checking shutter sync a half century plus ago

getting things in sync …

Toronto. In the dying days of WW2, an article was printed in Popular Mechanics showing an impromptu way to ‘test’ a shutter – flash synchronization. The February, 1945 issue suggests photographing a flash bulb with caution and slow film to check the shutter sync for a particular camera/shutter/lens combination…

A clever idea by the look of it. The aricle surfaced through the diligent searches of my good friend, George Dunbar. George generously shared the article with me to pass it along. George and I were both kids back in 1945, but years later shutter (and lens)  testing was a big deal for serious amateurs. Testing the accuracy of my Exakta shutter brought to light its potential failure.

One of the brass shutter stops was almost cut off. Ironically, when I visited a friend back home (another George) who also had an Exakta of the same vintage, I learnt his shutter had actually failed and had had to be repaired by him as the ribbon on one curtain was broken in two.
