Content partnerships — Digital image restorations — Joint events

The Wikimedia movement has a growing pool of volunteer editors who will do high quality restorations of historic photographs, lithographs, etc. as a courtesy for institutions who release bulk material to Wikimedia under a free license. Examples of some of these restorations are below.

Examples

Altstadt (old city), Dresden. View from the War Ministry. This restoration was done in thanks to the University of Dresden library for their generous promise to donate a quarter million images directly to Wikimedia Commons. Left: Original version. Right: Restored version. Cropped, dirt and printer's mark removed, uneven ink application corrected, histogram adjusted and colors balanced. Selective denoising in sky. Featured picture on the English Wikipedia.
