Learn how to set up the Aputure Light Box 45x45 to soften your LED key light for interviews. Follow these steps for flattering, controlled lighting.
Quick answer
To soften an LED key light for interviews with the Aputure Light Box 45x45, mount the softbox on a Bowens-compatible light, position it close to your subject at a 45-degree angle, and use the inner baffle and front diffuser to control contrast. This setup reduces harsh shadows and creates a flattering, even key light.
Why the 45x45 size works for interviews
The square 45x45 cm surface provides a compact yet soft source that is ideal for small spaces and solo interviews. It balances softness with control, making it a practical choice when you need a flattering key without a massive footprint. Keep in mind that because the box is relatively small, placing it very close to the subject is essential to achieve noticeable diffusion—otherwise the light remains somewhat specular.
Bowens mount compatibility and setup considerations
The Light Box 45x45 uses a Bowens mount, so it fits a wide range of LED monolights and strobes. Before mounting, check that your light's mount is compatible and that the softbox's speed ring aligns properly. A common oversight is forcing the mount—if it doesn't seat easily, recheck alignment rather than applying excessive force, which can damage the mount or the softbox.
Step-by-step setup for interview lighting
- Mount the softbox on your LED light: Align the Bowens mount and secure the softbox to your light. Ensure the speed ring is fully seated and locked. Common mistake: not tightening the mount fully, which can cause the softbox to rotate or detach during adjustment. Double-check that the softbox is securely locked before positioning.
- Attach the inner baffle and front diffuser: Install the inner baffle first, then the front diffuser. This two-layer diffusion softens the light and reduces hotspots. Common mistake: skipping the inner baffle, which results in less even diffusion and a brighter center. Use both diffusion layers for the softest, most even output.
- Position the light at a 45-degree angle: Place the softbox at roughly 45 degrees to the subject's side and slightly above eye level. Aim for a distance of about 3–5 feet for a balance of softness and falloff. Common mistake: placing the light too far away, which reduces softness and creates harder shadows. Closer placement increases softness—move the light in until you see the shadows soften.
- Adjust power and check for flicker: Set your LED light to the desired intensity and verify there is no flicker on camera by checking your monitor or testing a short clip. Common mistake: ignoring flicker caused by incompatible dimming or shutter speed, which can ruin footage. Always test-record a few seconds to confirm flicker-free performance.
- Fine-tune the fill and contrast: If shadows are too deep, add a reflector or a second light on the opposite side. If the light is too flat, move the softbox slightly further away or adjust the angle. Common mistake: overfilling and losing all contrast, which makes the interview look flat. Aim for a gentle shadow on the far side of the face to maintain depth.
