Hi have just watched a very interesting documentary on the life of Ansel Adams the great American landscape photographer on YouTube. https://www.youtube.com/watch?v=jvt1ImIKi0U .
I mention it in my blog as Adams’ work, Serra Nevada the John Muir Trail was pivotal in persuading Congress and President Roosevelt to in act a law to protect the wilderness of the Serra Nevada which became known as Kings Canyon National Park. It struck me that documentary photography can take on many unexpected forms and can sometimes make a difference.
