Inside a forgotten kingdom: Incredible unseen images of China, Cambodia and Thailand in the 19th century go on show for the first time
These historic images of the Far East captured by Scottish photographer John Thomson will be exhibited in London for the first time this month.
The incredible negatives were taken during 1862 and 1872 when Thomson set off to Asia for the first time. Throughout his 10-year expedition, he recorded daily lives of east Asian people, as well as the royals and became the first photographer who documented Angkor Wat, the world's largest religious monument found.
The Scottish photographer and writer was able to capture the individuality and humanity of the diverse people of Asia, whether royalty or street vendor.
In 1862, Thomson travelled to Singapore where he opened his first photographic studio and became a professional photographer.
He used the method of wet collodion process, where an exposure was made onto a glass negative with highly flammable liquids. This had to be done in complete darkness, on location, in a portable darkroom tent.
