This is a test comparison between normal ECN film processing and bleach bypass (aka "skip-bleach). This was NOT done digitally in post.
I shot identical scenes on two rolls of Kodak 7219 500T film and then processed one normally and the other with a skip bleach.
Overall, the skip bleach tends to desaturate colors, but primarily in the blues and greens. Skip bleaching increases contrast especially in the mid tones. Skip-bleach processing also tends to favor UNDER exposing by 1 stop because it seems to push the highlights.
