Lowry Digital uses more than 300 computers and more than 40 terabytes of computer space in its restoration efforts. Technicians scan and convert motion-picture imagery into digital information at high resolution, and examine it frame by frame for imperfections. They correct flaws using proprietary software. "We will do a number of things with the granularity, sharpness and the stability of the images, dirt, scratches, flicker ?the whole range of things that really come about from film being used over and over through the years," Lowry says. "For example, in some movies, we deal with hundreds of pieces of dirt per frame ?literally millions of pieces of dirt that we have to remove in a motion picture. In the case of the Indiana Jones films, we had maybe 100,000 pieces of dirt per movie. Now, that sounds like a lot, but when you have 172,000 frames, it's only one piece of dirt, on average, every frame or every second frame."

Enhancing the detail of the original photography also enhances defects dating back to the time of production. Even these, though, can be corrected ?provided they do not compromise or alter the director's envisioned shot. In one scene originally filmed in front of a bluescreen, for instance, the image "ended up with blue 'fringing' in the shot, and this has been in the movie since day one: a blue fringe around all of the edges," Lowry says. "When we enhance it and clean it up, it looks pretty ugly." After working on the shot for just a half an hour, "We had removed all of the blue fringing. It's an example of an interesting little case where something could easily be cleaned up by using our automated processes."

While the ability to alter these imperfections is powerful, Lowry's technicians take great care not to tamper with the content of the original image. "Rather than dealing with art, we tend to deal with science," he says. "For example, we make very little, if any, change to the contrast or color or things of that nature. We are not in the color-correction business, because that is an art. We can improve the overall quality of the picture, but generally speaking, we try to do it from a very scientific perspective. It is extremely important that we do everything we can not to impair what the director or cinematographer was trying to do in the first place."

Having restored such landmark titles as Sunset Boulevard, North by Northwest and Snow White and the Seven Dwarfs, Lowry says he is happy to add the classic Indiana Jones series to his company's roster. "Oh, I love it," he says. "It's a joy to work on movies of this caliber."

The filmmakers, meanwhile, are equally happy, says Jeff Radoycis, Senior Vice President of DVD Production for Paramount Pictures. "The work that Lowry Digital Images did on the Indiana Jones movies was so tremendous that it made the people who created these films look at them in an almost brand-new way."
