The first three-dimensional projection was conducted in the United States in the 1920s. On a larger scale, three-dimensional films appeared in the 70s and 80s, also in the USA. At the same time, the inhabitants had the opportunity to view three-dimensional images in Baikal's cinema. Commune ruled, and then Soviet productions were as gray as communist life.
Since James Cameron's "Avatars" premiere everything has changed. Like mushrooms after the rain, there are more movies that unfortunately have nothing to do with the effects that Cameron achieved in his film. Their creators are only attracting the viewer to the cinema and of course the profits from the tickets sold. Judging by the movie rooms, most of us are fooled into thinking that.
In my opinion, 3D productions should strive to achieve such effects that we can see practically only in cinemas specially created for this purpose. If I go to a 3D movie, let butterflies fly around me, it's raining and the train's going to scare me! I want to feel this thrill of emotions, not just to see the depth of space that is ubiquitous in the latest productions.
Unfortunately, the possibility of making big money was also noticed by producers of RTV devices. In fact, for the past two years, we've heard new 3D TVs, Blu-ray players, cameras, and even recently launched a portable gaming console.
First time with a three-dimensional TV home I was in contact in 2010 at the Consumer Electronics Show in Las Vegas. From this event all the fairs have become boring. The whole business centered around the devices that display the image began to revolve around 3D. In addition, special glasses - passive or active (snapshot) are required for watching movies and 3D images. This is probably one of the biggest disadvantages of this technology. The glasses are mostly big, uncomfortable and ugly, and why should I wear them if I have good eyesight? Maybe to spoil it?
"A 3D image may have a potentially negative effect on the user, causing motion sickness, vision problems, confusion, eye fatigue, or problems with maintaining a good posture ..."
Of course, long fatigue before the computer monitor can also cause posture defects, but such warnings freeze the blood in the veins. What to do with this? Buy a new TV or not?
First of all, to get the true 3D effect you need a big screen. The best cinema. At home the best would be a diagonal television more than 50 inches. When buying a smaller LCD, we will see a spatial effect, but for me it is only a substitute for real cinema.
Fortunately, 3D TVs display a normal image, so if you are wearing the intention of changing your receiver, you may want to buy the more advanced one, just in case, because maybe in 10-20 years all programs will be broadcasted in this technology.
Besides, the TV itself will allow you to watch what the TV stations broadcast. According to the manufacturers to watch the 3D movie released on the disc, you need a Blu-ray player. Another expense, but do you really need it? Since normal delivery using the spread method can be three-dimensional, why should we buy the player? And above all, what can we reproduce on it? So far not very much. The 3D version of Avatar on Blu-ray Disc media is exclusively offered by Panasonic, along with its Blu-ray Disc players and 3D TVs, until the end of February 2012. This is probably the best example of pulling money out of our pockets.
But that's not all. At the recent Mobile Equipment Show (MWC) in Barcelona, I saw a mobile phone that offered a 3D image without having to wear glasses. The effect in my opinion is miserable, because what space can be seen on a 4.3 inch monitor, even without glasses? Not many, five of the phones I tested, three could not even run cameras (with two lenses) or 3D applications at all. The problem proved to be easy to solve, it was necessary to restart the device, which started working properly. Just how long?
"Some 3D images can stun people watching them. Older people, pregnant women, people suffering from epilepsy or other serious illnesses should avoid viewing 3D images. "
After all, games are most often used by kids. Should they do it under the supervision of a doctor, and in every game room should a small medical clinic operate? You can do the opposite and transfer gaming rooms to hospitals. There, our children will be safer.
