Americans first started experimenting with Louis Daguerre’s new photographic process around 1840, 50 years before Frederick Fargo Church snapped this picture of George Eastman with a Kodak camera on board the S.S. Gallia. The Terra Museum’s current exhibit American Photography: 1839-1900 looks at the development of photography over those years and, through the camera’s eye, documents the period–the Civil War, the Wild West, politicians like Abraham Lincoln and Andrew Jackson. The exhibit includes American daguerreotypes, made on silver-coated copper plates; rare samples of paper photography, which had replaced the daguerreotype by the mid-1860s; Edward Muybridge’s sequential split-second studies of animal locomotion; and photos taken in the 1880s with Eastman’s easy-to-use Kodak camera. The exhibit runs through July 8 at the museum, 666 N. Michigan; hours are noon to 8 Tuesday, 10 to 5 Wednesday through Saturday, and noon to 5 Sunday. Admission is $4, $2.50 for seniors, and $1 for students. Details at 664-3939.
