Please refer to How to Free View a Stereo Pair

Steps in order to phone freeview:

Step 1 : Take a picture of a subject.

Step 2 : Move your camera about 3 inches to the right (the distance between your eyes) and take a second picture of the subject. These two pictures are called a “Stereo Pair”.

Step 3: Using your favorite photo editing app, create a new photo consisting of the stereo pair placed side by side in landscape view (I personally upload 2 images to Microsoft Word and then take a screenshot). This new photo can then be shared to your friends for device-free 3D viewing.
