What is Exposure in Video Production?

Exposure in video production refers to the amount of light that enters your camera lens and hits the digital sensor. It’s a crucial concept as it directly impacts the brightness or darkness of your video. Correct exposure is essential to produce high-quality, visually pleasing videos.

Understanding the Basics of Exposure

Exposure is determined by three primary factors – Aperture, Shutter Speed, and ISO. Together, these three aspects form what is known as the Exposure Triangle.


  • Aperture is the size of the opening in your camera lens.
  • It is measured in f-stops, with a smaller number indicating a larger aperture and more light entering the camera.
  • A larger aperture also creates a shallower depth of field, blurring the background while keeping the subject in sharp focus.

Shutter Speed

  • Shutter speed refers to the length of time the camera’s shutter is open.
  • A faster shutter speed allows less light to enter the camera, while a slower shutter speed lets in more light.
  • Shutter speed also affects motion blur – a faster shutter speed freezes motion, while a slower shutter speed creates a blur effect.


  • ISO is the camera’s sensitivity to light.
  • A lower ISO number means less sensitivity to light and less image noise.
  • A higher ISO number increases sensitivity to light, useful in darker environments but can result in more image noise.

How to Achieve Correct Exposure?

Achieving correct exposure requires a balance between aperture, shutter speed, and ISO. Use your camera’s light meter to help guide you towards correct exposure. Remember, there is no “right” or “wrong” exposure, it ultimately depends on the creative look you’re aiming for in your video.

Why is Understanding Exposure Important?

Understanding exposure is fundamental in video production. It enables you to control the look and feel of your videos, from creating depth with a shallow depth of field, freezing or blurring motion with shutter speed, or managing image noise with ISO.

In conclusion, mastering exposure is integral to enhancing the visual storytelling of your video content, whether you are a video editor, filmmaker, influencer, or YouTuber.
