Low ISO

High ISO

You can see from the pictures the higher ISO has many boxes that we called it as noise than lower ISO which you don't want to get.

The range of the ISO is around 100 - 6000. The maximum ISO that a camera can achieve is depends on its model. It might be hard to control the ISO in the beginning but the more you practice the better you will be because PRACTICE MAKES PERFECT! :)
