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.

1865. "Charleston, South Carolina. Ruins of Roman Catholic Cathedral. View of doorway." Glass plate negative, left half of stereograph pair. View full size.
Let's just pretend I never made that comment!
It would be nice to see both pictures of the stereo pair side by side...even on a computer monitor, you can view the pictures in stereo without stereo glasses--you kind of have to cross your eyes to do it, but it can be done, and if it's a good picture with lots of depth, it's quite interesting.
[Now accepting donations for the Shorpy Stereo-Pair Extra Bandwidth Fund! Let's say $1200 a year. Anyone? Another issue is that two photos side by side would have to be small enough to fit on the average video display without scrolling, which means there is no detailed high-resolution image, which is what most people want to see. The alternative -- posting two sets of images, stereo pair plus one high-res -- would mean using up gobs of space on the server for something of limited interest. Plus of course it's twice as much work for yours truly. - Dave]
