Photoshop c.1911.
Altering photographs is not a new process only made possible through computers. Photographers have long had ways of altering their images to show what they wanted to show.
This postcard (LM76.13.105) shows the “breaking” of the Bayless Dam at Austin, PA. Obviously, the photographer could not possibly be standing at the base of the dam as it broke. This image was most likely achieved by scrapping portions of the emulsion away from the glass plate negative to create the white space, simulating the effect of rushing waters.
