I understand shutter speed but what confuses me is ISO and Apeture. The Apeture is physically the opening which determines how much light comes in , but ISO determines how sensitive the camera is to exposed light.
In: Technology
the biggest difference between ISO and Aperture is the grain of the photo, and the focus. With a high ISO your picture will be grainy, and have a lot of colour “noise”. Aperture doesn’t do this, but instead it shrinks the range that is focused in the picture. the lower the aperture, the more open and less range of focus in the picture, and the higher aperture is the opposite. hope that helps
