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.
Shared by JimEichholz: My great uncle Paul Salk (kneeling 2nd from left) together with the rest of his bomber crew in front of their B-17. He was a tail-gunner. Later he moved to a B-29, and unfortunately died in a rendezvous accident with another B-29. Photo was taken in early 40s. View full size.
