In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography the lower the number the less sensitive your camera is to light and the finer the grain.By choosing a higher ISO you can use a faster shutter speed to freeze the movement,the ISO rating or number is an indicator of how sensitive a camera's image sensor is to light at a specific setting. Changing your camera's ISO setting will amplify or decrease the image sensors' ability to read light during an exposure.When your camera is set to a higher numbered ISO setting such as ISO 800, less light is needed to obtain a correct exposure than if the camera is set to ISO 100 for the same shot. That is, assuming other factors such as the camera lens aperture setting, and the shutter speed setting remains the same.

Some of the most common ISO settings/ISO numbers are listed below.
Every smartphone camera has a different range of ISO values:-
-ISO 100 (low ISO)
-ISO 6400 (high ISO)
What does a higher ISO mean?
The speed or light-sensitivity of a digital camera's sensor is rated in ISO numbers -- the lower the number, the slower the response to light. Higher ISO numbers indicate a higher sensitivity to light, so less time is needed to expose a picture.

Here are some recommendations of what ISO to use in different lighting condition.
-Outdoors with sunny skies: 100-
-Outdoors with overcast, sunrise
and sunset: 200-400
-Well lit interior: 400-800
-Semi-lit interior: 800-1600
-Nightime exterior or dimly lit
-Indoor or nighttime sports: 1600-

Aperture, shutter speed, and ISO make up the three sides of the exposure triangle. They work together to produce a photo that is properly exposed. If one variable changes, at least one of the others must also change to maintain the correct exposure.
