3D has been around for more than 50 years — movies in the 1950’s from Alfred Hitchcock and other directors being good examples — but it’s never been viable for those wanting to do it for themselves. It’s not just that it’s 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 , things are different. That’s especially true with the TVs, for the following three reasons:
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 don’t have to be right in the middle.
The HIGHER RESOLUTION of HDTV and, especially, 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. It’s a simple matter now of taking out the memory card from the camera and “plugging” it into one of the TV’s 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 TV’s accompanying now put on).
So that takes care of how we’ll view 3D. So let’s 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 people’s hands. Or pockets…because 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 through WiFi and other means. But what if your phone doesn’t have 3D? Then it’ll need help for shooting in the third dimension and that’s 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 iPhone’s 4th and 5th generation (and 5th gen iPod touch).
There’s 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 and looked at.
