Let me preface this post by stating I was 25 years in the c41 lab business and a former technician for Noritsu America corp (minilab equipment). I'm buying bulk old stock of MP film and spooling that into 35mm cassettes and saving a ton of money (like getting 24exp for .09 cents a roll). Remjet removal with baking soda & water is easy-peasy
So far I have gotten quite good results cross processing in a Unicolor C41 kit. This kit most likely has stabilizing agents as you can store the mixed solution for a year or so using it intermittantly to dev film as needed.
A friend of mine put out the theory that if they look that good in the wrong chemistry, imagine how nice they would look in the right chemicals. Hmmmmm. I have zero experience with ECN-II
I can mix up ECN-II from formulary/bulk chems but was curious on 2 things:
1. How many rolls might I expect from a liter mix?
2. How long will the solution keep once mixed?
With C41 chems I would want to consume mixed replenisher within a week or 2. If home brewed ECN-II has a tight leash before it turns into tarry pond scum I'm thinking I'll have to shoot film, let it accumulate, mix up a batch and use it on the accumulated film so the one questions remains --how many rolls out of a liter before it's exhausted?
