Ansel Easton Adams (February 20, 1902 – April 22, 1984) was a landscape photographer and environmentalist known for his black-and-white images of the American West. He helped found Group f/64, an association of photographers advocating "pure" photography which favored sharp focus and the use of the full tonal range of a photograph. He and Fred Archer developed an exacting system of image-making called the Zone System, 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.

I have often thought that if photography were difficult in the true sense of the term -- meaning that the creation of a simple photograph would entail as much time and effort as the production of a good watercolor or etching -- there would be a vast improvement in total output. The sheer ease with which we can produce a superficial image often leads to creative disaster.
Your equipment DOES NOT affect the quality of your image. The less time and effort you spend worrying about your equipment the more time and effort you can spend creating great images. The right equipment just makes it easier, faster or more convenient for you to get the results you need.
