Exposure comes from how much light reaches the sensor and how the camera records it. Three settings affect that result in different ways: shutter speed changes motion blur, aperture changes light and depth of field, and ISO changes the camera’s signal amplification.

Quick steps

  1. 1.Photograph one stationary subject in daylight.
  2. 2.Try a faster and slower shutter to see motion differences.
  3. 3.Compare a wide and narrow aperture if your camera supports it.
  4. 4.Raise ISO only when the light and shutter require it.

Shutter speed controls movement

A fast shutter helps freeze children, animals and sports. A longer shutter allows more light but can blur moving subjects or camera shake. If the subject is moving, raising brightness later cannot restore details lost to motion.

Aperture affects background blur

A wide aperture, written as a smaller f-number on many cameras, can separate a subject from the background. A smaller aperture often keeps more of the scene sharp, but needs more light or a slower shutter. Phone cameras may have mostly fixed apertures.

ISO is a trade-off

Higher ISO helps you use a faster shutter in poor light, but can increase visible noise depending on camera and processing. Auto ISO is fine for learning when you still control the shutter or exposure compensation.

One thing to watch

A high ISO photo with sharp faces can be better than a very clean photo where everyone is blurred.

Common question

Which camera setting should a beginner learn first?

Shutter speed is a useful first lesson because motion blur cannot always be repaired later.
