Kodak better had laid a sound base for home film processing of transparencies which is a black and white film on a colourless base. Eastman-Kodak discontinued such stocks in 1957. 60 years ago!
Grey-base Plus-X reversal, Tri-X reversal, 4-X reversal, they were/are no joy to use. Now that Kodachrome and Ektachrome are gone they don’t know what to do, this is a trial-and-error game. The new Super 8 camera doesn’t have single-frame exposure, no tap for a cable release, and no footage indication when it’s off electrical power. Since Ektachrome goes with the relatively simple E-6 process it was only logical for blind Rochester to make that step.
They could, in fact they can, make a good black and white reversal film (with AHU) and sell it cheap. Films are too expensive. If you want to increase sales of a product competing with many other products, uniqueness alone won’t do. Analog renaissance based on the crappiest camera ever? No chance. They’d better aim at the thousands of often quite old but reliable cameras around, flood the market with their yellow boxes containing what’s so much needed. Film makes for ten percent of Kodak’s business. It could be much more through a film such as reversible Super-XX. In every format. 10"×8", 7"×5", 5"×4", 70mm, 220, 120, 35mm bulk, 135, 126, 16mm bulk, 110, Double-Eight, Double Super 8, Super-8. And talk about projection!
