Digital Film Tools Ozone is a unique filter that allows photographers, designers and artists to manipulate the color of an image with incredible flexibility and accuracy. We like to call our Ozone filter, "The Digital Zone System�. All you need to do is provide the photograph, we provide the digital darkroom. Of course, we prefer that your image is exposed properly and that you capture as much image information as possible.User Interface Ozone is comprised of 2 main components: the Viewer and Parameter window.
