Born 26 May 1895, Dorothea Lange made a mark for herself in American photography through a 1930s New Deal program that sent her around the country documenting the United States during the great depression. You may know her most recognized work, Migrant Mother:

Happy Birthday, Dorothea! Thanks for the iconic photography, never forgetting what your subjects longed to be and always capturing their dignity.

The County Archives in Sogn og Fjordane works to preserve the heritage of their Norwegian community. We celebrate their entry into The Commons with a sprinkling of lush photographs from some of their many collections.

You’ll love the lovely lantern slides of the fjords of Norway: The collection consists of slides produced by at least two British photographers – professional photographer Samuel J. Beckett and amateur photographer P. Heywood Hadfield. Other fun sets include Leisure, Portraits and the portfolio of Andreas Mathias Anderssen.

The Commons exists to show you hidden treasures in the world’s public photography archives and how your input and knowledge can help make these collections even richer. You’re invited to help describe the photographs you discover here, either by adding tags or leaving comments.

Photographer Eric Fischer is doing some pretty darn cool data visualization in his set, The Geotaggers’ World Atlas. Using geo-tagging tools, his imagination and some fancy Perl scripts, Eric is plotting Flickr photos on a map and highlighting 50 major cities in a vector view. Shown above are New York, San Francisco and Hong Kong. The different colors represent different modes of transportation: Black is walking (less than 7mph), Red is bicycling or equivalent speed (less than 19mph), Blue is motor vehicles on normal roads (less than 43mph); Green is freeways or rapid transit. Lines never looked so cool.
