Muybridge. The Human and Animal Locomotion Photographs. 45th Ed.

Open this edition and the grid is the first thing that registers. Page after page of numbered frames, each a sliver of a movement caught and pinned in sequence, printed against the ruled backdrop Muybridge set up to measure exactly how far a body traveled between exposures. The 45th anniversary hardcover keeps the plates large and the reproduction clean, so the old collotype grids read as they were meant to, as measurement and as pictures at the same time. A nude figure descends a staircase across twelve frames; a horse gallops across sixteen. It is a spreadsheet that happens to be beautiful.

What does it actually mean to see a body one fraction of a second at a time? Before these plates, the question could not even be properly posed. The eye cannot freeze a gallop or a stumble, so painters guessed, and guessed wrong, giving horses the rocking-horse stance with all four legs splayed that no living horse has ever struck. In 1878, using a bank of trip-wired cameras strung along a track in California, Muybridge settled a wager and proved that a galloping horse does lift all four hooves at once, though only when they are gathered beneath its body, never when they are extended. The shutter had overruled perception.

The Pennsylvania work of the 1880s, Animal Locomotion, is where the project turns vast and strange. Thousands of sequences: men lifting, women pouring water, children crawling, a boxer swinging, an amputee climbing stairs, animals borrowed from the Philadelphia zoo, every subject shot from several angles by rows of cameras firing in series. This edition draws heavily on that archive and on the rare first album, The Attitudes of Animals in Motion, so the method visibly matures from one ingenious track-side trick into a systematic atlas of movement.

The apparatus behind it was its own feat of engineering. Batteries of twelve, twenty-four, sometimes dozens of cameras were wired to fire in precise succession, their shutters tripped by clockwork and electromagnets, freezing intervals far shorter than the eye can parse. The French physiologist Etienne-Jules Marey was chasing the same questions with different tools, and between them the two turned the study of movement into a science with a shutter for an instrument.

The life behind the plates is nearly as improbable as the pictures. The railroad baron Leland Stanford hired him to settle the horse question; a few years before that he had shot and killed his wife's lover and walked free, acquitted by a jury that ruled the killing justified. None of that turbulence reaches the frames, which stay as calm and methodical as an inventory. What this particular edition gets right is access: the original portfolios are museum holdings, priced like them, and gathering their essential plates into one affordable hardcover puts a founding body of work on a working shelf instead of behind glass.

The reproduction is faithful to the strangeness of the originals. Muybridge printed in collotype, a process that holds fine tonal detail, and the plates here keep the slightly ghosted, silvery quality of that method, along with the frame numbers and the measuring grid behind each subject. Nothing is cleaned up or modernized; the images arrive with their period texture intact.

It is impossible to study these grids without seeing cinema waiting inside them. Muybridge built the zoopraxiscope to spin the sequences back into motion, and the line from that spinning disc to the movie projector is short and direct. Every photographer who has thought in bursts, every sports shooter riding a motor drive, every animator breaking a walk cycle into keyframes is working in a language this man wrote. The medium that would define the next century was already implicit in a single stack of still frames.

There is a compositional lesson buried in the format as well. Laid out in a grid, a movement becomes a sequence of choices, and the eye learns to ask which frame in the run is the one worth keeping, the apex of the leap, the plant of the foot, the instant a gesture reads clearest. Every edit made on a contact sheet is a smaller version of the judgment these plates lay bare.

Some of the sequences are simply lovely, too, in ways their maker may not have intended: a woman turning with a fan, water arcing from a basin, a child's uncertain first steps broken into a dozen tender stills. The science was never obliged to be beautiful, and yet again and again it is.

What keeps the grids alive, past their history, is how much they still teach the eye. A run decomposes into the precise instant the trailing foot leaves the ground. A thrown punch reveals the counter-rotation of the hips a single frame would bury. Watch the sequences long enough and everyday motion stops looking continuous and starts looking assembled, built out of positions the mind ordinarily skips. The plates make the case that fluency in movement is something you acquire one frozen instant at a time.

Set it open beside the monitor before any shoot that turns on movement, a dancer at the top of a leap, a boxer, a child sprinting across a set. Study how Muybridge's runner truly distributes weight through a stride, then watch your own burst load in and count how many frames you were about to discard that hold the very position the plates taught you to want. The old grids still tell you when to press.
