No matter how cliché it may sound, it seems that photography sometimes really can change the world and influence the course of history. A perfect example of this is a 19-century American photographer Carleton Watkins.
He was born in 1829 in New York, and upon moving to California, Yosemite became his most favorite subject. Believe it or not, it was thanks to his work and his love for Yosemite that this area was preserved. And not only that – he also influenced the development of the national park system in general. This is the story of photography that, indeed, changed the world.
