An interesting article on PDN about a new software to detect manipulations in digital photos.
Aim of Stipple is to “create an ecosystem for web images”. In (extra) short, it is about metadata that connect pictures with information about subjects and copyright.
A new, very interesting on line tool. I quote from the homepage:
www.camera-obscura.org is a digital library on the history photographic techniques. Several thousand books public domain will be available soon online for free with the possibility of advanced research directly in the book content.
