The Mitchell Diffusion Filter is the result of Pancro's patented diffusion process upon a single-piece of optical-select glass. It is available in softness variations of A, B, C, D, and E on all standard sizes including 4 X 5.650 and 6.6 X 6.6.

For many years in the movie industry and continuing today, the Mitchell Diffusion Filter has been used for close-ups to flatter and soften facial imperfections. Often called the actor's best friend, the Mitchell Diffusion Filter softens undesirable features such as freckles, blemishes, and wrinkles. It also creates a romantic ambiance by softening colors and cutting sharpness.

In operation, the Mitchell Diffusion Filter softens an image by refracting a portion of light as it passes through the filter. Whether softening facial features and colors, or cutting sharpness, the final effect on screen is always subtle and unobtrusive. Use of a filter is undetected.
