If we have a 5K Fresnel projecting through a 12x12 diffusion, which component acts as the source?

• A. The 5K Fresnel
• B. The 12x12 Diffusion
• C. The Light's Filament
• D. The Subject

Answer: (B)

Diffusion defines the apparent light source. When light from the 5K Fresnel passes through a 12x12 diffusion panel, the panel scatters the light and creates a larger, softer emitting surface. The camera and subject perceive light as coming from that diffusion plane, so the diffusion itself becomes the source in the shot. The original lamp (the Fresnel) still provides the light energy, but the visible, soft source the lens sees is the diffusion. The filament is the actual emitter inside the lamp, not the source as seen in the scene, and the subject is simply being illuminated by that light.
