me but I think a US company used to load movie film up and then process it. I don't think they do it any more.

If they don't you might want to check for a shop that processes movie film. Hopefully they can do short bits of film.

With luck maybe one of the people with a movie background will see this.

The company was Seattle Film Works. They sent you a free roll of ECN film and you returned the exposed film to them. You paid them for color slides and prints. Along with the returned color slides, color prints and negatives they sent a new roll of film.

I have made prints from ECN negatives and as PE said the contrast is a bit less but not unpleasantly so.

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

Sent from Tap-a-talk

Why are you worried about ferricyanide? It is not poisonous except in the case of contact with strong acids.

I use the following method for the remjet coating. Eliminate the prebath to remove it, it is not needed. After development and stop bath I take the film off the reel and hang it up. Then with a clean sponge GENTLY remove the remjet. Make sure that none of the carbon particles get on the emulsion side. A final spray of water and then back on the reel for the rest of the processing.
