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.
The Edw. Neumann grocery at Broadway Market in Detroit circa 1910. 8x10 glass plate negative, Detroit Publishing. View superjumbo full size. (Which is still less than half the pixel dimensions of the full-resolution, 6100 x 5000 image -- i.e., less than a quarter of the available detail!) Who'll be the first to count all the cans?
