5 What is ISO?
The last two episodes concentrated on aperture and shutter speed. This time we’re going to look at ISO and how this connects with the other two. What is ISO? Basically, ISO is a measurement of how sensitive your camera is to the available light. The lower the ISO number on your camera, the less sensitive it is, while the higher you go with the ISO numbers, the more sensitive it is. When you increase your ISO above a certain level, you can get more light in low light conditions, but that increase in light comes with a trade-off in terms of picture quality. The higher the ISO, the more digital noise or grain becomes apparent in your images. Noise literally looks like small grains all over your image. You can see an example of this below. This image was taken at high ISO, and if you look closely, you can see tiny specks all over the image, but it’s especially noticeable in the sky areas.
