Talk:Dolby 3D

"the glasses have filters according to the different red, green and blue wavelengths different for each eye"

what the hell does it mean ? !

The screen itself outputs six different wavelengths: two slightly different reds, two slightly different greens, & two slightly different blues. The left eye’s lens filters out red1, green1, blue1, leaving an RGB image. The right eye’s lens filters out red2, green2, blue2, leaving a different RGB image. 121.79.25.242 (talk) 01:51, 8 January 2010 (UTC)[reply]

it does not explain anything ! —Preceding unsigned comment added by 94.75.121.80 (talk) 19:00, 27 December 2009 (UTC)[reply]

"The viewer can also tilt their head and still maintain left/right separation, which is not the case with films using polarized 3D glasses."

This is wrong. Most 3D cinema technologies used today, such as RealD use circularly polarized light which is not effected by the viewing angle.

Classic IMAX still uses linear polarizers. "IMAX Digital" uses Real3D, but sucks for other reasons. Maury Markowitz (talk) 18:29, 18 January 2010 (UTC)[reply]

Tilting the head screws up the stereo effect anyway - just don't do it ! Instead of a 'Left' and 'Right' image you get 'Left-and-up-a-bit' and 'Right-and-down-a-bit' images.--195.137.93.171 (talk) 16:57, 26 December 2012 (UTC)[reply]

color quality and brightness

Unlike polarized lenses, the color quality and brightness is nearly the same as non-stereo projection (i.e.: with no glasses)

Half the light goes to each eye, but half the light is nearly as bright ? A system that uses colour variation gives better color quality than one that is independent of wavelength ? Unbelievable ! Delete ? --87.194.174.252 (talk) 09:28, 15 January 2010 (UTC)[reply]

dolby 3d has normal brightness, see for example here http://www.davidlenihan.com/2009/12/3d_in_theaters.html --Hancoast (talk) 21:42, 25 January 2010 (UTC)[reply]

Standard and circular polarizing systems place neutral-density polarizing filters in front of both the projector lenses and the eyes, thereby dropping the amount of light reflecting off the screen and hitting each eye. Dolby 3D uses optically clear lenses which filter specific color wavelengths without compromising most of the percentage of light that reaches the eyes. It's like the difference between glare-reducing prescription glasses and polarized sunglasses. —Preceding unsigned comment added by 75.83.138.142 (talk) 22:23, 17 May 2010 (UTC)[reply]

Wrong Topic/Title?

Shouldn't most of what is in this article be in the article for Infitec? "Dolby 3D" is merely a US brand, not the official name for the technique. 75.101.123.180 (talk) 07:00, 25 May 2012 (UTC)[reply]

Color wheel

Please note that single-chip DMD (i.e. DLP) or LCoS (i.e. SXRD) projectors with a color wheel do not comply with the DCI standard. Projectors for D-Cinema always use a three-chip light engine without a color wheel. Thus, the wheel for Dolby 3-D only has two sectors, each sector being a band-pass for all three colours (with slightly different bands for each sector. --Fulgura frango (talk) 17:46, 15 September 2014 (UTC)[reply]
