According to Red Star News news, in 2009, " Avatar " was released globally, setting off a 3D movie viewing craze around the world and leading audiences into a new 3D era. Thirteen years have passed, and watching 3D movies is nothing new for audiences. With the changes in audience viewing habits and the iteration of film technology, audiences no longer buy into "fake 3D" and shoddy 3D films, and they are increasingly pursuing a more extreme viewing experience.
"Avatar: Path of Water" (hereinafter referred to as " Avatar 2") is currently being screened. Some viewers reported on Weibo that they felt dizzy when watching the 3D version of "Avatar 2", and some screens were not bright enough. What's going on?
Why did I feel dizzy while watching "Avatar 2"?
After "Avatar 2" was released, some viewers said that the 3D effect of the film was satisfactory, but they felt that the screen brightness was not enough during the viewing process, making people dizzy. Chen Yu, technical director of
RealD Asia Pacific, has a deep understanding of the principles of 3D projection technology and leads his team to provide technical support to theaters. He explained the reasons.
3D glasses separate the two images of a person's left and right eyes, so that the left eye can see the image of the left eye, and the right eye can see the image of the right eye. At the same time, it is projected onto the person's retina, forming a three-dimensional, virtual experience. Through the separation and convergence of the left and right eyes, it creates an illusion and "deceives" the nerves of the brain. The more realistic a 3D movie is, the more frequently its perspective changes and depth of field shift will occur.
When the human eye transmits the information that it is "moving" to the brain, the brain does not feel the signal from the body's muscle movement, resulting in a certain perceptual error. In this state for a long time, it varies from person to person. Some people feel lighter, while others feel very uncomfortable. In addition, the brightness during 3D screening is extremely low, the overlap in theater debugging is not very good, and the subtitles are not very clear. The sum of these will cause a feeling of dizziness.
To put it simply, on the one hand, it is affected by its own physiological reasons, and more importantly, the output of the equipment and products is not very good.
Which theaters have relatively higher brightness?
This time, Cameron "Avatar 2" has been upgraded compared to the first production, using 3D/4K/48 frame shooting technology. Previously, Ang Lee had used 3D/4K/120 frame high-standard technology in "Billy Lynn's Midfield War" and " Gemini Man ". At present, domestic theaters that fully support 3D/4K/48 frames include CINITY, IMAX second-generation laser theater, and Dolby Cinema, each with its own characteristics. The official Chinese subtitle poster released by "Avatar 2" shows that
has five supported formats, namely CINITY 3D, IMAX 3D, Dolby 3D, China Giant Screen 3D and ordinary 3D full version. Many fans reported that "Avatar 2" was relatively brighter in CINITY Cinema, Dolby Cinema, and LUXE Giant Screen Hall.
RealD Asia Pacific Marketing Director Yu Shenglun said that "Avatar" 13 years ago brought 3D to the world. Nowadays, 3D viewing has become common, and audiences have slowly begun to form the habit of "choosing 3D or 2D."
When "Avatar" suddenly became popular, many movie theaters had no idea what 3D was about, so they actively bought a batch of shutter-type 3D glasses. However, they may not know that 3D projection has brightness problems, or they may not know whether 3D ghosting is what natural 3D should have.
More than ten years later, through the joint efforts of the industry and the audience, everyone knows that 3D cannot be viewed too dark, or that ghosting is wrong. Projectionists have also begun to receive professional training and know how to project 3D movies better. For example, the LUXE giant screen hall with high frame rate 3D projection capability has double light effects and ultra-high brightness RealD 3D, which brings 1.85 times the amount of light to the traditional screen. The 3D image brightness can reach 12FL, thus greatly eliminating ghosting and discomfort caused by 3D projection.
With the development of film technology, 3D film equipment has gradually become the mainstream of cinemas. When "Avatar" was released, there were about 6,000 3D screens in the world, nearly half of which were in China.Today, there are more than 60,000 3D screens in China and more than 120,000 3D screens around the world. In addition to foreign brands such as IMAX, domestic projection technologies provided by China Giant Screen and CINITY are gradually being accepted by audiences, giving audiences more choices.
