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.

This takes place in a room entirely surrounded by copper screening in order to protect testing from any interference. This is the job requiring the highest skill. Even technical training, such as an electrical engineering course, must be supplemented by a course of training at the plant for this particular work." Photo by Lewis Hine. View full size.
