“However, pre WWII Germany had the world’s finest photographic industry,”
They were on the cutting edge of audio recording as well. They pioneered magnetic tape.
The thing that surprised me about Leni Reifenstahl’s two epic movies, “Triumph of the Will” and “Olympia,” is that, even though she had Hitler’s total, enthusiastic support, she didn’t make them in color. IMHO color just makes all the difference and comes a lot closer to showing how things were.
