Eadweard Muybridge was known for his discovery of stop motion animation. This means that in his early study of photography he was able to capture motion in single framed images. This means when they’re played at 40 or more frames per second it tricks our eyes and mind into it actually moving when it’s just rapidly changing photographs.
As you can see, the multiple pictures taken show us the process of movement that a horse will take to run. But this also showed how to make animations because without this study, there would be no animation like what we have today.
