A lost collection of hundreds of previously unreleased color photos of American troops in the months before D-Day has recently become available. Here are the uniforms worn on D-Day and the subsequent campaign in France, but photographed under ideal conditions, by skilled cameramen who could control the lighting and re-shoot to get every detail right. All of the major units stationed in Britain before D-Day are covered, with many details visible that are often obscured in photos taken on active operations.
