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.
If you ask me, one of these people is enjoying this ride more than the other. UPDATE: Well, as SilentEchoes57 has pointed out, this isn't the Giant Dipper. As the Wild Mouse had been gone for several years when I took this shot, this is probably the Jet Star, a smaller coaster ride that operated until 1991. 35mm Kodacolor 100 negative.
