Perhaps it's worth noting that Kodak now provides "curved field"
projection lenses as standard for normal (cardboard, presumably)
mounted slides in their Carousel projectors, but their older "flat
field" design is recommended for glass mounted transparencies. The
current plastic mounts allow the film to "float" in part to minimize
popping, so there is less bowing. The differences are easy to see in
projection, and also frustrating since my college's slide library
intermixes all three types of mounts.
