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.
Vintage photos of:
"St. John's Church, 16th & H streets N.W." From a series of dozens of National Photo glass negatives showing various Washington landmarks. The Library of Congress has given them a date range of "between 1918 and 1920," though they all seem to be from around 1900. Anyone out there from the LOC? View full size.
