That's really beautiful, temp and time? 20°C and what was the dev time?
Another poster did CN17 (or NK17? Ya know agfa color neg...) in C-41 at 20° and for 20 minutes, but yours seems to be a better color cast and exposure, so wondering about your version. Thanks!
Yes, I have many alter egos around here posting under my name.
Ektacolor was developed for 20 minutes as well. Better color cast and exposure are just due the sheet being taken from factory-sealed package without much oxygen to ruin the film.
Those Agfacolors, which are btw _not_ C22 films, are just plain 120 rolls and 135 cassettes exposed to much more oxygen and moisture.
