I was following orangutans in Borneo with my wife, Cheryl Knott, a primatologist who has spent 30 years working in Gunung Palung national park, in the Indonesian part of Borneo. I am a biologist by background, and did my PhD research in rainforest ecology in Borneo, before I went into photography and film-making. I saw so much destruction in the rainforest back in the 90s, and it dawned on me that I could publish scientific articles that maybe 10 people would read – or an article in National Geographic that 10 million people would see.
I was getting increasingly serious about my photography while working on my PhD when I got funding from the National Geographic Society for field research. Through that connection, I was able to show them my pictures and eventually I published an article in the magazine about my work, which in turn meant I was able to get an assignment to document Cheryl’s orangutan PhD.
