Faces are but a gallery of pictures. Bill II (1991), a block portrait by Chuck Close, reduced to one-third of its actual size and cropped. Compare its appearance from near and far (>5 m) or compare it with the tiny copy of Bill II (see inset). Ignore the pupils, nostrils, and the line between the lips, which have much higher resolution than the 1.3-cm grid that represents the rest of the face. Below each letter in the eye chart is a number indicating its size (the observer's acuity) as a fraction of a mark (a filled square of the painting's grid). (Oil on canvas, 92.4 x 76.2 cm. Photograph by Bill Jacobson.)
