This thread has replayed itself over and over, like a vinyl record with a crack in it. Nothing is going wrong - tik - going wrong - tik - going wrong - tik - forever and ever and ever.
GET IT CLEAR! Film is a high tech item, but vinyl and oil paints are low tech in comparison. The best films we can make at home today compare with the era of Edison and 78 rpm! The best comparison with tubes (valves) might be a crystal set or old one tube radio.
So, if film vanishes, we will be able to make plates and sheet film, 120 roll film and papers in the speed of about 3 - 100 for film and up to current enlarging speeds for paper. Our sizes will run about 11x14 max with a yield of about 80% or so. With advanced equipment, we can equal the work of Jim Browning.
