I've been trying to take more long walks, on which I usually carry a camera, or two. A lot of what I see to shoot is architecture, so I've wanted to carry a large format camera around, and while I can easily throw a tripod over my shoulder and carry the Speed Graphic or Horseman in hand, I haven't found a good way to carry the film. In cool weather I wear cargo pants with two holders per side, but they feel a little awkward. Has anyone found a better solution, short of wearing a backpack? I'm thinking about something like a surplus cartridge belt, but I'm not sure what size would fit the various holders (2x3 and 4x5).
