January 2010, "Avatar" opened the first two games, as a 3d lenticular person, must pay attention to any one of the new 3d lenticular changes in the industry.
 
       Resin made with cinema glasses looked for half an hour, I felt something wrong, people on the foreground and background screen upside down, the picture is very dark. I carry a simple red and blue glasses put on, with no 3d lenticular effect. My red and blue glasses only two dollars, and the staff said, "take care of glasses, damaged a compensation 700 yuan."
 
      Inadvertently looked at the glasses upside down, ha, this is just great, realistic lenticular effect out. Safety glasses turned upside down!
 
 Afterwards, I told staff, good check your glasses, many lenses are safe backwards. They do not believe that another woman in the audience to listen to me say, suddenly realized, "No wonder I looked uncomfortable, not always 3d lenticular film."
 
      After returning home, I seriously thought for a moment, it should not be so much safety glasses are anti. Projector will not be a problem?
 
 Carefully looked at the statistics. I took the glasses are polarized glasses, red and blue glasses can not see the 3d lenticular effect. Current domestic lenticular 3D projection technology widely used stand-alone system to Xpan-D and Dolby systems based, glasses, high cost, but big and heavy, so many viewers often complain about pain in the nose and ears see, 3D projection stand-alone system Only when the film source beaming efficiency 10% -15%, which is why I see a 3D movie grayer causes.
 
 Digital 3D cinema systems generally use single-and dual-drive system screenings, stand-alone system in the country is the most common time difference are displayed alternately 3 octave to achieve, although this approach to achieve the 3D, but unfortunately there will be obvious flicker and obvious motion picture blur effect, showing the brightness much lower than the average film also affect the viewing effect.
 
 Another stand-alone system to a higher cost Real-D: Real-D system is the lower cost of passive glasses, a DLP projector, of 144 frames / sec for the alternate left and right eye viewing the projection digital image;, but the screen is plated aluminum metal screen, instead of the traditional white screen, the highest of luminous efficiency. Real-D system in China is not widespread, only Shanghai Kodak Theater an adoption.
 
 There is also a double-double machine Dolby 3D systems. Two machines simultaneously show the contents of left and right eye, brightness can greatly improve; projection systems using dual screens larger than other stand-alone systems, the visual impact is relatively closer to the IMAX DMR. How to tell the same one in which cinema hall with a dual system, you only need to determine which can be a bigger hall. I think the film is a stand-alone show, so definitely glasses installed backwards, not the projector issue.
 
 From the show format, the two kinds of sub-35MM and 70MM film version, 70MM is dedicated exclusively for the IMAX theater, whose role is to increase the image resolution of up to several stories on the giant screen is still delicate lifelike. "Avatar" in the country to film format released in IMAX theaters, only Beijing Film Museum, Shanghai Peace Cinema and Dongguan Wanda three; remainder IMAX theater even in the film hall show, is the digital transformation, that is, the use of digital projectors Play The digital version. The 35MM is only 2D theaters. Zhengzhou no IMAX theater, I see also 35MM digital version after conversion.
 
 "Avatar" Although there IMAX3D version, but it is not true IMAX film, because the film is developed using James Cameron Fusion Camera-3D System shooting, will the SONY HDC-F950 CineAlta F23 digital cameras and digital camera dual combination. Output resolution digital camera was about 2K, after conversion to 70MM film, the resolution and color, saturation have been enhanced. Digital IMAX version are currently 2K machine (ie, put in a resolution of 2000 images) Dual show. Film format resolution for conversion was approximately 6K, seemingly better than digital formats. "Avatar" Although theories about 2K resolution digital output, but because most of the lenses are CG production, new sources resolution should be higher; present the naked eye is difficult to see the digital version and the conversion of the film version will be a qualitative difference.
 
 And later went to the city of Grand Shanghai 3D cinema read it again, this time deliberately took a look projectors. Is a single projection lens has an inclined front transparent plate, a polarizing plate should be, the film post-production, the two images are alternately printed on the same motion picture film, the film passes through the polarizing plate source projected to the screen , and then through polarized glasses inverse solution, respectively, into the left and right eye image appears 3d lenticular effect.
