I actually don’t use any expired film unless its just old film of mine that I found and forgot to use. I like the uncontrolled factor to be as contained as possible, which using lomo cameras is pretty high with just the camera, so adding the random effect of expired film feels like too much. So, long story short, I do shoot Kodak Portra 400 and Ilfored 3200, but all fresh. I love the color of the Kodak and I love the texture of the Ilford 3200.
