Best known for his dramatic and evocative landscapes, Ansel Adams is considered one of the most influential photographers in US history. He produced beautiful images of American nature – from high mountains and thick forests, to the rugged ocean shoreline.
To celebrate his pioneering work, the National Maritime Museum at Greenwich in London has brought together more than 100 of his most powerful pictures.

These days we are used to presenting landscape images in colour but these photos display the power of monochrome landscapes.
