What is the purpose of using diffusion or light tents on a lighting setup?

• A. To project patterns onto the subject.
• B. To block all light from a source.
• C. To soften and spread light, reducing harsh shadows and controlling highlights.
• D. To change color temperature of lights.

Answer: (C)

Diffusion and light tents are used to soften and spread light by making the source appear larger relative to the subject. When light passes through diffusion material or bounces around inside a light tent, it is scattered in many directions. That scattering reduces contrast, softens shadow edges, and prevents harsh hotspots, producing more even illumination.

This softer, wrapping light is especially helpful for portraits, where it smooths skin tones, and for product photography, where it minimizes glare on shiny surfaces and preserves detail. You can dial in the look by adjusting the diffusion material, the distance from the subject, and the tent size—the goal is to control how soft or subtle the light becomes.
