Smil’in Cambodia is a book of photographs which captures local people smiling. There are several categories such as Hat, Golden Teeth, Young smile, Krama, Faces, Monks & Wats, Working Class and Barang as well. Greg's hope with this book is that the viewer will both see, and hear, the great joy of the Cambodian people. The pictures were captured throughout the Kingdom, from Phnom Penh to Mondulkiri, Siem Reap to Kratie and Kampong Cham to Battambang.

Based in Phnom Penh, Greg Mo is best known for his intricate and colorful photographs of unexpected and mysterious moments.
