I have been developing my c-41 in Kodak Flexicolor LU at 37.8 degrees C for 3:15 in a jobo cpp2 with great results. I was recently asked to push process some AGFA Vista 2 stops for a friend, and I'm wondering how long to extend the development?
I am so proud that no one 'naysayed' this act of treachery. Yes, sometimes C-41 film can stand a good push. Honestly, there won't be 'crossover', but with contrasty images, there might be reduced shadow detail (along with more brilliant midtones). - David Lyga
