How Frame Rate Affects Exposure (Cinematography Basics Explained)

Enjoy this FREE lesson from our Cinematography Course: https://www.videoschool.com/VSOCINEMATOGRAPHY What’s this lesson about? Frame rate doesn’t just affect motion — it directly impacts your exposure. In this lesson, you’ll learn why increasing your frame rate makes your image darker and what you need to do to compensate. As you shoot higher frame rates like 60fps, 120fps, or beyond, each frame has less time to gather light. That means less exposure — and more lighting challenges. What you’ll learn: • Why frame rate should be set before ISO and aperture • How higher FPS reduces the amount of light hitting the sensor • Why slow motion requires more light • The relationship between frame rate and shutter time • When you’ll need faster lenses, higher ISO, or more lighting • Common exposure mistakes when shooting high frame rates Understanding how frame rate affects exposure is a core cinematography skill — especially if you plan to shoot slow motion or cinematic video.
