3D has been around for more than 50 years movies in the 1950s from Alfred Hitchcock and other directors being good examples but its never been viable for those wanting to do it for themselves. Its not just that its been hard to find a way to shoot your own 3D pictures easily, but it was a battle in itself to find a way to look at them. But now that everyone has a cell phone camera, and there are 3D-capable TVs, things are different. Thats especially true with the TVs, for the following three reasons:

A BIG SCREEN will let more than one person see the 3D photo that is playing on it: because while the sweet spot for seeing 3D on a TV is dead center, having a bigger screen expands this space so you dont have to be right in the middle.

The HIGHER RESOLUTION of HDTV and, especially, 4K UHD TVs are able to delineate the differences in the image that make the 3D perspective apparent. You need to have the ability to display a high contrast without destroying detail in order for 3D to stand out. Now it can.

The ease in which a 3D image can now be displayed on a 3D-capable TV means that nobody has to be a rocket scientist in order to make it happen. Its a simple matter now of taking out the memory card from the camera and plugging it into one of the TVs USB sockets (with a SD adapter) or connecting a cable between the TV and the camera or sending the info wirelessly (for example, through a WiFI connection or a WiFi memory card). Then the TV just needs to be set to 3D and the picture put up on the screen to look at (with the TVs accompanying 3D glasses now put on).
So that takes care of how well view 3D. So lets go into how we can shoot it. While there are specialized cameras that have 3D built into them, to be readily accessible the camera needs to be right there in most peoples hands. Or pocketsbecause the smartphones that everyone carries around have good quality cameras built right into them. So there are phones which have 3D-shooting capabilities already. And the phones already have the means for getting their pictures sent to the TV through WiFi and other means. But what if your phone doesnt have 3D? Then itll need help for shooting in the third dimension and thats where the 3D accessories come in.

The way these 3D accessories work is that the phone goes inside of them so that an optical system consisting of 2 lenses and a mirror (to simplify) can shoot what is being looked at and save it on the smartphone as a stereoscopic image. An example of this is the Poppy 3D, which works with Apple iPhones 4th and 5th generation (and 5th gen iPod touch).

Theres even newer forms of 3D-compatible devices coming out: an example being the Bevel, created by the same folks who created a 3D scanner. The Bevel will attach to the phone and use its own optical system to turn what is being seen into 3D. One advantage here will be that the 3D image can be used in social media applications or as files for 3D printing as well as being on a TV and looked at.

As can be seen, having 3D pictures can be fun because the process of making and, most importantly VIEWING them has become so much simpler than it was in the past. Be seeing you in the third dimension!
