Re: I am confused. Anyone understand this new 3-D Facebook app?

Here's an image of a modern smartphone with dual rear cameras:

Note the separation is only about 1/2".

One camera is 13 MP color, the other 2 MP B&W. This arrangement is sufficient to generate a depth map file, but is FAR from being capable true stereo photography.

One smartphone was made the DOES produce true stereo photos. That was the HTC EVO 3D. It also had a lenticular (glasses-free) stereo screen for stereo viewing.

The cameras are equal, 5MP color, with a separation of about 1 1/4". Note that the name used here is 3D, and is actually stereo!

Oh, and it takes stereo videos as well as stills...

About $30 or less (used) on eBay.

About depth maps (also called disparity maps)...

Here is what a depth map image looks like. Note that the shade of grey represents the values of the "Z" axis...kinda crude!

BTW, StereoPhotoMaker WILL generate a depth map, and enable uploading the "3D" files to Facebook.
