Four Corners

Four Corners allows a photographer to add context to their photographs and is a collaboration between Open Lab, the World Press Photo Foundation, based in Amsterdam, and the International Centre for Photography, New York.

Four Corners shows the reader before and after frames, the backstory, technical and copyright information and links to even more. All of this is accessed by rolling over or swiping through the four corners of the picture.

Readers and subjects can add their own perspectives and even attach audio and video content to the photograph using Four Corners Plus. This technology also gives the reader control over how they filter this new material, and can also see how the photograph has been altered from the photographer’s original – something which has enormous implications for improving trust and reliability within the media.

This ability to verify authenticity and provenance of photographs has never been possible but by using distributed ledger technologies (such as those that BitCoin is built on) researchers at Open Lab have, for the first time in the history of photography, found a way.
