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.
I've seen some colorized pictures here but have never tried one myself. When I saw this picture I thought I'd make an attempt, to see if I could give a feel for what it must have been like to be there. I didn't base my color choices on any actual reference, just what looked OK. It didn't come out as well as I'd have liked, but it's still interesting. View full size.
