What does the 3D photography function of digital camera mean? How to use it? Urgent! Urgent!

In the past, a prism was added in front of an ordinary camera to cast images on the left and right sides of the film. But usually stereoscopic photography is a double lens.

Kodak once produced small cameras with two lenses. It seems that other companies have done it.

Recently, 3D camera shooting should be realized. On the one hand, there are special 3D camera accessories, or some cameras have dual lenses. On the other hand, 3D TV is not very expensive. The content of 3D is easy to make people dizzy. Not suitable for long-term viewing.

Others, on a long tripod, installed two cameras of the same model, and let them press the shutter at the same time through the remote control. The image taken in this way is actually not as good as two lenses of a camera.

If it is still life photography, you can also shoot the same object with two cameras from different angles.

3D photography requires special software. There are two kinds, one is to convert photos into 3D photos that can be displayed on a 3D screen. The other is to form a 3D model directly from photos. A CAD manufacturer pushed a set of software for free trial a few days ago, but unfortunately it can only run on mac.

If you use DIY to do 3D photography, it is actually easy as long as the camera shooting angle is relatively fixed. After shooting, it is displayed on both sides of the screen, and then watched with a "stereo mirror".

In the past, people used stereoscopes to watch aerial photos through remote sensing. It's just a magnifying glass with a stand.
