From my research sources i now know that…
Exposure of a photograph all depends on the amount of light used. The photographs exposure will determine how light or dark the photograph will be. If the photo is too light the image will be over exposed and if the image is too dark it will be under exposed. To set the exposure you need 3 elements of the camera, Aperture, Shutter Speed and ISO. This is known as the exposure triangle.
As the aperture controls the amount of light which can enter your camera and the shutter speed controls the duration of the camera and finally the ISO controls the sensitivity of the cameras sensor to the given amount of light. They all control exposure differently. These three things can all be used in many different ways to to make the correct exposure. The key to correct exposure depends on your understanding of all these three as each one of them has a different image properties and creates different effects within the images. ISO usually ranges from 100, 200, 400, 800, 1600, 3200. However this can vary lower or higher depending on your lens.
