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.
At the request of tterrace and with his help, I'm going to start uploading some pictures that a family friend has let me borrow for scanning purposes. The negatives range from 2 1/2 X 4 inches to 2 1/4 X 3 1/4. The trunk these negatives were found in was sealed in 1964 and was only recently opened. They belonged to the friend's uncle who was a land surveyor in San Diego. That's as much as I know.
This picture was probably taken in the early '50s. View full size
