A survey cited in an eight-year study into the side effects of 3D glasses found only a third of viewers have no trouble, while two-thirds feel some form of discomfort, including 7 percent that report terrible headaches. This is a good time to make a crucial differentiation. There are two categories of 3D movies appearing in theaters today, and they make a big difference in the quality of the production: "real" 3D films that were shot with stereoscopic cameras and created specifically for 3D viewing which is notoriously expensive , and "fake" 3D films that tack on the 3D effect in post-production.
In the former camp are films like Avatar and Gravity that are set in visually stunning worlds designed to be experienced on the big screen in an immersive format. Animated films are also uniquely poised to take advantage of the format and can be even better when seen in 3D.
In the latter camp are a lot of superhero or action or horror flicks that are converted to 3D to squeeze an extra buck out of the audience, but for which adding the dimension of depth does very little to improve the experience. In fact, converting perfectly good films to 3D can make them considerably worse.
Action movies have too many fast cuts for the viewer to get a chance to feel immersed in the three-dimensional world, on top of which your eyes are working overtime to keep up so you're more prone to headaches or feeling sick. A study published in the journal PLOS One found that 3D movie watchers commonly reported visual fatigue like eye pain, headaches, double vision, difficulty focusing and nausea. Plus there are often those cheesy shots thrown in solely to show off the 3D capabilities, like Spiderman flying at the screen and web-slinging toward the audience.
Cinemas are continuously trying to improve the theatre experience and the rise of 3D technology is the latest in a line of improvements.
With the near perfection of 3D technology, more and more films are being offered in 3D format, but are 3D movies really worth it? The big selling point for 3D is that it offers a better, more immersive experience.
Regardless of what you thought of the plot, the film itself was stunning and the 3D technology was used to create good old-fashioned movie magic. Unfortunately, not all 3D films use the technology to this level. I can think of dozens of 3D films that offer no significant difference between the 3D and 2D format. One lens of the polarized glasses views vertical light waves, while the other views horizontal light waves. Again, the image disparity between the right eye and light eye mimics real vision, making the flat image on the screen appear to have depth.
Some doctors recommend surgery, regardless of age, while others find vision therapy helpful. Neuroscientist Susan Barry, who had been stereoblind her whole life, practiced eye exercises to train herself to see depth and successfully developed stereo vision. For at least one person, psychology professor Bruce Bridgeman, watching a 3D movie actually corrected his stereoblindness. However, if you want to try and understand what all this 3D hype is about, visit All About Eyes for a comprehensive eye exam and some expert advice.
Search for:. What is Stereoblindness? Vudu offers half-resolution side by side 3D movies, but the prices are too high making it more logical to buy a better quality 3D Blu-ray. They also disabled 3D playback ability on all but a few older devices, making even people with modern 3D projectors or 3D phones unable to watch them, and no new 3D movies have been added in a couple of years, meaning they probably abandoned it.
The other 3D streaming provider would be for the Red Hydrogen One 3D phone, but again, there are no recent movies and the prices are exorbitant. There was a smart TV app called 3D Crave that enabled rentals of some 3D movies and shorts, but they were bought by Rokit, who have a 3D streaming service for their 3D phones. They announced some time ago that they would soon come to an agreement to rent major Hollywood 3D movies alongside their independent 3D content, but that looks to have fallen through.
What you're describing is the holy Grail of all things 3D, and it would blow the industry open if available. Even today's twin lens 3D cameras can't calculate completely accurate depth maps from a 3D image. Maybe you are in the twilight zone lol. Or the future! Well, its more than that because you can actually see the ball come at you when thrown toward the screen. AND I am not one to easily be conned.
I am a natural septic. Have you seen the LG 60" 3D picture in person. They may not still sell the one I have as I got it about 5 years ago. Maybe from the Twilight Zone. In answer to your question, yes an automated 3D conversion will look blurry without glasses and clear with. However that doesn't mean it's really 3D.
For instance: If I take a photograph and move it back a little, maybe even bend or curve it, it will have dimensionality to it, but there will still be no separation between elements, a person and the wall behind them. Another example: I can take a black and white image and make the whole thing look green. Yes, technically now it is 'color', but it's without regard for the content.
Automated 3D features are similar. They don't typically degrade the picture. They may even add a little 'life' to it, and some enjoy that. But what I'm saying is that it doesn't hold a candle to manual 3D conversion. It was inexpensive and actually cheaper than the non-3D version. I bought it with NO expectation of 3D being usable since almost no 3D programing is available.
But I was very surprised to find it worked on ALL programming. I am an Electronics Engineer with 43 years of programming experience in 13 languages and and I can't imagine how a software algorithm could be developed, and placed as firmware into my TV, to convert flat TV into 3D but they have done it somehow.
I am not imagining it. Depth is fully realized. It is most noticeable at a distance of 8 feet or less and on live subjects like sports. But it also is effective on movies. At 12 feet and beyond the effect is lost. What am I missing here? Social Networking.
