  • Lower ISO settings (e.g. ISO 100) are less sensitive to light and are usually used in well-lit situations.
  • Higher ISO settings (e.g. ISO 1600 or above) are more sensitive to light and are typically used in low-light conditions or when you need faster shutter speeds.
  • However, higher ISO settings can lead to more digital noise in your photos, so it’s important to find a balance between sensitivity and image quality.


  • Aperture controls the amount of light that enters your camera through the lens.
  • Aperture is measured in f-stops, with smaller numbers (e.g. f/2.8) indicating a wider aperture and more light entering the camera.
  • A wider aperture is useful in low-light conditions or when you want a shallow depth of field with a blurred background.
  • On the other hand, a smaller aperture (e.g. f/11 or f/16) lets in less light and is suitable for well-lit scenes or when you want a larger depth of field with more of the scene in focus.

Shutter Speed

  • Shutter speed determines the length of time that the camera’s shutter is open, allowing light to reach the image sensor.
  • A faster shutter speed (e.g. 1/1000s) freezes motion and is ideal for capturing fast-moving subjects or sports events.
  • A slower shutter speed (e.g. 1/30s) allows for longer exposure times and can create motion blur, which is useful for capturing flowing water or light trails.
  • For astrophotography, longer shutter speeds (e.g. 10-30 seconds) are often used to capture the faint light of stars and other celestial objects.

Choosing the Right Settings

  • When starting out, it’s best to use the camera’s Auto mode or semi-manual modes like Aperture Priority or Shutter Priority.
  • In these modes, the camera will automatically adjust the other settings (ISO or shutter speed) based on your chosen aperture or shutter speed.
  • As you gain more experience, you can experiment with manual mode and fine-tune the settings to achieve the desired exposure and creative effects.
