That Amazing Drone Video and The New York Times

An absolutely beautiful piece of video went viral - the stunning drone footage of Bryant Lake Bowl & Theater shot by Jay Christensen is wonderful and has been showered with praise on social media.

In visual effects, we constantly bump up against an uncanny valley of sorts when it comes to camera moves. Over the decades, audiences have become completely aware of dolly camera moves, tracking shots, steadicam, hand-held, big booming crane shots, and have integrated these moves (either consciously or unconsciously) into their cinematic vocabulary. These types of camera moves "make sense" to audiences, and therefore "feel honest". Sometimes, artists and directors who create live-action scenes rendered entirely in computer graphics go too far with their camera moves (twisting, twirling, speeding up and slowing down with magical precision), creating camera paths that are literally unachievable in the real world, forcing audiences to consciously or unconsciously reject them as "dishonest". We sometimes refer to unrealistic synthetic camera moves as "cameras of God", as in God is the only camera operator who could achieve this kind of move.

When new camera techniques become ubiquitous, audiences will accept them as "honest" and consider it part of the vocabulary.

 

That's what I was trying to get across in my hastily written tweet - that this drone shot, captured in-camera, could signify the addition of these types of authentic live-action camera moves into our cinematic vernacular.

I was very surprised to see The New York Times' writeup of the drone shot and its reaction from Hollywood filmmakers.



Wait - "adds to the language and vocabulary of cinema"? That sounds familiar. Sure enough, after quoting praise from Lee Unkrich, Elijah Wood and James Gunn, they quoted my tweet.


I'm thrilled that the video is getting such praise, and am humbled that The New York Times thought my comment was of any interest.

The Dolly Zoom in "Ratatouille"

The subtle dolly zoom in "Ratatouille". Scroll down for a large, annotated film clip.

Vashi Nedomansky has edited a brilliant 8 1/2 minute montage called "Evolution of the Dolly Zoom", which is a big hit on the internets. Thankfully, Nedomansky did not feel the need to add every single dolly zoom used in the history of cinema, especially since the 1990's the trick shot technique has long since turned into a visual cliche -- a crutch to crudely jackhammer an emotional reaction from the audience. Nedomansky's montage flows extremely well, especially with his soundtrack choice: Bernard Herrmann's haunting music from "Vertigo".

My first exposure to the dolly zoom was Steven Spielberg's "Jaws". I nearly burned out my VHS copy of the film, rewinding its dolly zoom shot over and over again to study the effect. Many years later I saw Alfred Hitchcock's "Vertigo", which many regard as the origin of the technique in popular cinema.

To sum up the effect of a dolly zoom: the camera moves closer to a subject while at the same time zooming out its field of view. The effect could also be achieved in reverse: the camera dollies away from the subject while zooming in its field of view. The effect is jarring - the world seems to become a foldable accordion; we rarely see these two processes happening at the same time in cinema. One can dive deeper into the mechanics of the dolly zoom here.


The camera move is most often used by directors who want to visually punctuate a dramatic emotional turn; a character's world is being turned upside down, and their relationship with the world has dramatically changed in a single moment. In "Jaws", Spielberg used it at the precise moment Chief Brody's deepest fears came true, as he witnesses a brutal shark attack at the beach. (For "Jaws", Spielberg began the shot with a long lens and the camera far away, then dollied close to Roy Scheider while zooming out.) In "Quiz Show" director Robert Redford applies the technique as Charles Van Doren takes his first step into a world of deceit and fraud inside the game show booth, betraying his values by cheating on a television game show.

In contrast, in"Goodfellas" Martin Scorsese uses the technique to illustrate Henry Hill's increasing pressure and paranoia.. Hill meets with Jimmy Conway, but is fearful that Conway is setting him up for a fall. As they sit down at a restaurant for their discussion, tension fills the screen as the background dramatically increases in size while Conway and Hill remain consistent, visually mirroring the intense, increasing stress these characters are under. (For "Goodfellas", Scorsese does the opposite of Spielberg's "Jaws" example: he begins the shot with the camera close to the actors, slowly dollies backwards while zooming in during the move, collapsing visual depth during the shot.)

Evolution of the Dolly Zoom by Vashi Nedomansky

And, most dramatically, its use in Tobe Hooper's "Poltergeist" is terrifying. Simulating the awful dream-like feeling of running without getting anywhere, with your goal receding into the distance, Hooper (and Spielberg) designed a shot where Diane Freeling, desperately running down a hallway to rescue her children from ghosts, sees her children's bedroom drift into the distance, putting them out of reach. It's a truly nightmarish sequence, visually portraying a loss of control.


In his video edit, Nedomansky also smartly includes context for these dolly zoom moments, rather than simply creating a supercut of dolly zooms cut together. This way, students of film can catch a glimpse of the surrounding shots, giving a bit of context as to how and why the dolly zoom was used by the filmmaker.

However, not included in Nedomansky's cut is the subtle dolly zoom in Brad Bird's "Ratatouille", one of my favorite uses of the technique in the last decade.

Why do I find this use of the dolly zoom in "Ratatouille" so brilliant?  For one, most audiences did not even consciously realize the effect was occurring because a critical piece of the emotional core of the film was being delivered to the audience. In the shot, the camera is focused on the television in the background, giving the audience important information about Remy's culinary hero, Chef Gusteau. The chef gives our hero an inspirational speech across space and time (through the television), and reminds Remy of the all-important notion that "Anyone can cook, but only the fearless can be great." The shot begins with a conventional move; the camera dollies towards Remy, with the television in focus. In the middle of the shot, the camera slows to a stop, and begins to dolly backward just as a zoom-in begins. Remy remains the same size in screen space, but the television screen blows up dramatically. A lovely feature of this effect is not only the collapsing depth (which focuses our attention), but also the ever decreasing depth of field. Remy becomes more out of focus as the shot progresses (since the focal length is getting larger), which is exactly what would happen with real-life camera systems.

(I've written about "Ratatouille" and its thoughtful camera work before; if you're interested, click here and scroll down for other "Ratatouille" articles.)

Director Bird could have simply dollied in toward the television as Gusteau gives his speech, but he chose to execute a dolly zoom. The scene lays groundwork for the emotional themes of the film. The dolly zoom underscores this important, emotional moment.

The effect is used in "Ratatouille" with confidence and elegant subtlety; like previously stated, most viewers do not even realize the perspective is flattening out*, which is antithetical to the modern, in-your-face cliche use of the dolly zoom. The technique is generally used as punctuation (usually an exclamation point), screaming "The characters are going through something significant RIGHT NOW!" In this scene from "Ratatouille", the dolly zoom is simply part of the mise-en-scène  and not the focus of the shot. Like the editing, costumes, and the lighting, the dolly zoom is not meant to be seen, but felt.

Although the effect has been done in animated projects before, it is extremely rare to see the technique outside of live-action. Pulling off a flawless dolly zoom in live-action takes repeated rehearsals and intense, precision choreography between the camera operator, camera assistant, grips and actors.  The zoom and dolly need to ramp in and out of their curves with grace, and requires the crew to execute the move with nearly a hive-mind. (Just look at all those dolly zooms in Sam Raimi's "The Quick and The Dead" in Nedomansky's supercut. For the most part, the initial starts and ultimate ends of the moves are left on the cutting room floor, but the shots add an additional variable - the animated dutch angle, where the camera rolls during the dolly zoom. Just the thought of the intense choreography that was required to pull off those complicated moves makes my head spin.)

In computer animation, the intense precision required to pull off a flawless dolly zoom in live-action is greatly simplified with curve editors plotted on a computer screen. In the digital realm, where pretty much any camera move is possible, the filmmaker is allowed to express himself with precision nearly impossible within the confines of the real world.

The bonus, super-quick dolly zoom from Ego's bite of Remy's food. For the animated GIF above, I've edited out the flashback, retaining only the start and end of the flashback, which reveals the extremely subtle dolly zoom effect.  As a bonus, notice how the lighting on Ego's face is neutral/cool before the flashback, but after the flashback he's bathed in a warmer light on his face, visually underlining his new, warmer perspective.

In fact, Bird sneaked an additional dolly zoom into "Ratatouille", albeit a brief one. In the film's single most dramatic and memorable shot, Anton Ego's first taste of Remy's ratatouille dish throws him into a childhood flashback. The first frames of that flashback, depicted as an extremely fast whoosh with the camera traveling backwards in space (and time), settling on a young Anton Ego at his childhood doorstep, begins with a smash dolly backwards that actually ends up moving through young Ego's pupil and settling on the final composition. The flashback whooshes away, revealing the present, and the camera inverts the action with the reverse of the initial dolly zoom. The effect is disorienting and barely visible, introducing this radical and unexpected flashback, and ultimately enhances the emotional impact of the brilliant shot.

*Before publishing this article, a Google search for "dolly zoom Ratatouille" came up with zero results discussing the Gusteau dolly zoom, which I found quite remarkable.

Films Every Visual Effects Artist Should Watch: "Baraka"

This is the first of a series of articles, titled "Films Every Visual Effects Artist Should Watch."

I have written many times about the need for visual effects artists to watch movies, particularly non-visual effects films. For those of us working in the realm of photorealistic visual effects, that is, visual effects whose goal is to blend into the world of the live-action film, it is essential for us to keep our eyes on the target of our efforts. Our target is photorealism - scenarios and characters that, ostensibly, have been photographed right alongside our actors on soundstages and on location, that help tell the filmmakers' stories. In this respect, I encourage young visual effects artists and seasoned artists alike to watch, break down and analyze non-visual effects films. Understanding what is photorealistic will help artists create photorealistic images. This ability is especially important for those in the disciplines of, but not limited to, model making (both CG and practical), texture painters, lighters, and compositors.

Watching and analyzing non-visual effects films will give artists the visual vocabulary of photorealism, and gives the artist the ability to answer questions like, "What makes this look real? What are the visual cues that force the audience to believe that character is standing there? What are the shadows doing in this shot?" One does not need to ask "Why" questions, as in "Why is that portion of the frame overexposed?" One needs to be more concerned with "What" questions.

A mastery of the visual cues that trigger our impulse to "believe in" an image is the single strongest tool in a visual effects artists' toolbox. And this is why every visual effects artist should watch Ron Fricke's "Baraka."

Created in 1992, "Baraka" contains moments of spectacular beauty and intimate humanity, both on an epic scale and in miniature proportions. And there are no visual effects in the film, which makes it a terrific candidate for visual analysis.

It's not a travelogue, nor a vanilla, large-format nature documentary. The film is an exploration of what it means to be a human being on this planet. Or not. One of the beautiful aspects of this dialogue-free film is its seemingly limitless expanse of interpretation. Ten people could watch this film and emerge with ten completely distinguishable interpretations of its meaning, or its central theme.

One thing is certain: the photography in "Baraka" is breathtaking. Photographed by Fricke in a 65mm film format, largely with available light with relatively fast setups in difficult locations with a tiny crew (usually three people, including Fricke), the shots in "Baraka" are stunning. The camera is largely sedentary (with long, lingering lockoffs, peppered with deliberate dolly moves), which allows the imagery to speak for itself. Fricke is an extraordinary cinematographer, and "Baraka" is his crowning achievement as a cameraman. (As an aside, I had the unique privledge of compositing some of Fricke's photography; for "Star Wars: Episode III," it was Fricke and his team who photographed the real lava blasts on Mt. Aetna in Italy, which we ultimately used as elements in the Mustafar sequences for the film.)

Much has been written about "Baraka," so I will excerpt from a far-superior writer to get his take on the film. From Roger Ebert, who recently revisited "Baraka," crowning it one of his "Great Movies":

The film consists of awesome sights, joyful, sad, always in their own way beautiful. By that I do not mean picturesque. A friend came into the room while I was watching the film, saw a closeup of the head of a Gila monster and said, "That's beautiful." I asked if she liked lizards. "I hate lizards," she said, shuddering. She wasn't thinking about lizards. She was observing the iridescent scales of the creature's head... Tiny bright plumes in a desert are revealed as the burning oil fields of Kuwait. Mothballed B-52 bombers reach to the horizon. Manhattan. Corpses are burned on the banks of the Ganges. Will they know the donkeys are pulling a cart much too heavy for them? They will probably understand mountains, waterfalls, volcanoes. Do we? "Baraka" is paced so we can contemplate the places we will never go, the places we are destroying, the places where we might find renewal. It is like a prayer.

Like Ebert writes, the deliberate pace of the film allows the viewer to not only absorb the images, but to contemplate their meaning. And this deliberate pace gives us an opportunity to study the imagery in unique ways.

Specifically, there are several things effects artists can take away from the film. For one, "Baraka" allows effects artists to see how scale is represented, both large and small. Notice the visual cues that the shots of Ayers Rock in Australia are giving the audience. How does this look different than, say, a one-foot dirt pile in the road?

The slow moving dolly shots allow artists to analyze the effects of parallax. When working within a 3D system, most of these technical decisions are made for you automatically. However, if you're designing a world, and are trying to convey a feeling of vastness, how you build the scale of your scene will dramatically affect the way it is interpreted by the audience if you are unaware of the power of parallax. (A lack of understanding can sometimes lead to visual effects shots where elements are placed in space in such a way that, when the camera moves, the audience feels like they're viewing billboards on cards of varying scale, rather than real-life objects placed realistically within a world.)

One of the many deliberate, slow dolly shots in "Baraka," featuring skulls from one of the killing fields in Cambodia.

There are several shots in the film that feature group behavior, which is perfect for analysis for anyone who is tasked with creating synthetic crowd shots, either human or animal. Watch the poetic precision of Amazonian men dancing crosslegged, or the swirl of men walking around the Kaaba cube in Mecca, or the seated factory workers creating cigarettes in rows as far as the eye can see. For anyone who has to create crowd behavior, there is much to examine here.

And for those who create synthetic environments, there is plenty to examine. Modern cityscapes, both crisp and new, and dilapidated and pathetic. Ancient ruins, religious temples, places of intense historical horror, and locales of deep spiritual significance. Also represented are elements of the earth; water, wind, sky and stars.


Although there are no optical tricks used in "Baraka" to enhance the film, one technological technique used to create certain shots involves a giant step in the evolution of time lapse photography. Several shots in the film feature extreme speed changes, both slow motion (running the film camera at a higher frame rate), and fast motion (running the film at a slower frame rate). Traditionally, these shots are from a locked off camera with a single exposure, which freezes the point of view. It's the time-lapse with which our eyes are quite familiar. The filmmakers behind "Baraka" added an additional element to their time lapse (fast motion) shots: a moving camera.

Using motion control dolly systems, the cinematographer was able to program a dolly/pan/tilt move on their time-lapse shots, which creates a unique viewing experience. The process is very much the inverse of so-called 'Bullet Time,' which features elaborate camera moves on slow motion shots. The "Baraka" team also had the capability to program exposure changes into their timelapse shots, which means they could photograph a single take that occurs over several hours and compensate for massive changes in light. This is especially important for the day-to-night time-lapse shots, such as the big city dolly into traffic, or the film's climax which features several moving camera time-lapse shots of canyons at night with starfields and clouds zipping past mountains.

In this amazing time-lapse shot, the camera slowly dollys forward through an open window to reveal the living, breathing city, just as the sun sets. The rhythmic pulsing of the synchronized street lights, along with the subtle soundtrack, imparts an ironic sense of organic life amidst a sea of concrete and steel. This motion control time-lapse shot is one of the most memorable scenes in the film.

"Baraka" also has fun with its editing style, frequently cross cutting between two very disparate scenarios, allowing the viewer to interpret its significance. In one of the showcase montages of the film, Fricke cross cuts between baby chicks placed on conveyor belts in preparation for their lives as egg hens, and various time-lapse shots of commuters around the world. This narration-less juxtaposition of images allows the viewer to interpret a message (if one exists), rather than having it spelled out by the artist.

Consistently, the photography of "Baraka" is honest and true. It provides a gold mine of inspiration for modern visual effects artists whose job it is to create honest and true images, both in the grand scheme and in specific terms.

Even though "Baraka" is a small, special-interest film that is over 15 years old, its following is strong. 70mm prints of the film show up at 70mm film festivals in big cities all the time. (Take a peek at this schedule from in70mm.com, which shows upcoming 70mm screenings from all around the world, and notice all of the "Baraka" listings.) I've personally seen it projected in 70mm in Chicago, Los Angeles and San Francisco. And the DVD of the film looks pretty darn good, as well. But for those of you with Blu-ray players, you're in for a special treat.

Recently, the film was painstakingly restored for future generations, creating a stunning new video transfer which is now available on Blu-ray. Ebert wrote, "The restored 2008 Blu-ray is the finest video disc I have ever viewed or ever imagined. It was made from the Todd-AO print, which was digitally restored to a perfection arguably superior to the original film... 'Baraka' by itself is sufficient reason to acquire a Blu-ray player."

The Digital Bits wrote: "Quite simply, Baraka is the best looking live action Blu-ray release I have EVER seen. It's truly an extraordinary viewing experience... astonishing. [The] Blu-ray release of 'Baraka' is a landmark achievement for the format."


Over the years, I have been hesitant to toss a DVD of "Baraka" in front of someone who had never seen the film before, thinking that I would be giving them an abstract approximation of the film by showing them a crippled, low-resolution version of the film. And although the DVD is worth viewing, it cannot remotely get close to the experience of viewing this beautiful film in 70mm on a huge screen. In fact, I considered embedding video clips into this article, but ultimately decided against it for this same reason. However, with the superlatives being thrown around concerning the quality of the Blu-ray release, I can confidently recommend a home video option for viewing this exceptional film.

These last three shots, scenes from the Ganges river in India, are ripe for visual analysis. In the middle image of the harbor, for example, notice how the atmosphere builds up over the depth of the shot, how the foreground boats have a richness of contrast, while the background boats and buildings appear contaminated with atmosphere. The lens is not particularly wide, but the sense of depth is palpable. The lower image, of bodies being cremated at the river's edge, is richly composed. We have areas of direct sunlight and shadow, various levels of smoke and fire, atmosphere that is patchy yet discernable, and people moving in and out of all of these elements. Visual effects artists are frequently tasked with creating these scenarios completely from scratch. If one analyzes rich, deep, authentic real-life shots like these, one will have a stronger toolset of techniques to help create realistic, plausible effects scenes.
