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:
Oil City, Pennsylvania, September 10, 1875. At 6 a.m., one of the receiving tanks was struck by lightning.
Glass lantern slide, about 3.5 x 4 inches.
I found this same image on a stereo card published by Frank Robbins of Oil City. Does this mean that Frank Robbins also took the photo, and that this was his glass slide? I have no clue.
Also, blown up to its full 55M glory, this is just an especially beautiful picture. The tones and textures are fantastic. View full size.
