Operating Instructions
1. Using Diffusers
The softbox includes an inner and an outer diffuser. These can be used individually or together to achieve different levels of light softening.
- Inner Diffuser: Attaches inside the softbox to provide initial light diffusion.
- Outer Diffuser: Attaches to the front edge of the softbox to further soften and spread the light.
- Both diffusers are fastened with touch fasteners for easy assembly and removal.

2. Using the Honeycomb Grid
The honeycomb grid attaches to the front of the softbox, over the outer diffuser. It helps to:
- Control and direct the spread of light.
- Narrow the beam angle.
- Reduce light spill.
- Create more focused and directional lighting.
