Shark Boy & Lava Girl could have been a much better 3D movie, If Rodriguez had hired somebody on the cutting edge of anaglyph digital. Like most studio movie makers he chose to "farm out" the 3D anaglyph effects to people who have never got their feet wet with anaglyph developement. I'll suggest you have to know have to make a good color still in anaglyph before you can get into 24 or 30 frame per second film or video. They never tried to get the glasses to deliver good color, but rather took the linear approach...They opted for MAXIMUM CANCELATION of "wrong view" per eye as the prime objective. That is SO...O..O right with color nuetral polarizers, but SO...O..O WRONG with colored filters!!! PKK is right on when he bemoans the fact that these efx boys haven't , in effect, paid their dues! Anaglyph has major limitations, but you don't have to "de-ball" the color to make the composite work. He made the mistake that PKK has mentioned. He didn't try to control the image off-set by reducing the stereo base below norms that work for POLARIZED release. If you would shoot a polarized scene with a 3.5 inch base, between the camera lenses, you'll do well to shoot the same thing for anaglyph release with perhaps a 2.0 inch base, on the cameras shooting actors. The Green screen should be rendered to a "virtual" offset of less than 1.5 inches. This will pull in the b.g. closer to the actors, when the green screen is integrated with the forgorund (actor) plates. doing it this way keeps the offest with limits that permit fairly good color to be passed by the glasses. All good color anaglyph REQUIRES a slight red cue to tint objects through the cyan lens. Filters that kill all red...SUCK. This is not polarized 3D...GET IT! We have made some very nice NEW high cancellation plastic glasses for 3D movies like "Shark Boy", they are infinitly more comfortable on the eyes and on the face, than the joke glasses offered in the theaters. They actually flatten your eyelashes! Like kids swim goggles. The muted color on "Shark Boy" 3D scenes is bloody awful! The "maxed out" glasses make it even worse. Let's hope this doesn't kill 3D as it tries to be reborn. I | ||

Someone desperately needs to get a really good (I mean "great!) anaglyph movie out there to set the new standard for anaglyph quality. Maybe once large numbers of people "see it", it will force other anaglyph movie-makers to match the quality, and we won't have to suffer through another terrible anaglyph conversion. I hope the damage is not already done, and it's not too late at this point to "save" the situation... that's my biggest fear. It might be like trying to tell people that "Wasabi peanuts can taste like candy if they are prepared properly" :-( The most irritating problem, IMHO, with Shark Boy & Lava Girl was the "dark left lens" problem that makes you feel like you are partially blind in the left eye, which my wife noticed about a minute into the beginning of the anaglyph portion of the movie. She said, "Something is wrong with the glasses. The left lens is too dark." Every time this problem got really bad, which happened way too many times (quite often throughout the entire movie), I took off the glasses and looked at the imagery, and there was an overall "blue" cast to most of the scene. Many blues in the red-cyan anaglyphs create this common "dark left lens" problem, if they are not properly "shade-corrected". I figured out how to correct these blues very early in my anaglyph research days, as the problem is almost as common and irritating as the "reds" problem... many reds turn completely white through the red lens, and many blues turn "dark". Those are actually the two extremes, but many other colors create similar problems... just not always as badly. There are actually quite a few shades of blue that work perfectly, so there is no excuse for the "dark left lens" problem. Coming up with decent looking reds is much more challenging... but possible :-) -- P. K. Kid Stereoscopic 3D images and movie clips (all G-rated): http://www.puppetkites.net | ||

> All good color anaglyph REQUIRES a slight red cue to tint objects through the cyan While it might help to get better color reproduction, this in fact is ghosting. I prefer less gosting and less retinal rivalry over accurate colors. I also dislike the idea of reducing stereo base. The stereo base should be chosen to get realistic depth, not larger and not smaller. Rodriguez's movies are not intended for anaglyph viewing only, but also for polarized projection systems and it would be very costly to create two versions with different stereo base. | ||

I was refraining from seconding Peter's opinion, and had even typed and deleted my post, but now I have to say.. Yes even I would prefer better cancellation over color spectrum in an anaglyph. There is always the option when making an anaglyph movie of 1) Not using Red subjects 2) IF red is necessary, such as a santaclaus outfit or spiderman, then using color correction BEFORE going into anaglyph processing of the video, to a more mutes or subtle shade of red.. like rust color. No sense in having "full Color" glaring red in anaglyphs at the expense of ghosting. BTW the "glare" is also noticable in sky backgrounds if you let red leak thru or keep saturated red in the main film. Regards Clyde |
