Few people have greater need for a holiday than David Yarrow. The veteran fund manager spends most days navigating the toughest investment waters in economic history. And when he takes a break, he really takes a break.

Over the last four years, he has flown to some of the most remote places in the world to photograph environments as far from the murky City streets as possible, as part of a project making his book Encounter.

In these photographs, he documents the scorched plains of Kenya, alongside the stunning Okavango in nearby Botswana and all the life that breathes within it. So impressive, that some of his photographs have been nominated for this year's Wildlife Photographer of the Year award.
