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.

Allan Pinkerton ("E.J. Allen") of the Secret Service on horseback. Antietam, Maryland, main eastern theater of the war, September-October 1862. Glass negative (wet collodion). View full size. Photograph by Alexander Gardner.
Not inverted. There is writing in both top corners (not reversed) and along the bottom (reversed). You will also see "7468" written on the grass in the foreground to the right. This is a glass plate negative, and can be marked on either side. Writing that looks black is done by scratching on the emulsion side (or with white paint). Writing that looks white was done with black ink.
An-teet-am (with emphasis on 'teet')
For years I as a European have asked myself how to pronounce Antietam. Can anybody tell me?
