3 - D cinema . The first 3 - 500 movie , " The Power of Love , " screen at the Los Angeles Ambassador Hotel in 1922 . To create the 3 - D effect , two cinema were projected at the same time while the audience watched through stereoscope , which looked a lot like the miniature View - Master you might have had as a child .
3 - D movies did n’t reach aggregative appeal until the 1950s , mostly with the cult and horror genres . This is when the white cardboardglasseswith red and blue lenses come into vogue – the technical name is anaglyph . Despite anaglyph glasses ' universal association with 3 - viosterol , they ’re rarely used any longer .
The traditional 3 - five hundred anaglyph glasses apply one violent lens and one blue ( cyan ) lense . Many other color combinations study , too , like red and gullible , but red and blue were used most frequently . The blue lens of the eye filtrate out all the red light , and the red lensfilters out all the blue light , so each eye view a slightly unlike double .
When the 3 - five hundred picture show is projected on the cover , two paradigm are displayed : one in Red River , one in blue angel . Since each lens of the glass has a filter , only one double can strive each eye . The brain unify both visualise together , which results in the illusion of an figure of speech pop or rise off the screen door .
However , using the flushed and blue color combining to get a sensation of depth also causes a degradation of color in the movie . The paradigm quality is a bite fuzzy , and the colour of the 3 - five hundred film always looks a piddling off . The manufacture responded with polarized 3 - D lens to create a better experience for moviegoer .
polarise 3 - five hundred glasses do n’t rely on singly colourise lenses to get the 3 - D effect . They work a lot like anaglyph glasses , though , by flim-flam the Einstein into merge two images into one . polarise lens have a sensationalistic - brown tint rather of red and blue . When brightness level is polarise , all the wave vibrate in one direction . The tv camera externalise one image that polarizes vertically , and another polarizes horizontally . Each lens system only lets through one sort of image , and your psyche commingle each image into one . The final stage result ? Crisp 3 - D images with very little degradation in colour or quality !
3 - cholecalciferol viewing may be shutter specs . you may get these with 3 - D televisions , although the glass run upwardly of $ 100 a set and are price - prohibitory for aggregative audiences . To create the 3 - D effect , TVs do n’t contrive two images ; instead , the actual glasses flip each lens back and forth faster than your eyes can comprehend the move . The 3 - D programme on your TV put across the data to your glasses via infrared technology .
