Thanks for the link. I'm going to show that to my photography students this afternoon. Most of them want to do video (not my strong point, but the music teacher, who is co-teaching with me, it's his area ).
Haven't been able to watch the clip yet but 1922 is pretty early for Kodachrome. Godowsky and Mannes didn't even start working in Rochester until 1929-1930. Interestingly they were musicians and they timed the development timing processes to the second by playing the final movement of Brahm's C minor symphony in the dark. Those two are very important individuals in giving us the world of color.
Very cool. Sadly, I think our day and age will later on be remembered, as a cluster of all sorts of useless nonsense unlike beginning of the past century.
"Kodachrome... You give us those nice bright colors You give us the greens of summers Makes you think all the world's a sunny day, oh yeah! I got a Nikon camera I love to take a photograph So Mama, don't take my Kodachrome away"
