A fascinating photo project is taking place over on Flickr. Jason Powell, who calls himself a cameraist rather than a photographer, takes pictures of present day scenes while holding up a photo of that exact spot from a moment in the location's past history. It takes your eyes a few seconds to process the two different scenes taking place. Most of the photos come from the Library of Congress and the ones chosen for the project tend to highlight buildings around the DC area (with some reaches into Virginia and Maryland). The biggest difference is how few cars are in the foreground of the black and white pictures.
