What is 3d?

Each of us has two eyes, and the two eyes form a certain angle, which is reflected in our brain, and there is a three-dimensional image. Take a test, close one eye and touch the pen tip standing on the table with one finger. You will find it difficult.

Stereophotography is based on this principle. Two lenses are used to imitate human eyes to shoot, and finally, after processing, two eyes can see the pictures shot by different lenses, forming a three-dimensional effect in the brain.

At present, there are mainly two kinds of equipment for 3D shooting, one is an all-in-one machine, such as Sony's TD300 and Panasonic's 3d p 1 (not to mention small DV for home use). ); There is also a 3D bracket. Like TS series, ET series, P+S series. At present, stents have been developed in China, but they are still immature.

Although the flexibility of the all-in-one machine is much better, it is necessary to use a bracket to achieve the top effect when shooting in stereo. At present, the best scaffolding in the world is the TS series of 3Ality, and both Spider-Man 4 and The Hobbit prequel are used. What I know is that there is only one company in China called Shen Lan 3D, which has done a lot of stereoscopic shooting, including the recent Guangzhou CBA All-Star, the 20 1 1 Asian Games, Serie A in Beijing Bird's Nest and so on. Relative to China, it should be a stereo shooting company, with very experienced shooting and guaranteed quality.

The stereoscopic effect that a good bracket can achieve is in line with the safety range of human eyes and can save a lot of later costs. And in fact, for 3D, most of the problems in early shooting can't be solved later. So if you want to shoot a good stereo effect, you must find an experienced shooting team and shoot with a stereo bracket.
