95 years on

Years ago I had a book containing milestones from the history of photography. Included in it was Henri Lartigue's 1913 image of a racing car, speeding past the camera. The shutter action moved vertically from top to bottom, and as it did so transferred the light
onto the plate. With the pace of the car, the time which the shutter slit took to scan the lens became significant, such that circular
wheels were captured as ovals. So, I believe, the inspiration for Roadrunner's leg action was born.

Now idly snapping from the train to Sheffield, I find that by turning my iPhone to landscape format I can reproduce the same effect. We've clearly come a long way in 95 years.
