Toronto. Using an old 1913 Graflex camera. My friend and fellow PHSC fan Russ Forfar sent me this link about using an old Graflex which had only two working speeds – slow and slower – to shoot high speed F1 races.
The photographer used a century old film based reflex beast while all others used modern digital cameras. 10 film holders allow for at most 20 shots per event. The lens appears to be back of the lens board in the shot that shows the camera front.
Have a look at his work and think back to the need for serious thought and planning when you only had a few shots in the camera.
