Do tears of joy look the same as ones of woe—or ones from chopping onions? In “The Topography of Tears,” the Los Angeles-based photographer Rose-Lynn Fisher explores the physical terrain of one hundred tears emitted during a range of emotional states and physical reactions. Using a Zeiss microscope with an attached digital camera, she captures the composition of tears enclosed in glass slides, magnified between 10x and 40x. “There are many factors that determine the look of each tear image, including the viscosity of the tear, the chemistry of the weeper, the settings of the microscope, and the way I process the images afterwards,” she says.
