About the Photos

Our holdings include hundreds of glass and film negatives/transparencies that we've scanned ourselves; in addition, many other photos on this site were extracted from reference images (high-resolution tiffs) in the Library of Congress research archive. (To query the database click here.) They are adjusted, restored and reworked by your webmaster in accordance with his aesthetic sensibilities before being downsized and turned into the jpegs you see here. All of these images (including "derivative works") are protected by copyright laws of the United States and other jurisdictions and may not be sold, reproduced or otherwise used for commercial purposes without permission.

A Fast Horse: 1914

A Fast Horse: 1914

Washington, D.C., 1914. "Wrisley Brown, attorney, riding." You'll note the Washington Monument showing a decided tilt to the left, although the reason is more optical than political. Harris & Ewing glass negative. View full size.

Heels down, Wrisley!

Elbows in!

Amazing Timing!

Obviously, in 1914, stop-action photography was a long way off; yet somehow, the photographer managed to get this shot of the horse with all four of his hooves off the ground at the same time.

[Eadweard Muybridge first accomplished this 36 years earlier in 1878. -tterrace]

Thank You! tterrace - I stand corrected. The old adage about learning something new every day just hit me in the head like a V8 commercial.

Focal Plane Shutter distortion

It appears that the photographer was panning the camera to follow the horse and rider and the focal plane shutter effect caused the trees and monument to appear to be leaning.

Examining the image further I think I see some additional focal plane distortion in addition to the monument and trees...

It appears to me that the horse looks like it not as long as a regular horse and the rider appears to be too big for the horse. Maybe it is just my eyes playing optical tricks on me.

Vertically Moving Focal Plane Shutter

The photographer panned the camera.

This is a single curtain focal plane shutter which uses a long black cloth with horizontal slits of different width pre-cut. It runs vertically close to the negative between two sets of rollers. It is spring driven and winding up the spring motor also rolls the shutter curtain back to the feed roller.

When the shutter is released the slit travels in front of the film. The faster the "shutter speed", the narrower the selected slit is because the shutter curtain travels at the same speed (inches per second or some other measurement) for a range of shutter speeds so that "shutter speed" ends up being the amount of time any given part of the negative is exposed to light. If I have this right, the slit was traveling top-to-bottom relative to the photographer. The negative image is being projected upside down inside the camera so it is "seeing" the light start at the bottom of the image and moving up.

In the old racing car photos you might see slanted oval tires (camera relatively motionless) or slanted posts and poles in the background (camera panning).
