ISO = Sensor Sensitivity

Images > Image Sensor
ISO settings determine howsensitive the sensor is to light
ISO 100 = least sensitiveISO 6400 = most sensitive

Understand the difference in ISO 1600+
ISO TIPS
Turn off Auto ISO
Use ISO 100 – 400 when available light is adequate
In low light, use a tripod to keep ISO at 100 – 400 and leave shutter open longer

A wider opening gathers more light, so the shutter can be faster.
