Before and After Restoration - Alexander Gardner's Stereograph - "Antietam, Md. Confederate Dead in a Ditch..."
3D red/cyan anaglyph created from glass plate stereograph at Library of Congress - Prints & Photographs Online Catalog: www.loc.gov/pictures/
LOC Title: Antietam, Md. Confederate dead in a ditch on the right wing used as a rifle pit
Date: Sept. 19, 1862
Photographer: Alexander Gardner (1821-1882)
Link to glass plate: www.loc.gov/pictures/item/2018666241/
Notes: I started restoration work on this stereograph two years ago. The glass plate negatives at the Library of Congress are in bad shape and apparently have been so since their creation, based on Civil War era prints that I've seen. Both the left and right sides are plastered with black and white spots and blotches, and both are missing large sections of the emulsion, which can be seen by alternating the closing of your left and right eyes, while wearing your red cyan 3D glasses. My working photoshop file has about a thousand layers and adjustment levels, in an attempt to restore some clarity and retrieve the lost 3D due to the missing sections. See my two previous flickr postings for information about what is pictured here.
