Getting close to the edge?

---

'Edge Violation – A visual artifact that can arise when part of an object near the edge of the display is represented in the left-eye image but is not represented in the right-eye image or vice versa.' So says the 3D glossary given by 3D@Home. Figure 1 shows an example of edge violation. A street lamp post is located on the extreme right in the for...

Back to Basics with Stereo 3D

---

In 2011 more than 35 networks in Europe and North America will broadcast stereo 3D programming — and several will launch dedicated 3D channels. 40 3D features are expected to hit theatres this year, and stereo-3D-ready consumer devices from TVs to video cameras to smartphones are hitting the streets. The demand for compelling content to meet the ne...

Glasses wars again

---

It was never going to be easy. Even now, over four years into the modern 3D era, reliably creating and displaying 3D still presents many challenges. Everyone says that the footage must be technically ‘good’ and, for television, the need for glasses is an issue for viewers, though glasses are pretty well accepted for cinema. The good news is that hu...

Doing 3D by the book

---

'3D TV and 3D Cinema: Tools and Processes for Creative Stereoscopy' (ISBN: 978-0-240-81461-2) is Bernard Mendiburu’s latest book, published this summer by Focal Press. It follows on from his previous success ('3D Movie Making') which has had several reprints to keep up with demand. Since the first book came out two years ago, the art of 3D media, t...

3D a Geographic Thing

---

It may just be coincidence but, in the last week, two stories about 3D in Scandinavia have landed on the 3D Diaries desk. Of course two swallows do not a summer make but maybe there is a trend here, with some nations embracing the third dimension more than others. Sony Professional is currently building what they claim is Scandinavia’s first 3D-rea...

Keeping both eyes on the ball

---

It goes without saying that spectator sports are made for television; of course they are, as can easily be proved by trying to follow a football match on radio. A skilled radio commentator can describe key aspects of the action fairly well but television actually gives viewers the impression that they are sitting in the stadium. Widescreen high def...

Game, Set and Match

---

It was only three months ago that this column hailed featured the new DVB-3DTV standard. But already there’s talk of a second version, or rather ‘phase’, as described by David Wood of the EBU in the new 3D Roundabout newsletter. In a way this is healthy. It shows just how fast 3DTV is moving and, whereas phase 1 is designed to work with existing 2D...

The Space Race

---

You would have thought that the Royal Wedding, with its forecast record global viewing, would be available in 3D. Reports in the Guardian newspaper say that Sky 3D was keen to provide a complete 3D service, and indeed they did have cameras to shoot the outside scenes but access inside the Abby was denied. The paper also reports reasons given as ‘ca...

On the level

---

In shooting 3D you naturally have two cameras and two lenses: albeit, there are some weird and wonderful single lens/single sensor contraptions out there. This usually means there are any number of ways each camera lens combination could be producing images with minor are major signal level differences. If these level differences are not dealt with...

3D or not 3D, that is the question

Peter Savage wonders if the buzz around 3D is really justified – despite his willingness to don some 3D specs and head to the big screen in his local pubLast Saturday night I sat and pondered the broadcast question of the moment – 3D or not 3D?Not unlike poor Hamlet, unable to reconcile his mind on life, I was torn between the hype and the reality...

3D One year on

---

The month started with a trip to Sony to visit its very impressive 3D Customer Experience Centre where Paul Cameron (Training) gave a three-hour run down all about 3DTV production. This very compact version of Sony’s three-day course kept me on my toes. Early on he pointed out that 3D had been in favour, and then out, several times already, at abou...

A little bit over the top

---

Vertical disparities in 3D stereoscopic images have several causes: principally they would be due to one camera being mounted such that its optical axis is higher than the other. Effectively, one eye could be seeing more over the top of objects than the other. The vertical registration is impaired and will cause headaches for any viewers as their e...

Its a MADI World

---

At this year’s NAB Show in Las Vegas, 3D solutions were still a hot topic — but one emerging technology threatened to steal the show. In fact, the rapid growth of devices that support the Multichannel Audio Digital Interface (MADI) has more potential for simplifying broadcasting operations than perhaps anything else. But what exactly is MADI and wh...

3D Post at NAB, Wimbledon, and more

---

You may recall that last time 3D Diaries tackled the subject of post production in August 2010, it warned that the ‘fix it in post’ habit was definitely to be avoided. This means shoot it correctly in the first place, as trying to fix errors, especially the 3D ones, in post can get very tricky and, may be expensive. This remains the case even thoug...
