Grid cloth is a type of fabric used in film and video production to diffuse light. It is designed to spread and smooth out the beam of light that is projected onto a subject, creating a more even and diffused light source. The result is a reduction in harsh shadows and a more even distribution of light across the subject.
Grid cloth is often used in conjunction with lighting fixtures such as softboxes, beauty dishes, or other light modifiers. The fabric is placed over the light source to create a softer, more diffused light, which can be particularly useful for portrait or product photography.
The degree of diffusion provided by grid cloth can vary depending on the fabric's density and thickness. A thicker, more densely woven grid cloth will provide more diffusion than a thinner, less dense fabric. The level of diffusion can also be adjusted by moving the fabric closer or farther away from the light source.
