What is ISO? ISO in film is the sensitivity of film to light. Digitally, ISO is the sensitivity of the image to the image sensor.
In the exposure triangle, when ISO is changed, you have to change the shutter speed in order to let more light in or keep light out.
ISO causes grain in the photo when the number is higher, when it is lower, the grain goes away.
