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
ISO is the “sensitivity” of your camera’s sensor. A camera’s ISO generally ranges from 100 (Low) to 3200(High).Using a lower ISO needs you to open your shutter for longer to allow more light in.Shutter speed is the amount of time your shutter is open for. For images of fast moving objects, high shutter speeds are used. But this usually affects how well the image can be resolved by the camera. A high ISO image is grainy, and has more noise;The aperture here means the size of the “hole” used to let in light in. The wider the aperture the more light is let in. Again, this makes it harder to form a clear image.
