Why Replace Your Camera's Light Seals?

Over time, original camera foam seals degrade, crumble, or compress permanently — leading to light leaks that ruin film exposures. Fresh, properly fitted light sealing foam restores your camera to like-new light-tight performance, protecting your film and your shots. This is an essential maintenance item for any large format film photographer.
