When you as a photographer – amateur or professional, analog or digital – practice your craft or hobby, you will at one time or another become acquainted with the three letters ISO.If the camera does not get enough light onto the sensor or film, the images will be too dark.

To correct this you can set a higher value on the ISO. All photographers are dependent on light and lighting conditions can be very variable at different locations or times of day. The ISO value is for that reason an important tool that allows the photographer to be able to work effectively in many different lighting conditions.
