In these days of instant digital images, it’s hard for many to imagine the effort that went into creating photos during photography’s first century and a half. Each single image was precious.
To see full story: Photography’s era of glass plate negatives
Two types of glass plate negatives exist: the collodion wet plate, in use from the 1850s, and the silver gelatin dry plate, in use from the 1870s. Both processes are still in use by fine art photographers. Dry plates were commonplace for news photography through the early 1930s.
The Associated Press photo library, located in New York City, currently houses around 4,000 of these fragile dry plate glass negatives in its collection, most date between 1929-1934.
Here’s a look at some of the images scanned from those negatives.
Governor A. Harry Moore of New Jersey is shown with State Trooper James A. McBride near the home of Col. Charles A. Lindbergh at Hopewell, New Jersey, March 3, 1932, when the governor paid a visit to Lindbergh. The trooper is pointing out the points of interest in the infamous kidnapping case of the aviator’s 20-month-old son, who was tragically found dead.
