How Watkins saved Yosemite ?
Charleton E Watkins was an early landscape photographer in the US. He visited the Californian area in 1861 with his middle format film camera. He took high resolution images on huge slides.
The pictures somehow found Abraham Lincoln the president of the United States at that time, who liked the pictures so much that he gave the area a protection by law. Later the Yosemite became the second National Park in the US in 1890.
This was the first case when photography changed the history according to Matthew Butson the Vice president the Archives of Getty images.
