Stumbled onto awesome photo albums by Andrew Gray. He lives in Japan, and organizes regular volunteer excursions to a Cambodian village and orphanage. Thought I would share the links since Cambodia is in the top two of Kiva recipient countries, must be some enthusiasts here!
He is trying to raise awareness of their needs though his blog. I suppose these people are mostly too poor for microloans, though, so their safety net is donations.
Anyway I was moved by his documentary-quality pictures of beautiful people!
