I learned that ISO determines the sensitivity to light that goes in the camera. It could make your image blurry or grainy if not set right.

The aperture setting is used to monitor how much light goes through the camera hole.

The shutter speed controls how long the camera lense is open. Slow shutter speed can cause motion blur which is sometimes needed.

There are many camera modes such as auto, program, aperture, priority, shutter priority, manual, and bulb. We will be starting with manual to really learn how to use a camera.
