Hi guys - hope someone can help me. I'm new to film and have just run my first roll through a Minolta X300 using Kodak Ultramax. I'm seeing a weird effect that I don't understand. Each image on the roll seems to have a greenish cast on the left hand side and a magenta cast on the right hand side (which also looks underexposed, though maybe that's the cast?). Is this a camera fault, faulty film or developing fault? I'm attaching two scans here from the developing lab, but I can see it on the negatives as well, so it's not the scanning.
