Get your $2 worth of 3-D

With film producers and distributors boiling down the Stereoscopic film equation to the $2 mark-up for a 3-D film ticket, audiences are starting to air their demands for $2 worth of 3-D entertainment...


The following article I wrote can be found in the excellent 3-D publication Veritas et Visus (3rd Dimension edition). I can highly recommend this online magazine for anybody working in the Stereoscopic industry, so do check it out: http://www.veritasetvisus.com/3rd_dimension.htm


...As the average 2009 cinema ticket price in the US is $7.20, that amounts to a mark-up of 22%. So a bit less than a quarter or a bit more than a fifth of the film’s duration should be using engaging, entertaining 3-D to keep the patrons happy. If you charge $2 more for 90 minutes of cinematic entertainment, you are going to have to deliver the extra 20 minutes of 3-Dimensional cherry on top.

When it comes to 3-D, that cherry is more often than not the in-your-face stuff: good old negative parallax, theatre space, the out-of-screen area. One look at the trailer for ‘My Bloody Valentine 3-D’ (2009) and it becomes clear how people equate the term ‘3-D’ with pick-axes flying at the camera and flames engulfing the theatre (even when flames are, in fact, 2D forms). Funnily, the trailer goes straight against the director’s own promotional words of how the 3-D is not used in a cheap and cheesy way like previous 3-D movies! Pretty much all promotional artwork for 3-D feature films throughout cinema history have featured objects jumping out of a cinema screen. It is undeniable that the two or three 3-D shots people remember when they come out of the theatre are almost always negative parallax shots so their importance in the bigger picture of a successful 3-D film experience is immense. That is not to say that a 3-D feature film should consist of an endless bombardment of negative parallax action - ‘Treasure of the Four Crowns’ (1983) is a very good example of what that looks like: throwaway fairground fodder.

So far, storyboarders, designers, directors and cameramen have mostly underestimated the importance and complexity of a good negative parallax shot and underinvested in developing new grammar for this part of the visual language of stereoscopic cinematography. It could be because out-of-screen shots pose an almost impossible challenge for narrative visual storytelling: how can these objects coming out of the screen be used to enhance the story, action and character interaction without engaging with the viewer in first person? So far, only very few 3-D films have managed to have a decent negative parallax shot or two that is not out of place or totally obtrusive. A shot that comes to mind is Jared-Syn’s deadly arm in 'Metalstorm' (1983). The negative parallax in this shot serves a narrative function, is spectacular in slow-motion 3-D and doesn’t take the audience out of the movie. Suspension of disbelief is sustained. But no, it wouldn’t work for longer than the duration of that particular shot and later shots in the movie show the usual stretched arms holding guns, coming out of the screen. Not very intelligent use of out-of-screen space. But then most scenes involving theatre space in 3-D film scripts appear to have been written on the backs of beer coasters, with very childish visuals result.

How would it fly with the audience if an actor of a play started talking to them or even waving a stick at them? And what if the actor were to walk into the audience and talk to the other actors on stage from there? It could be called ‘modern’, perhaps ‘abstract’, but in any case quite odd and probably not helping the flow of the story. It is this dilemma that 3-D film is facing and has always faced: how to make that oddity work in a serious, undamaging way. This is especially relevant as the discussed 22% of the film needs to pay off in the way people remember and love 3-D. And so far nobody has ever said that the deep scenery of a 3-D film has stuck with them for a long time.

3-D eye poking is very much like camera access, camera shakes, on-screen text and other camera-affirming techniques in cinema. It must be approached with the rules to these techniques in mind. The reason for using camera access, interaction with a camera, bumping into the camera, splatter on the camera lens and even showing a camera crew can be for comedic effect, to indicate the camera as a person, to talk directly to the audience in a medieval theatre style or to touch upon a documentary situation for heightened reality and closeness to the action. But with it comes the breaking down of the fourth wall and the illusion – disbelieve is unsuspended.


'Ferris Bueller's Day off' (1986) - constant camera access

A major issue is that the dimensionality easily distracts the viewer from the story and its characters and negative parallax pushes the viewer’s suspension of disbelieve to the limit. More often than not, these shots remind the viewer he is watching a movie and take the viewer out of it completely. The ability to lose one self in the story and character interaction gets dealt a heavy blow by objects sticking out into theatre space. By observing and analysing the negative parallax object, the brain switches sides from creative (left) to analytical observing (right): the worst possible thing that can happen when being told a story. It is especially wry when all a cinema theatre is trying to do is remove cues to the fact one is sitting in a chair watching a movie to enhance the cinema-going experience to its fullest potential. Paradoxically, by getting close to the viewer’s face, the 3-D movie reminds the viewer he is not actually part of the on-screen events. That which makes stereoscopic film great – the ability to get a film closer to the audience – can take away from the very factors that make for cinematic enjoyment.


'Dial M for Murder' (1954) - negative parallax fame

Basically, theatre space can be used a lot without a problem by movies that don’t take themselves too seriously, that are more of a realistic/documentary-style breed, films that are confident enough to use first-person and POV shots or those that are more or less glorified thrill rides. For movies that don’t want to sacrifice their serious nature, subtle negative parallax shots such as the scissors-grabbing shot in ‘Dial M for Murder’ (1954) may just about work, but they can’t fill a fifth of the available screen time with characters reaching into the audience. A solution to the problem may come from a recognition by producers, distributors, theatres and the audience that 3-D movies are a different medium altogether – neither film nor theatre, but volumetric narrative visual entertainment of its own. A new medium with new rules – where the fourth wall can be broken at will and where serious drama is followed by visual puns and an opportunity to examine objects and scenery in volumetric detail. Because an evolution of film won’t happen until old conventions and ideas are abandoned and new ones are fully embraced.

Psychology of 3-D - Memories

Still of Metalstorm 3-D: The Destruction of Jared-Syn
Metalstorm 3-D. The most successful 3-D movie trailer of all time

The success and the future of Stereo 3-D film making depends on a psychological factor: memories. How do we, humans, perceive the world and store our memories? Storytelling is the conjuring up of situations and images in our minds. We identify with the hero of the story and imagine ourselves in his or her shoes as the story is being told. This is equal to the written or spoken word or the visually presented one. So when we see a movie or television program we compare the images presented to the images stored in our memories. And how are these images stored? Flat. Not in 3-Dimensions.

Seeing a 3-D image will put a viewer in the now, in an abstract mode of fight or flee, as this is real life, real danger, real objects right in front of him or her. It does not touch upon our memory banks, recognition or fantasies, as these are all stored and imagined flat. So the experience of stereoscopic 3-D visuals cannot escape the factor of ‘here and now’ and the viewer of 3-D images will not be taken away on a dream cloud of story and fantasy. Instead, he or she will take in the volumetric images ‘as is’. More or less like a circus act.
Think about it: what sticks with you most, thinking back to a recently enjoyed 3-D movie; the moment the hero kissed the girl or the shot where he poked his sword out of the screen, right into your face?

Clever, intelligent use of 3-D can overcome this serious limitation. 3-D film making has to grow up and evolve to escape the primal imagery and primal reaction it manages to conjure up at the moment. 2-D film making has a slight advantage with 100 years of cinematic culture versus a total of about 8 years of 3-D film production (1923/24, ’53/’54, ’83/’84, and 2007/’08). There is some serious catching up to do!

Imax vs. DLP vs. Anaglyph

IMAX3D projection booth

IMAX has provided for a guaranteed way to keep 3-D movies playing for a long period of time, creating more money and more word-of-mouth advertisement for these films and their directors. By creating the process of DMR, films shot of 35MM and HD can be blown up to IMAX size. So this means that a producer looking to generate more money from his film will happily go IMAX and ideally go 3-D. People like James Cameron and George Lucas who can take financial risks are willing to try out this different distribution model and film their next project in 3-D. Indeed, had ‘Aliens of the Deep’ for example not been in 3-D IMAX, it would not have had a very warm welcome in regular cinemas. The upcoming conversion of Star Wars to 3-D will most likely go the IMAX 3-D route, with a detour in the few 3-D enabled DLP cinemas in America. Strangely, the existing and perfectly working 3-D systems of the 1983 craze are not even considered for these releases. If it is the 3-D that counts, Lucas & co should be suggesting these much cheaper and readily available systems to theatres and distributors and not use the films as an excuse to make cinemas purchase or rent 3-D DLP projectors. Or release anaglyphically.

The frantic search for a technical breakthrough in 3-D display, which has been going on for more than 100 years now, is fuelled by the promise of an evolutionary step in visual entertainment. But most of the current audio-visual industry perceives 3-D as a means to re-sell old product in a new shell and moreover, being able to charge more for the same product but with the added 3rd dimension. This statement can be backed up by the observation that there are no real plans to develop a new visual language once the 3-D revolution happens – nobody is being educated or trained in 3-D filming, there is no literature on 3-D cinematography other than technical manuals and even those are mostly unread by the handful of present day 3-D filmmakers.

Recent examples of this failure to do research on the technicalities of 3-D are Robert Rodriguez’ films ‘Spy Kids 3-D’ and ‘The Adventures of Shark Boy & Lava Girl in 3-D’. The wish to display all colours whilst still using anaglyphic glasses is an obvious mistake because reds and blues should not be visible through both lenses. It is very basic knowledge but simply ignored, consciously or unconsciously. There are simple ways to show colours through anaglyphic glasses whilst not destroying the 3-D encoding – not just by omitting reds and blues but by simulating them in the end result as seen through the glasses - but these technologies are sadly ignored and the visually painful experience is used as ammunition for the argument of 3-D DLP projection even though these are two separate issues. And strangely, Rodriguez is in the DLP promoting club, whilst releasing his 3-D films using anaglyphics.

A short refresher on 3-D film history

Chicken Little 3-D
Chicken Little in 3-D by Disney

3-D film, or stereoscopic film, is a peculiar art form. Stereoscopy, the art of displaying images the way we see them with our two eyes - and combining brain - has been around since the renaissance. The moment these visionary painters understood space and the ways eyes see space better, they were experimenting with drawings in stereo. And so 3-D photography has been around as long as regular photography has, yet it has always stood in the shadow of its natural brother. There is no problem at all in placing two lenses next to each other instead of just one, using the same film but splitting the image on the negative in two for left-eye and right-eye image representation. But a device is then needed to view the stereoscopic photograph; a stereo viewer - on which the Viewmaster™ was later based. This necessity of an external viewer has always been an inhibition to a visual art form, which should have overtaken regular photography as the going standard. It never did because the obstacle of the viewing device proved to be too great a one.

Victorian era 3-D photographAfter building the first practical movie camera in history, the Lumiere brothers built a stereoscopic one as well. A lot of their experimental film is actually one of the two reels they normally used to shoot their 3-D. The arrival of a train at la Ciotat (1895) was filmed in 3-D as well as ‘flat’, so the audience did not just run from a train on screen for the first time, they ran for a train approaching them in 3-D for the first time! However much more spectacular 3-D film proved to be over regular film, the necessity of a viewer, now often a pair of anaglyphic red-blue glasses, did again keep it down in terms of popular acceptance.

It is safe to say distributors promoting recent film releases in 3-D are twisting the truth when they claim they have just released the first feature length 3-D film in history because this was done as early as 1922, by an American film called ‘The Power of Love’. The audience would wear 3-D glasses very similar to the modern frame-sequential IMAX glasses, but with the distinct difference of being mechanical rather than electronic to control the shutter closing the left-eye and right-eye side in sequence. Again, distributors and sales people love to proclaim this is all very new technology, painting the brilliant stereoscopic cinematic inventors of a century ago out of the picture.
