Change is a series by German photographer Ralf Graebner, of very large, extremely detailed photographs depicting the metamorphosis of American quarters he found on the streets of New York City. For him, these coins are precious artifacts that captured time, conveying a facet of our history. He is fascinated by their metamorphosis, from looking identical when minted to becoming unique, wildly differing objects when he found them. Using a technique similar to computerized tomography scans, each final image is composed out of thousands of thin image slices, resulting in prints with unfamiliar visual richness, presence, and three-dimensionality.
