This is a series of images showing a horse walking. The photographs are arranged in two rows, each capturing a different moment in the horse's walking motion. The top row shows the horse from the side profile, walking from left to right against a gridded background. The bottom row shows similar photographs of the horse from behind, highlighting the sway of its tail and the alignment of its legs. The sequence conveys motion and is likely part of a study on animal locomotion, focusing on the horse's stride and physiology.
