Diffusion filters are commonly used by photographers in order to soften skin imperfections and reduce the "digital" look that modern high-quality lenses can create. Once you find a suitable diffusion filter, it can significantly cut down on post-production editing time. The aim of these filters is to soften wrinkles while creating a natural overall effect that makes the subject appear more flawless.
If you are looking to purchase a diffusion filter, there are many brands to choose from, including Tiffen, Hoya, Promaster, Cokin, and more. These brands offer a wide range of filters with different densities, ranging from 1/8 to 5.
