Answer:

ISO tells your camera how much light to add to your photo. ISO is like pulling up the "brighter" slider inside your camera. Your camera is adding light to the photo even though the light isn't there. Because of this, the higher the ISO, the higher the grain.

Answer:

ISO can help you capture images in darker environments, or be more flexible about your aperture and shutter speed settings. Darken and lighten the brightness
