I visited the Centre for Contemporary Photography on the weekend to see the Lost and Found Project which came out of the Japanese Tsunami.

A million salvaged photographs had been collected that has washed up after the tsunami, the exhibition had displayed them as a large collage covering a whole wall of the gallery. The emotion evoked  was very moving and fascinating. A truly beautiful exhibition. Follow the link if you want to discover more. Posters of the exhibition are available online donations accepted to assist the volunteer project.  http://lostandfound311.jp/en/
