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:

At left is perhaps the main attraction of this view, one of the grittier sections of Washington, not usually captured in period photographs. 8x10 inch glass negative, Harris & Ewing Collection.
