The most famous of the photographs is attributed to David Bachrach, who was positioned in front of the speaker’s platform. Discovered in the 1950s by Josephine Cobb, an archivist at the National Archives, it remains the only undisputed image of Lincoln at Gettysburg — seemingly taking his seat on the platform hatless, his head bowed.

The photographers may have missed Lincoln’s speech, but sometimes they inadvertently captured one another, providing clues to their exact position. During a preview of his research, Oakley pulled up one of Gardner’s shots, zooming in on a window in the Evergreen gatehouse to point out a blurred figure and a box: the photographer Peter Weaver with his camera, he said.

Oakley’s research had its snarls, starting with the Bachrach photo. “That one took me three years to figure out,” he said.

For one thing, when he lined up the tops of people’s heads in his 3-D rendering, their feet were buried ankle-deep in the ground. Then, last month, he found a National Park Service report confirming that in 1934, the ground had been regraded, raising it about eight inches.
