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.

Left half of glass-plate stereograph, from photographs of the Federal Navy and seaborne expeditions against the Atlantic Coast of the Confederacy, 1863-1865. View full size. Note the unusually elaborate sign, as well as what seem to be the giant wheels of an artillery carriage.
