How to work the constant light in the photo or video studio?

Updated: Apr 7

Constant light, often used in both photography and videography, provides a steady, unchanging light source throughout its use. Unlike pulsed light, which emits a brief flash, constant light remains on, offering continuous illumination. This type of lighting is versatile, used in a range of settings from professional studios to on-location shoots, and it's beneficial for its immediacy and predictability.

Key Features of Constant Light

  • Immediate Feedback: The continuous nature of the light allows photographers and videographers to see the lighting effects in real-time, making adjustments to compositions, shadows, and highlights on the fly.

  • No Synchronizers Needed: Unlike pulsed light that requires synchronization with the camera’s shutter, constant light is always on, eliminating the need for synchronizers.

  • Versatility: Can be sourced from a variety of light types, including LED panels, tungsten lights, and even household lamps or mobile phone lights.

  • Visual Control: Offers the ability to visually adjust lighting setups before taking the shot, providing a direct understanding of how lighting will affect the final image.


Advantages and Considerations

  • Visibility of Effects: Allows for real-time adjustments and precise control over shadows and highlights, making it especially useful for beginners to understand lighting effects.

  • Atmospheric Shooting: Ideal for creating atmospheric or moody imagery with visible light patterns and textures, as well as for video production due to its constant output.

  • Shutter Speed Flexibility: You can experiment with different shutter speeds without affecting the light's output, unlike with pulsed light where the flash duration can influence motion blur and exposure.


Challenges

  • Ambient Light Sensitivity: Constant light sources can be affected by other ambient light within the scene, requiring careful control of the environment to maintain consistent lighting conditions.

  • Increased Risk of Motion Blur: With continuous light, especially in low-light conditions, there’s a higher likelihood of motion blur, necessitating the use of higher ISOs or wider apertures to compensate.

  • Potential for Dazzling: Constant, direct light can be more dazzling or uncomfortable for subjects, particularly with intense sources aimed directly at the face.


Best Practices for Using Constant Light

  • Control the Environment: Ensure that external light sources like windows or room lights are managed to maintain consistent lighting conditions.

  • Monitor ISO and Shutter Speed: To minimize noise and avoid motion blur, adjust your camera settings according to the light's intensity, balancing ISO, shutter speed, and aperture for optimal exposure.

  • Use Modifiers: Softboxes, diffusers, and reflectors can soften the light, reduce harsh shadows, and manage the light’s directionality for more flattering portraits or scenes.


Conclusion

Constant light offers a practical and intuitive way to illuminate subjects for photography and videography, providing immediate visual feedback and continuous illumination. Its versatility and ease of use make it a favored choice for many creatives, from novice photographers learning about lighting to professionals seeking consistent illumination for video shoots. Understanding how to effectively use and control constant light is key to harnessing its full potential in creating compelling visual content.
