If you place a 4x4 diffusion in front of a light, does that make it a soft light?

• A. Yes
• B. No
• C. Not necessarily
• D. It depends

Answer: (C)

Soft light comes from a light source that looks large to the subject, which is why shadows are gentle and edges are diffuse. A diffusion panel in front of a light helps by scattering the light and increasing its apparent size, which tends to soften shadows. But a 4x4 panel isn’t automatically large enough to guarantee softness in every setup. The final look depends on how far the subject is from the light, the distance between light and subject, and the overall geometry of the scene. If the subject is positioned far from a relatively small diffusion, the shadows can still read as hard. So placing a 4x4 diffusion can soften the light, but it doesn’t guarantee soft light in all situations.
