3D Camera is an app that does just one thing, and does it well: creates 3D photos. Love it or hate it, 3D is here to stay. I thought it was dead for a while, after the cheesy 3D films of my childhood, but Avatar brought it right back to the front and center of pop culture. Want to get in on the trend? Well, I don’t know how to make a 3D movie, but you can certainly create your very own authentic 3D (and mock 3D) photos.
