C41: Portra 160 VC seems to come closest to the late, lamented Pro 100T which to me was the most phenomenal color print film ever made. Why does Kodak always discontinue things when they finally get everything right?
E6: Kodak EPY 6018, aka Ektachrome 64T. The king of kings. Responds beautifully to zone system control, has a contrast scale as long as Tri-X and perfect, I mean PERFECT color balance.
With this winter we've been having I smell a glorious Springtime a' comin'. You guys have reminded me that I need to begin stocking up on color film.
