A diffuser is a device used in lighting to soften and spread light evenly across a space. It helps reduce harsh shadows and glare, creating a more pleasant and inviting atmosphere. Diffusers can be made from various materials, such as fabric, plastic, or glass, and are commonly used in photography, videography, and interior design. In addition to enhancing aesthetics, diffusers can improve the functionality of light sources. For example, they are often used with LED lights and fluorescent bulbs to create a more uniform light distribution, making them ideal for settings like offices, studios, and homes.
