Exposure is used all over in America and the world in photography.Exposure has been used by many photographers all the way from the average bum on the street to Ansel Adams. If exposure is used rightly it accurately represents light and color correctly through the image. Also in the blacks and whites the detail is still shown no mater how dark or how bright. Exposure is consisted of three main things. The first one is aperture, aperture is the size the hole that light is able to travel through. The second one is shutter speed, shutter speed is how long the shutter is opened for. Then lastly there is ISO, ISO is a measure of how sensitive your film or sensor is to light.
With all three of these working together this is what creates the perfect exposure. In combination with variation of shutter speed, the aperture size will regulate the film's degree of exposure to light. Typically, a fast shutter speed will require a larger aperture to ensure sufficient light exposure, and a slow shutter speed will require a smaller aperture to avoid excessive exposure. Areas of a photo where information is lost due to extreme darkness are described as crushed blacks in the photography world. Digital capture tends to be more tolerant of underexposure, allowing better recovery of shadow detail, than same-ISO negative print film. Ansel Adams was an American photographer and environmentalist, best known for his black-and-white photographs of the American West and primarily Yosemite National Park. He developed the zone system, a way to determine proper exposure and adjust the contrast of the final print. The resulting clarity and depth characterized his photographs. Although his large-format view cameras were difficult to use because of their size, weight, setup time, and film cost, their high resolution ensured sharpness in his images. While the technology was worse then, then now Ansle Adams still used Aperture, Shutter speed, and ISO to get the perfect exposure.
All in all exposure is used all around the world. The perfect exposure always consists of aperture, shutter speed, and ISO. Again aperture is the size the hole that light is able to travel through. Shutter speed is aperture is the size the hole that light is able to travel through. Finally ISO is a measure of how sensitive your film or sensor is to light. If you over expose your picture it will be too bright and if you under expose your picture it will be to dark. So can exposure ruin your picture or it can make your picture a lot better and more detailed if you get the perfect exposure.
