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:
Washington, D.C., circa 1935. "Interior of D.G.S. Store, 3300 Connecticut Avenue, Cathedral Mansions." An interesting look at some Birdseye Packing Co. "Frosted Foods." View full size. 8x10 safety negative, National Photo Co. Note that by 1935, National Photo has made the jump from glass to film as a recording medium. Resulting in a more modern, contrastier look but a little less detail.
