Based on filters originally developed by Lee Filters for use in the film industry, the Soft filters take the image from a subtle, barely noticeable softening to a heavy diffusion. Made from the highest quality, optically correct polyester-based materials, these lightweight and inexpensive filters are ideal for every type of portraiture and social photography. Mounted in plastic frames for extra protection, these filters slip easily into the photographer's filter holder system, to give the outstanding results expected from a Lee Filters product.
