Before scanning, your slides are cleaned with low pressure air to remove any dust that may have collected on your slides. This is the safest way to clean slides. Because slide film is enclosed in a frame, we do not clean your slide with chemicals as this would only push the dirt around possibly scratching the film or making streaks on the film slide. Your slides are then scanned at a very high resolution using our Professional film scanner with digital ICE technology. ICE digitally removes any dust in the scan image that may have been left on the slide. ICE doesn’t actually clean your slide, it’s a process that uses light to check for dust left on a slide then removes it from the digital image. This result in a very clean, sharp digital image of your slides.
