Achieved this effect accidentally. I pulled out the roll out of the canister, and reeled it. I swapped with other film, an put this one in Jobo paper tank. And forgot about it in about a year. When I finally realized that there was a loose film in the tank and thought that it ruined already, I decided to experiment with it. When processing it, I agitated vigorously with inversion agitation. Prolonged the color developer time by 20 percents of normal time. Then resulted like so. Thanks for your comments.
