Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.
This is my first attempt to colorize an old photo (Times Square, photographed by John Vachon in 1943). I researched some of the signs in their original colors so I could be as close as possible in the photo. Such is the case with the "Saludos Amigos" poster and the Schaefer beer sign. View full size.
