For those of you who don’t know what parallax is, it refers to the small differences in the stereo pair images in 3D footage. It is important for stereoscopic enthusiasts to under stand how parallax works. When you look at a particular point in a scene there is a path from each of your eyes to that point in the scene. Now there are three possibilities for what this scenario can look like.
The following image will help to understand parallax:

The blue line represents the screen that you are watching and the red dot represents where you will see a 3D object in relation to the screen. now in reality when you’re watching 3D there is a right image and a left image that lie on the screen and where the red dot actually lies on the screen is represented by the spot where the green lines intersect the blue lines. However when your brain receives this information it tricks you into seeing an object in front, on, or behind the screen–again, represented by the red dots.
A film director has precise control over what elements in a scene have positive parallax and negative parallax; that is what elements appear to the audience in front of or behind the screen. That is where a big debate comes into play. Some suggest that the real thrill of 3D is object flying out at the audience. Others argue objects behind the screen allow viewers to really put themselves in the action and immerse themselves in the story. What’s my take on it? I think I am with most real 3D enthusiasts. I believe that negative parallax, or things flying out of the screen, are more of a novelty. Whereas, positive parallax or creating a world behind the screen is really where the magic of stereoscopy happens. This really lets you immerse yourself in the story and often in a different world as in Avatar or Alice in Wonderland. What’s your take?

So you’re a stereoscopic enthusiast and you’ve read all about different rigs, set-ups, cameras, techniques, and tricks about filming 3D, but you’re wondering what the professionals use. We’ve got your answers here at DepthBeyond. We’ll review some newer live-action 3D movies/productions and discuss the hardware that makes the magic happen.
James Cameron’s Avatar
James Cameron spent 7 years building a perfecting his own 3D rig for Avatar, aptly named the Cameron-Pace 3D rig. Think that’s crazy? He filmed almost the entire movie with the 28 lb rig on his shoulder. Cameron is a huge proponent of the beam splitter rig. He believes the ability to control the interocular in a beam splitter rig is essential to make a good 3D production. This is especially important when cutting between views from long range and close ups so as not to confuse the brain and make the viewer sick. The Cameron-Pace rig is complete with left and right hand triggers that control zoom and focus, a remote controlled interocular shifter, as well as a carefully calibrated built-in PC that makes sure the cameras are perfectly in-sync. Cameron wouldn’t put a price tag on the rig, but from my research I’m guessing it’s between $90,000-$130,000. Talk about a hefty price tag, but I think the results speak for themselves.
My Bloody Valentine 3D
The producers and director of My Bloody Valentine were thinking along the same lines as Cameron when they chose to go with a beam splitter rig as well. Where they differed is the shopped the technology rather than create it themselves… I guess we can’t knock them too much for not spending 7 year perfecting a 3D rig. They went with the ParadiseFX (PFX) system which is one of the most advanced and refined systems being used today. PFX has spent 14 years perfecting the techniques of 3D filming and the art of putting the right hardware in place to get the job done. Take a look for yourself:

ESPN
Okay, I know I said Hollywood, but I had to throw ESPN into the mix, there just aren’t that many live action 3D movies out yet, and who could resist taking a look into what the sports giant is using to put depth onto the gridiron and the diamond. Seems as if they’ve got some beam-splitter rigs as well, built by a man named Vince Pace. Name sound familiar? Maybe it’s because it sounds suspiciously like Vince Chase from Entourage (wrong) or maybe it’s because he’s the same guy who, with Cameron, pioneered Avatar’s Cameron-Pace rig. You’ve got it. Pace put his hard work to helping build similar rigs to the one’s used on Avatar but optimized for the world of sports. Not only do they have beam splitter rigs, they also employ specially designed side-by-side rigs, and remotely controlled rigs that can hove across the field. ESPN has poured millions of dollars into this technology and our putting their money where their mouth is when it comes to 3D.

I bet you think you know who’s gonna grab the top spot on this list, but you’re probably wrong! Some people think that a big budget and the most advanced 3D graphics make a great 3D movie. While this can make for a cool experience, a great 3D movie uses 3D to enhance a truly great story. Here is how I rank the 3D movies… leave a comment, and let us know your thoughts.
#5 Alice in Wonderland

Alice in Wonderland came with a lot of mixed feelings. It was up against being a remake, one of the first live action feature films in the new 3D era, and being subject to Tim Burton’s unique style. On the other hand , it got a lot of buzz and has some major star power from a certain pirate turned mad hatter (Johnny Depp, for those of you who live under a rock). Some people weren’t impressed with the scripting or the 3D effects (many saying they were distracting), Tim Burton and the producers of this movie delved into the 3D live action world with a large stereographic team. Live action 3D is not nearly as easy as animated 3D and it is important for Hollywood to take some shots before they perfect it.
What they got right: They created a visually stunning dream world that really highlighted what 3D can add to a film.
What they got wrong: They had a really hard time working 3D into the script and make it not distracting.
#4 Shrek the Third

The Shrek franchise has held young people captive since its inception. It has bridged age gaps and can be enjoyed by viewers of literally all ages. It also has a simple but powerful message, “beauty is internal.” Shrek is also one of those powerhouse animation films with a top rate voice cast highlighted by Eddie Murphy, Cameron Diaz, and Mike Meyers. Disney has caught some backlash saying that the movie was watered down from previous versions. While this may be true, it is still a great film for young people to enjoy. Finally, Shrek the Third has been heralded by many as one of the best as far as 3D animation. The 3D effects did not get in the way of the story yet enhanced it. The characters and landscape were complex yet refined. Altogether a wonderful viewing experience.
#3 Monsters vs. Aliens

DreamWorks hit the nail on the head with this family friendly 3D adventure. The movie combined some great voice talent (Seth Rogen, Will Arnett, Reese Witherspoon, Stephen Colbert, Kiefer , Sutherland, and Hugh Laurie), as well as stunning 3D animation. This was the backdrop to a script that was exciting, yet age appropriate, with a little slice of sophisticated humor for the older viewer. The 3D in this movie was headed by a long time stereographer Phil McNally. Some of the negative parallax (i.e. things coming out of the screen) that was done in the movie was a little bit cliche, but I guess you have to have some of that in a 3D animation flick. Overall, the stereography was stunning and seamless.
#2 Avatar

Hold the presses, Avatar is not first on the list!?!? Avatar was great! It was amazing. James Cameron created a world unlike any other. The world and the stereography that put us audience members in it was simple terrific… and expensive. I don’t think I need to go into too many detail about the film considering that every person in the developed world has seen Avatar in 3D. They did an amazing job on the film and it is the absolute pinnacle of live action 3D combined combined with animation. The only complaint with this movie was the fact that Avatars plot was incredibly cliche. I’m pretty sure its box office numbers say that still did ok.
#1 Toy Story 3

Toy Story 3 is the perfect 3D movie. It has 3 elements that distinguishes it from the other films on this list. It performed at the highest levels for plot, 3D effects, and the combination of the two. It is not a only a great film despite the 3D effect but it uses beautiful cinematography and stereography that works in seamlessly with the film. The film is an emotional one, guaranteed to produce tears and the stereography allows you toput yourself in the movie and really feel that emotion.
Notable Mention: Kung Fu Panda
Worst 3D Movie: Clash of the Titans

3D TV is a huge step forward for the 3D industry but it still remains to be seen whether it is just a fad or a permanent staple in the living room.
There are many bloggers out there with a wide range of opinions on this. Dissenters will contend that 3D is just a reason for TV manufacturers to hike up TV prices (lots of them thought the same thing about HD). However, I am sure that many of you stereoscopic enthusiasts are excited and are drinking the 3DTV Kool Aid.
I think we can agree that there is more money for the television providers and for some of the networks with 3D TVs but it is doomed to fail if the consumers don’t buy in. The question basically becomes does the average consumer want to watch TV in 3D or don’t they?
This is a question that we just don’t have the answer to yet, but lets think about why they might or might not want to:
Why we Want to Watch TV in 3D:
- Anything that makes the viewing experience better for sports will sell
- 3D movies are hot, and we want to be able to enjoy that experience at home
- 3DTV is new and just plain exciting
- 3D really helps immerse you in what you’re viewing
Why we Might not Watch TV in 3D
- Glasses!
- Expensive!
- We don’t really understand 3D
My opinion is that once consumers are used to seeing things in 3D on a regular basis, adoption of this technology will take off. What can we do, as stereoscopic enthusiasts, to speed up this process? The one thing you can do is educate everyone you know about 3D! This is the best way to speed up the process, so get out there and spread the word!

So virtually everyone is familiar with 3D but lots of people have never heard the word stereoscopy.
Stereoscopy is derived from the word stereopsis. Stereopsis is what occurs in one’s brain in order to be able to see the world in 3D. Essentially each eye gets a slightly different 2D image, sends them to the brain, and the brain fuses the two 2D images together into a 3D image to achieve stereopsis. Stereoscopy refers to artificially presenting each eye with a separate 2D image so that the brain can achieve stereopsis.
Stereoscopy involve 2 steps: Capture and Delivery
Capture involves capturing two 2D images that would be similar to how the way our eyes see the world. There are 3 traditional ways to capture stereoscopic images or what some people call stereopairs (I’ll include more about capture in a later post):
- Side-by-Side Rigs
- Beam-Splitter Rigs
- Dedicated 3D Cameras
Delivery is all about how to you get the images that were filmed for the right eye to the right eye and the images that were filmed for the left eye to the eye. Some of the ways that this is achieved includes color filters, polarized light, and a the new exciting active shutter technology that you see in the new 3DTVs.

Welcome Stereoscopic Enthusiasts,
My name is Seth Baumwell and I love 3D! I wanted to use this first post to introduce you to Depth Beyond and myself.
First about me:
I have been a 3D enthusiast since I was a kid and saw 3D at Walt Disney World. I can remember watching Jim Henson’s Muppet Vision 3D for the first time. It was like nothing I have ever seen. Beyond the impressive “flying objects” I was encapsulated by the world he created in using 3D. Today, with the advancements in technology and the introduction of active shutter, stereoscopic filming is giving creators and consumers even more worlds to apart of. The memories of my youth are still held close and the passion I first felt is burning hotter then ever. I have read everything from Foundations of the Stereoscopic Cinema to 3D Movie Making. I am also constantly following 3D blogs and attend any 3D conferences I can. I am a creator, consumer and an evangelist of everything that is 3D and hope to share and discuss them here.
About Depth Beyond:
Depth Beyond is the premier site for everything you want to know about the 3D industry! I have looked for a well designed website where 3D enthusiasts can learn and discuss about everything stereoscopic, but came up short. Here you can read the latest industry news, write opinion pieces, and interact with each other in the forum. My hope is people who are interested in 3D will learn, share and connect with one another. If you are interested in joining the team, have questions, or just want to say hi, feel free to email me at seth [at] depthbeyond.com
Enjoy the site.
-Seth
