Photogrammetry
A photograph of a Photogrammetry machine scanning the Tightrope Artist, one of the miniature figurines from Calder’s Circus at Whitney Museum. On the left a pointed machine that resembles an oversize ballpoint pen tip and an affixed camera are pointed upward at a small burlap figurine balanced on two wire legs above a metal post. On the left side of the brown burlap is a vertical line of vivid violet light, presumably from the Photogrammetry machine.
