What is the material that was used on older bellows? My linhof cameras came with a shiny black polished bellows that looked like leather from the outside, but was reinforced with a mesh or fabric inside. Was this a sandwich of fabric and thin leather or of a kind of fibre paper? It smells like leather too or maybe this is the smell of the varnish. The replacement bellows are now made of matte synthetic material. They are not as decorative but they do the job quite well and are maybe less sensible to moisture. Any comment on the different type of materials used for bellows? Thanks!
