Shoot in Low Light
You've met two ways to control light: aperture (the opening) and shutter speed (the duration). ISO is the third — it sets how sensitive your camera's sensor (the chip that captures the image) is to the light it receives. Low ISO (like 100) is for bright days; raise it (800, 1600, 3200…) and the sensor amplifies dim light into a usable picture.
This is your rescue in the dark. Indoors at night, in a restaurant, at a concert — whenever there simply isn't much light and you'd rather not fire a harsh flash — raising the ISO keeps your shots bright and, just as important, fast enough to stay sharp in your hands.
Turn the flash off, find a dim room, and push the ISO up until the picture is bright and free of shake. Notice the number you land on — that's your camera reading the room.
Flash off. Use Auto ISO to watch the camera choose, or set ISO yourself and climb (400 → 800 → 1600 → 3200) until the photo is bright and shake-free. Aperture Priority or Auto handles the rest.
It counts when you get a bright, sharp, handheld photo in a dim room with no flash — and you noticed roughly how high the ISO had to climb. Still dark or blurry? Raise the ISO further (and brace the camera).
The assignment
In a dim room with the flash OFF, raise your ISO until you get a bright, shake-free photo — and notice how high you had to go.
