Diffusers

Definition

Diffusers are tools used in lighting to soften and spread the light, creating a more even illumination and reducing harsh shadows. They work by scattering the light from a source, making it less intense and more flattering for subjects, which is particularly important in visual storytelling and capturing footage. Understanding how diffusers affect light quality can greatly enhance both the aesthetics of a shot and the overall atmosphere of a scene.
