There is a point where the friction of a medium stops being a productive challenge and just becomes a drag. That’s color film on 4x5. When you factor in the sheer cost per sheet, the dwindling number of labs willing to touch large-format E-6 or C-41, and the absolute headache of keeping a massive piece of plastic free of dust on a scanner bed, the math stops working. It kills the momentum. With 135 and 120, you can actually drop the rolls off, let the lab handle the heavy lifting, and keep moving. Roll film gives you the room to shoot, to observe, and to finish a thought without every click of the shutter feeling like a major financial and logistical calculation.
