Before we go any further, you should first understand how DSLR cameras work. In very basic terms, ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called âimage sensorâ or simply âsensorâ.
In order to control this light, you have the ability to control three separate settings inside the camera. There are two ways to control the amount of light that enters the camera and exposes the photosensitive surface (aperture and shutter speed) and one way to control the sensitivity of that surface (ISO).
