If you don't use the free-viewing techniques we described or, moreover, you want to show to your friends your stereoscopic photos without asking them to learn it, you can adopt one of the 3D Cross Viewers present in the market.

Actually, the choice, in this case, is restricted to just one viewer: the Loreo 321 3D Viewer.

Its strenght is the easiness in using it.

Pictures (up to roughly 30) are placed in the loader.

People not familiar with stereoscopic pictures tipically need no more than 10 seconds to be able to see in 3D thanks to the predefined distance between the real viewer (in the front) and the loader (in the back). Even people wearing glasses can use it.

In our tests (roughly one hundred people) we didn't find someone not able to perceive the stereo image.

You can turn over the pages exctracting them one by one without diverting your view. This is essential to not tire your eyes and to enjoy the stereoscopic experience. The front of the viewer is detachable and can be used to view the Cross stereo pictures on the PC.

The front part can be lowered over the over the loader (even with the pictures inside!) in order to reduce the occupied space.

Limitations resides in the size of the photo: we suggest the classic 15(width) x 10(height) centimeters. Larger pictures, even with the front detached, are difficult to be appreciated without a period of adaptation or if you don't stand at a greater distance from the photo (which could determine some blur).
