With this texture edit, you can take the texture of any object and add it as the texture of your hair or face or anything. It can make you look as though your face is peeling or decaying!
The ISO setting decides whether the picture being taken is in a higher sensitivity or a lower one. The higher the sensitivity, the less light is needed in an exposure. I enjoy being able to choose if I think the scenery will need a much higher or a more lower ISO. The lower the number you choose, the less "noise" you will have which is more appealing in a picture.
