Photography is a visual art form that captures images using light-sensitive materials or digital sensors. Ansel Adams' "Moonrise, Hernandez, New Mexico" (1941) is a well-known example of black-and-white landscape photography. Understanding photography matters for making and analyzing art because it involves technical skills, aesthetic choices, and the ability to convey meaning through images.
Ansel Adams was a master of black-and-white landscape photography. The first pinhole camera was created by Chinese philosopher Mozi in the 5th century BCE. Dorothea Lange's "Migrant Mother" (1936) is a famous example of photojournalism. Walker Evans' "American Photographs" (1938) is a classic example of documentary photography. Richard Avedon's "Dovima with Elephants" (1955) is a famous portrait photograph. The darkroom is where photographic prints are developed and processed. Development involves exposing the print to light, then treating it with chemicals to reveal the image. Editing is the process of manipulating a photographic image to enhance its aesthetic appeal. Adobe Photoshop is a popular editing software used by photographers and artists. Aerial photography refers to any photography captured from an elevated perspective. Drone photography specifically uses a remote-controlled aircraft. Exposure is controlled by adjusting the aperture, shutter speed, and ISO. Aperture is the size of the camera's aperture, which controls the amount of light that enters the lens. Shutter speed is the length of time the camera's shutter is open, which controls the amount of light that enters the lens. ISO is the camera's sensitivity to light, which affects the image's noise and grain.
