Adams helped found Group f/64, an association of photographers advocating "pure" photography that favored sharp focus and the use of the full tonal range of a photograph. With Fred Archer, he developed an exacting system of image-making called the Zone System, which described a method of achieving a desired final print through a deeply technical understanding of how tonal range is recorded and developed in exposure, negative development, and printing. The resulting clarity and depth of such images characterized his photography. Adams was a life-long advocate for environmental conservation, and his photographic practice was deeply entwined with this advocacy. At age 12, he was given his first camera during his first visit to Yosemite National Park. He developed his early photographic work as a member of the Sierra Club. He was later contracted with the U.S. Department of the Interior to make photographs of U.S. National Parks. For his work and his persistent advocacy, which helped expand the National Park system, he was awarded the Presidential Medal of Freedom in 1980.
If there were no copyright laws, you would not be able to protect your music after releasing it. People could take parts, or even your entire song and claim it as their own, and you would have no legal bounds or actions against the plagiarism of your work.
Street art would last because of the way people enjoy that others would take the time and patience of creating these amazing drawing and only doing it with a couple of cans of spray paint.
