As a beginner in photography, here are five essential camera settings you should learn:

  1. Aperture
  2. Shutter speed
  3. ISO
  4. White Balance
  5. Focus


The aperture is the opening in the lens through which light enters the camera. It is measured in f-stops.

  • A lower f-stop number such as f/2.8 means a wider aperture and more light entering the camera.
  • A higher f-stop number such as f/8 means a smaller aperture and less light.

Aperture also affects the depth of field, which is the distance between the nearest and farthest objects in focus.

  • A wider aperture (lower f-stop number) such as f/2.0 will result in a shallow depth of field, which is great for portraits and close-up shots. The subject will be in focus and the background blurred.
  • A smaller aperture (higher f-stop number) such as f/16 will result in a deeper depth of field, which is useful for landscape and group shots. More of the image will be in focus.

Shutter speed

The shutter speed refers to the amount of time the camera’s shutter remains open to allow light to reach the sensor. It is measured in fractions of a second.

  • A faster shutter speed such as 1/2000 will freeze action and reduce motion blur.
  • A lower shutter speed such as 1/20 will create motion blur and give a sense of movement.

Shutter speed is often used in combination with aperture to achieve the desired exposure.


ISO measures the camera’s sensitivity to light.

  • A higher ISO number such as 1600 allows you to take photos in low light conditions, but it can also result in a grainy or noisy image.
  • A lower ISO number  such as 100 is ideal for well-lit conditions and produces a cleaner image.

It is important to balance ISO with aperture and shutter speed to achieve the correct exposure.

White balance

White balance determines the color temperature of your photos. Different light sources have different color temperatures, and adjusting the white balance helps to ensure that the colors in your photos look accurate. Most cameras have automatic white balance settings, but it’s also useful to learn how to manually adjust it.


Focus refers to the sharpness of the image. Most cameras have an autofocus system that automatically focuses on the subject, but it’s also useful to learn how to manually adjust the focus. This is especially important when shooting in low light conditions or when the subject is moving.
