ive tried to search for them, but nothing really has come up. Im sure people have experimented, interesting that it can be done in c41, but would be more difficult to do in ECN chemistry.
See here for instance, the thread contains links to other relevant material. I am quite puzzled by this Cinestill film: it is based on an ECN-2 film which yields lower contrast and needs a different development agent than regular C-41 films. In order to avoid the low contrast issue the maker rates this ISO 500 film as 800, hoping that push development would fix the contrast. Still, the C-41 process uses CD-4 as color developing agent whereas the ECN-2 process required CD-3. Photoengineer has already commented extensively on this issue.
Trying to be the best of whatever I am, even if what I am is no good.
