Mr Baker Brown came across these three Sherpa children at 3,800m above sea level. "I just indicated with my hands that they should get into a group and they did the rest."

To capture Everest at sunset, Mr Baker Brown used a red filter to accentuate the colours and give the mountain a fiery quality. He learnt to use his digital camera by trial and error.

Another of Mr Baker Brown's experiments, this time with a blue filter. "When you're in the mountains there seems to be a blueness in the clouds and I intentionally made it more blue."

"I saw this lovely-looking young child in a monastery in Kathmandu," said Mr Baker Brown. "It seems to capture what I feel about Buddhism - peace, serenity and gentleness."

One of a number of portraits of Buddhist monks. This one was sitting in the street in Kathmandu waiting for passers-by to provide him with his day's food.

Mr Baker Brown is a West Ham fan, but asked his guide, Nuru, to show support for his local team in Dorset. His next trip will be to Everest's north face later this year.
