Cinematic Video in 5 Minutes: The Rule of Three Sources

Whether you are shooting a TikTok or a corporate interview, the foundation of professional video is the 3 point lighting setup. It separates amateurs from pros, and it is surprisingly easy to master.

 A clean, minimalist vector diagram of a 3-Point Lighting Setup. A central subject. A "Key Light" (brightest) at 45 degrees. A "Fill Light" (dimmer) on the opposite side. A "Backlight" behind the subject. Labels are clear and professional.

Source 1: The Key Light

This is your primary light. Place your main Skytex softbox at a 45-degree angle to your face. It provides the main illumination and defines the shape of your subject.

Source 2: The Fill Light

The Key light will cast shadows on the opposite side of your nose. To soften these, use a second light (The Fill) on the opposite side. It should be roughly 50% as bright as the Key light. If you don’t have a dimmer, simply move the Fill light further back.

Source 3: The Backlight (Rim Light)

This is the secret sauce. Place a light behind the subject, pointing at their shoulders/hair. This creates a “halo” effect that separates the person from the background, giving the video a 3D look.

Conclusion

Don’t just blast light at your face. Build the scene. Try this setup once, and you will never go back to single-source lighting.
