What is ISO?
ISO measures the sensitivity of the photo.
The lower the ISO is, the less sensitive it is to light.
The higher the ISO is, it'll be more sensitive to light.
Using higher ISO has an advantage however, it's mostly used in darker situations to have a higher shutter speed and it'll become more clear.
