Indigenous Neth from Cambodia has been a research collaborator and interlocutor of Swiss anthropologist Esther for more than fifteen years. He has also worked with other anthropologists and filmmakers as a cultural and language translator, field assistant and research collaborator.

In the years since his community was evicted by rubber companies, he has given countless interviews to journalists, NGO workers and anthropologists. Some victories have been achieved, the communities' struggle for indigenous land and livelihoods well documented, but the fight for the land continues.

Neth had begun filming and photographing while working closely with three filmmakers but was too busy pursuing this career himself because of his activism. The Yellowstone trip was a good opportunity to take up photography again.

As it turned out, on this field trip to the greater Yellowstone area, Neth and Esther switched sides.

Neth carried out participant observation among the anthropologists. He recorded with the camera what he thought was remarkable.

A keen observer of everything going on around him, Neth captured the habits of anthropologists at work: How they conduct participant observation, blend in and do what tourists do, record, film, photograph, listen to experts, take notes, discuss their insights and draw preliminary conclusions.

It was only afterwards, when Esther was sorting through the pictures that Neth had taken with her camera, that she realized that he had been studying the anthropologists at work.

Neth achieved what every gifted participant observer wishes for: his observations went unnoticed by those he was observing.
