A little bit of Stereoscopic 3D perspective

Toy Story 3D - stereoscopic 3-D
Toy Story 3-D: Something Pixar promised not to do

Toy Story 3-D. Pixar has said in the past that they could not see any reason to release their films in 3-D. When asked personally in 2007, Monsters Inc.'s Peter Docter was clear on the subject by stating: "We have looked at 3-D in the past and have come to the conclusion that there is little to no way in which 3-D can indeed enhance the quality of our storytelling or enhance the character interaction in a meaningful way". And as we all know Pixar is all about stories and character interaction. Lo and behold, Disney purchases Pixar and suddenly the news comes out in 2008: all Pixar movies will, from now on, be released in 3-D. Not only that, but Toy Story 1 and 2 will be re-released in 3-D as well, leading up to the 3-D release of Toy Story 3. So who or what is behind this sudden change of mind? Disney marketing? Why else does the animation studio with the most integrity in the industry change its mind overnight about 3-D, going against their own, strong beliefs about Stereoscopic 3-D film? In PR releases the reason mentioned is digital 3-D projection because, in some people's minds, projection equals story.

Don't worry. Fun to see an actual 3-D PR still, though, no?


Jon Shapiro, producer of U23D:
"3-D has been a gimmick in the past that has been used to fend of radio and then television, but now with digital technology we can shoot perfect 3-D to the pixel."

So how does shooting digital not make 3-D a gimmick, exactly? Because now you are shooting out-of-screen effects with digital cameras? What a strange argument... 'Spy Kids', 'Sharkboy & Lavagirl' and 'Ghosts of the Abyss' are, with all due respect, the living proof of why HD filming does not necessarily equal good 3-D. And why would it? HD is a recording format, not an artistic quality assurance. In fact, shooting HD with it's real-time playback ability appears to hurt a good 3-D end result as directors don't need to visualize shots in their head any more, but tinker and tweak on the spot. A shoot on a Monday morning will thus result in different 3-D camera parameters than one done on a Friday afternoon - as the crew will have different visual tolerances on the different days.

James Cameron:
"Even in its crude form when it (3-D) first debuted in 1951, 3-D cinema demonstrated the power to captivate audiences. However, inadequacies in camera and projector technology resulted in eyestrain and other viewing hardships that quickly killed the medium."

Cameron's 3-D response to those 'inadequate' 3-D movies? Shoot a 3-D film with 1080p cameras, with an interocular of 70mm and converge on subjects 1m away from the camera, while being underwater with deep, deep scenes, with dirt floating at 1mm distance in front of the lens. Then blow this material up to IMAX size and call it the future of 3-D. You mentioned eyestrain and viewing hardship? It's not the recording method that matters, it's using the medium to shoot pleasant 3-D and tell interesting stories. Why is the argument of gripping narrative and cinematic quality confused with projection quality? Because that's one of the very few elements that has changed dramatically over 55 years since Hollywood gave us 'Creature from the Black Lagoon' and 'Radar Men from the Moon' in 3-D.

Convergence, as used in the Fusion 3-D camera rig, is bad for 3-D

So are we seeing a real 3-D revolution? And are there other reasons for the historic failure of 3-D rather than just misaligned projectors? Time for a little reality check:

The real 3-D revolution happened in 1953. There are no two ways about it. The camera and projection systems may now be called ‘inadequate’, but Hollywood had switched over to 3-D in a very real way. The amount of 3-D film released in 1953 and ’54 was not only larger in absolute umber by a factor of 10, compared to the amount of ‘regular’ 2-D films released in ‘53 and ’54, the percentage of 3-D films released and to be released in 2008 is also 10x less than the percentage in ’53 – ’54. So what is going on here? Is it a good old American cover-up of historical facts to the benefit of promotion of new technologies and new product? It is impossible to compare 1950’s 3-D movies to stereoscopic films of today because both eras produce(d) very different cinematic end products. 'The Creature from the Black Lagoon' may not make you scream in terror today, but back in 1953 it was pretty darn impressive stuff. So how can you call those 3-D films ‘cheap’, ‘naff’ or ‘inadequate’? As said, it is the cinematographic use of 3-D that should dictate the judgement of the stereoscopic entertainment, and if you do insist on focussing on the storylines and rubber suits, take a very close second look at today’s 3-D releases because what exactly are the stories being told in 3-D today? Exactly: horror, fantasy and spectacle films. It’s still a big House of Wax here!

LinkedIn Stereoscopic 3-D Professionals Worldwide Group

Recently, I have started the 3-D Stereoscopic Professionals Worldwide LinkedIn Group: a group for professionals working in the field of stereo 3D, who also happen to be on LinkedIn. The group is growing very rapidly and already includes members from the big 3-D producers such as 3-Disney, 3-Dreamworks, 3-Digital Domain (sorry, can’t help it) and Sony Pictures Imageworks.

In the first round-e-mail I sent out, I asked the members why there is not more communication and cooperation between 3-D stereoscopic professionals and, more over, why there is no openness of information and a sharing of industry practises. It seems to me like a logical question and the desire to make the industry benefit as a whole by sharing information appears, on the surface, to be the only way to truly build a global 3-D industry. The immediate answers to this question were very positive and most group members responding agreed with my standpoint of cooperation rather than secrecy and greed towards 3-D information.

Shhh, don't tell anyone: it's a 3-D camera system!

It was not all calls to arms, though, and a little reminder about the reality of the 3-D industry was given by Disney’s top 3-D man: “Unfortunately, I know a lot of 3-D gurus who have been severely punished for their generosity”.

I get contacted almost daily by people who ask for 3-D advice and I am the last person to send them away with no information, as I strongly believe in helping out those who cannot find any information out there and are unable to pay for professional help. How else can a real independent 3-D film library come into existence? But sadly it is not only people unable to pay for professional help who try to get as much 3-D information out of me as possible before they disappear into the thin air... On the upside one can sometimes get rewarded with kind words about supplying free 3-D information and of course a fantastic end product to enjoy. Last year I was contacted by a small independent animation production outset with the words: "I just found your website & I must say I really appreciate all the information you have provided on stereoscopy. I'm doing some research for a 3D film project and this just about answered all of my questions. I do have one more question though.”, and: "There seems to be little information on the world of 3D cinematography on the Internet, with the exception of your website, which has been an incredible resource. Thanks for all your help.”

The metioned question pertained to how small an interaxial should be on a model shoot where the models would be integrated with bluescreened actors and what cameras should be used etc. The company was called Encyclopedia Pictura and half a year after the kind words and my free advice the news of Björk’s latest music video being released in 3-D reached me. Wonderful work by EP and nice & calm 3-D that never goes negative on the parallax but keeps the video in the small theatre of positive parallax, just the way Bjork loves it.

Staying with indie 3-D animation, I have done very brief consulting on an independent stereoscopic animation production in the Netherlands by the name of ‘The 3-D Machine’ and the production company Ka-ching Cartoons thanked me and sent me a complimentary DVD of the final product. If you’re going to take free 3-D advice, at least thank the Stereographer. I am of the opinion that the 3-D industry can only grow when information is shared, but not even mentioning the person who helped you accomplish great 3-D is not the way to work either. That only makes for 3-D professionals shutting their mouths again and keeping the stereoscopic information to themselves in the most paranoid way possible. Regardless I am still keeping my website open for business and the information keeps on flowing freely. Maybe stupidly, but that’s 3-D belief for you.
