A carved timber lattice screen covers a window opening

A lone tree casts a shadow on a wheat field on a hot summers day

A detail of the golden and inlay robe worn by the Reclining Buddha

A blazing red sun saturated with dust kisses the horizon above the savannah plain at sunset

Painted rocks surround a makeshift garden bed in an arctic village adding colour to the street scene

A canopy of colorful prayer flags flutter on a Himalayan mountain

Antarctic base staff eating a meal behind a kitchen wall in a blizzard on the sea ice during a survival course

The silhouette of a chestnut Bhotia Pony grazing in a high altitude wetland floodplain on a cold morning

Liquid nitrogen is loaded into a vacuum flask for transportation

A palm tree silhouette against darkening tropical storm clouds

Scorched earth and smoke after fire burns tropical open woodland

The skeletal outline of a huge tree stark against a tropical blue sky
