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.

February 1942. Akron, Ohio. "Conversion. Beverage containers to aviation oxygen cylinders. Removal from solution tank at a rubber factory now producing metal essential for the Army. This bath, which follows the removal of the weld scale, gives the inside of the cylinder a further cleaning and removes all chemicals which may remain from the previous operation." 4x5 nitrate negative by Alfred Palmer for the Office of War Information.

The light that makes this shot is the one behind the man. See how it lights both the subject and the figure, both giving depth and mood. Brilliant. Staged though, obviously. Also look at the movement in the man's hands, you can see the rope through them.

There's a good chance that this photo was taken at the Firestone Steel Products Division in Akron. They also assembled Bofors wheel mounted cannons for the war.
