Late last week, controversial free stock photography website Unsplash announced that the Library of Congress, CDC, the New York Public Library and 10 other major institutions would be adding hundreds of scientific and historic images from their collection to the site's archive.
This week, the New York Public Library announced that it has released 187,000+ high-resolution digital images of public domain items in its collection.
It seems like every few weeks another long-lost photo archive is discovered and digitized, and the newest of these archives is a set of one thousand historical images taken as part of a Farm Security Administration project in the early 20th century. The photos -- some of which were taken by the likes of Dorothea Lange, Walker Evans and Russell Lee -- were originally put together to combat poverty, but have instead become an important glimpse into what was then simply everyday American life.
The New York Public Library has a massive collection of over 40,000 vintage stereographs (two photos taken from slightly different points of view). To properly share them with the world in 3D, the library has launched a new tool called the Stereogranimator. It lets you convert an old stereograph into either an animated 3D GIF (which uses "wiggle stereoscopy") or an anaglyph (the kind that requires special glasses).
