CHOOSING ISO IN PHOTOGRAPHY

     One of which must be determined before the shooting is ISO. ISO is the sensitivity of the sensor, where the higher the ISO the more bright picture, but if its too high ISO, image quality decreases (there are spots / noise, color and detail to fade)

      Ideally we settng ISO to the lowest number such as ISO 100 or ISO 200 when we are shooting on a sunny day, and we raise the ISO when shooting in a dark room.
To determine the ISO is the light by the environment and the type of photography.
Below are some ISO value used for photographing

ISO 100 to 200 is used for shooting on a sunny day, outdoors, or if we use the lights FLASH

ISO 400 is used to take pictures when the weather is cloudy, the afternoon before sunset

ISO 800 is used to take pictures in the room with bright lights.

ISO 1600 is used for taking pictures indoors

ISO 3200 is used to take pictures in a dark room, shortly after sunset

ISO 6400 is used to take pictures in the room with a small lamp
