The Light Dome III is designed to provide versatile lighting options for various shooting requirements.

• Light Softness Control: Utilize the two densities of diffusion fabrics (1.5 Stop and 2.5 Stop) to achieve your desired level of light softness. Use both for maximum diffusion, or one for a slightly harder but still soft light.
• Light Direction and Contrast: The included 40° fabric light control grid helps to narrow the beam spread and increase contrast, allowing for more precise lighting control and dramatic effects.
• Circular Eyelights: The 32-sided circular design of the Light Dome III creates perfectly round catchlights in your subject's eyes, mimicking natural light sources and adding a professional touch to portraits.
