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.

About 2.5 miles north of site of Kennedy Center.

[There's more than one Observatory Hill in Washington. The site at 2300 E Street NW (#14 on this map), about a thousand feet from the Kennedy Center, is where the old naval observatory was. Not the current one where the VP lives. - Dave]
