Final answer:
a. Eadweard Muybridge set up twelve cameras to record the first car as it drove by the number of cameras used by Muybridge was 12.
b. Eadweard Muybridge set up twelve cameras to record the first car as it drove by the purpose of Muybridge's setup was to study the motion of animals and humans.
c. Eadweard Muybridge set up twelve cameras to record the first car as it drove by the subject of Muybridge's recording was a horse.
Step-by-step explanation:
The photographer Eadweard Muybridge is well-known for his pioneering work in photographing motion. The number of cameras Muybridge used for his famous experiment was twelve, and the purpose was to capture the subject of his recording, which was a horse's motion. This investigation was significant as it resolved the question of whether a horse takes all four legs off the ground during a gallop.
In his experiment, the motion was recorded as a sequence of images that showed the horse, "Sallie Gardner", owned by Leland Stanford, running at a 1:40 gait over the Palo Alto track on 19th June 1878. The result was a ground-breaking series of photographs called The Horse in Motion, which also highlighted advances in photographic technology by demonstrating the capability of nearly instantaneous exposure.
