The Loreo Lite viewer is perfect for viewing stereo images taken with the Loreo 3D lens or the analog camera. The viewer also works with parallel stereo photographs taken by other cameras, as long as the left and right images are side-by-side. The Loreo Lite viewer has great lenses and gives a good clear view. The viewer can not only be used for printed photos, but also for images on a computer screen, provided that they have the proper format. The Loreo Lite viewer is folded very thin and easy to store and mail.
