BBC on 3d TV
Sorry for the lazy post - but I have been up to my eyes in prepping for
the Unconference for EverythingFuture.org.
I will get some more real life stuff down soon...In the meantime.

Quality warnings issued over 3DTV
Technology reporter, BBC News
Hollywood epic Clash of the Titans was painstakingly converted into 3D frame-by-frame but the image quality received mixed reviews. After years of trial and error, 3D finally hit the mainstream; at least as far as Hollywood was concerned.
Big box office hits like Toy Story 3, Avatar and Clash of the Titans suggest that cinema goers have an appetite for 3D and they're willing to pay a premium for it.
Now the TV industry is trying to catch up.
3DTV sets went on sale in UK department stores earlier this year, after sports network ESPN committed to broadcasting at least 25 of the World Cup games in 3D.
Despite poor first month sales figures - just 25,000 3DTV sets sold across Europe according to analysts GfK - industry pundits say 3D television is here to stay.
"3DTV is not going to have the same impact as the introduction of colour TV," declared Simon Murray, principal media analyst at Informa Telecoms & Media in a recent report.
"However, it is not a fad and it will prosper as a niche product," he added.
The average TV production has neither the time or the budget of a blockbuster movie. Filming in 3D requires both in large amounts, so the alternative is to film in traditional 2D and then convert it afterwards.
There are various ways of doing this.
All Samsung 3DTV's now come with TriDef as standard. If money is no object, then a proprietry post-production software system - developed by large 3D production houses - is the way many film studios are heading.
One firm, Prime Focus, converted Clash of the Titans into 3D for Warner Brothers in less than eight weeks. It was an expensive, labour intensive process, involving almost 1500 staff said the firm, and the results received mixed reviews.
Budget 3D
But there is one option that has no financial cost.
TV manufacturer Samsung recently announced that it will be including automatic conversion software - TriDef, developed by DDD - in all of its new 3DTV sets, enabling viewers to instantly "upscale" standard live television into a 3D experience at the push of a button.
TriDef is already embedded in Samsung mobile handsets and Acer laptops.
This type of software has alarmed the film industry, with claims that the automated result is inferior to filming with specialist 3D cameras or using an expensive post-production process.
At a conference in May, Hollwood film director James Cameron - the man behind the animated 3D epic Avatar - warned the result of cheap conversion were "eye strain and headaches".
Panasonic refused to include the software in its 3D sets over quality concerns.
"'We don't think it's right to confuse consumers this early on with second-rate conversion technology,' Fabrice Estornel, product manager at Panasonic TV, told website Home Cinema Choice (HCC).
Chris Yewdall, chief executive of DDD, said the company is not trying to compete with big budget solutions.
"3D is just like any other market - you have good, better and best," he told BBC News.
"We offer a very specific feature aimed at the consumer to get them comfortable with the fact that it is possible to watch 3D at home. There's a cost and quality level associated with that."
Comparing the product with surround sound, Mr Yewdall added that the DDD solution offers an unlimited amount of content as any live TV programme can be split into 3D without adding time and expense to the production cycle.
"When you look at Clash of the Titans , it had a very aggressive schedule and cost of several million dollars. The average consumer doesn't have that. You just want it to work at the press of a button," added Mr Yewdall.

BBC 3d plans for 2012 Olympics
Found this article.
Quite interesting.
The BBC is lining up boxing and gynmastics as its lead sports for a 2012 Olympics showcasing 3D and Super HD TV.
But the corporation is unlikely to launch a dedicated 3D channel for the Olympics – using live venues and ‘red button’ event streams to air the coverage.
Sports with a sense of depth and confined space are expected to make the most impact in 3D, but major field games will also be captured to ensure the BBC has an archive packed with 3D and Super HD.
“The compact space of a boxing ring gives a real wow factor,” Roger Mosey, the BBC’s director of London 2012, told trade paper Broadcast.
“And with gymnastics, if you think about someone doing a vault, they start a long way away and move towards you – there is a real sense of depth.
“Team games and big pictures don’t really work – corner shots in football are good but often the players look like little models running across the field.”
International broadcasters are set to give their requirements for 3D, Super HD and other feeds to the Olympic Games’ official broadcaster, OBSL, this summer.

Liverpool University Psychology Dept. and Vision Lab. trains 3d director in Stereography. Industry Insight Event planned in Manchester on Friday 18th
Courtesy of knowledge transfer funding from the North West Development Agency, Rob Black and Dr Bernard Harper have recently collaborated with RDA Innovation Award winner - Reg Sanders, classically trained (drama on single camera) ex-BBC director who has worked for among others BBC America, Discovery and the BBC.
Recently he began a project called Shoot3D.
The goal is to provide training and equipment for TV producers and directors wishing to capture 3D content for cinema, advertising and television.
Using their research in the Vision Laboratory in the School of Psychology as a base, Rob Black and Dr Bernard Harper provided media training tailored to the requirements of the client. This included distilling widely published research on human perception with studies conducted for the Independent Television Commission in Liverpool.
The data from a series of ITC funded experiments on Cyclopean Vision and
Orthostereoscopic Imaging from Presence journal and conference proceedings *
were the main resource used to guide the teaching and training. Over the
course of the stereographic training, the Reg was equipped with a solid grounding in the processes underlying visual perception. By greater understanding of how the
human brain processes visual information, stereographers are able to modify their
shooting and production grammar to produce more naturalistic and satisfying
3D content.
Much of the 3D media published at the moment is shot without knowledge of
basic principles, and as a result can produce easily avoidable perceptual
problems The key issues that have recurred throughout the history of 3D
imaging have been eyestrain and nausea often coupled to misperceptions of
size, shape, motion and colour. ** One theory is that visual disturbance
from poor stereography mimics the visual disturbances that accompany the
toxic effects of alcohol, poisons or of motions of the inner ear that lead
to seasickness. So our natural reaction to poor stereography is to feel
nausea and also eyestrain if the camera alignments force our eye muscles to
exert unnatural tension for extended periods of time.
Giving clients a grounding in visual perception enables professionals wishing to capture 3D content avoid many of the common 3D pitfalls and produce imagery that is easy to edit and view for greatly extended periods. Inappropriate camera alignments at the editing stage too can induce eyestrain through miniaturization, motion artifacts,
excessive parallax and incorrect object scaling so must be avoided.
Reg Sanders as a Stereographer with a strong visual background as a 2d drama director, along with Shoot 3D can offer assistance at every stage of the stereoscopic video production process. The steps include equipment specification, production
grammar advice, shot-by-shot analysis, on shoot shot, complete post
production services using industry-leading products such as Quantel Pablo
and Mistika and also projector calibration.
A 3d Industry Insight Workshop is being held at ProCam North, in Manchester on Friday, June 18th - featuring 3 x 2 hour sessions. For information contact reg@shoot3d.tv

Ghost busting and Lanc synchronisation.
This was a sequence filmed under 'test' conditions with 2 HVR-A1 cameras.
They are not genlocked but ARE 'synched' using a Sony Lanc controller, they are
synchronized to within 5 milliseconds. We shot loads more - but on this shoot it wasn't very exciting,
so I have only posted the one clip. What I did learn from this shoot was about the concept of 'Ghost busting'
If you look in the background you can see the double imaging of the floor indicator above the lift doorway.
We converged on Rob (the guy in the black shirt) from about 3 metres - and the background has gone way beyond sensible convergence with the massive disparity that you can see. Well, this fact combined with the high contrast image creates 'ghosts' and there are some post production solutions that offer a 'ghost busting' service...

A 2d commercials director in the world of stereo 3d.
As my training continues I seem to understand less and less...
There is so much in Stereoscopy that seems to be counter intuitive when you have spent the last 20 years working in 2d. So far my position on the interocular is that you should approach each job differently.
I have read conflicting articles and been given conflicting advice, and I realise that the distance between the cameras is critical to the amount of '3dness' on the shot and how much of the shot will be usable or rather 'fuse-able'.
This is my take on I-O or if you prefer I-A so far... I'm not saying it is right - it just what I have learned so far.
Don't Shoot The Messenger.
The average distance between the human eyes is 64mm (2.5 inches for those that still use imperial). If you hold a coffee cup up in front of you at arms length and concentrate on the cup. You can see the front and a little of each side of the cup. If you could have a drink of some magic potion that would make you grow into a giant - say 12 feet tall - double your size in all dimensions you would hold that cup in front of you and be able to see that little bit more around each side of the cup. So if you shoot with your cameras say 130mm (5 inches) apart then you are replicating the view of that 'giant' person. Which means that the cup will look small, half the size. Or put another way, from the perspective of the cameras the cup has shrunk... So when you show these images in 3d the amount of 'depth' in the picture of the cup would indicate to your brain that you have turned into a giant, or more reasonably this is a smaller cup than 'normal' because you can see as much of the cup as you would have, had it been half the size! Stay with me, I did some tests and am happy to email them over... reg@shoot3d.tv. I bought 2 identical cups - one large and one small and took some very accurate still photos (based on the above) and compared the results - then I made 3d photos and showed them to a group of friends - there were no size cues in the pictures - just the stereo photo's of the cups. Without fail I could 'make' the big cup look smaller in 3d by using a larger interocular IO than is natural. So the 'Hyper Stereo' stuff that you may have read or come across is REAL. Then I found out that some of my sample viewers have enhanced 'stereo-acuity' (ability to judge / perceive 'depth' - relative size and geometry - based on interpretation of vertical disparities).
Now - where does this lead me. If you have seen any of the Sky TV 3d coverage of the UK football (Soccer) matches in 3d then those of you with high stereo-acuity may have found the 3dness a bit strange - and giving you the sensation that you were watching 'miniature' sized men running round a field! This is because some of the cameras had quite a large interocular. The view is generally that you can 'get away' with this in sport.
Here's a thought...
If you were shooting a commercial in stereo 3d, you have 2 guys, one with an aftershave product that is supposed to make him more attractive to the girls, then you might make him slightly 'larger' (hypostereo) by moving the cameras closer than the human IO (say by 10mm) and shoot the other guy in your commercial who is the 'loser' wearing the 'nobrand' aftershave - well, you could shoot him with a slightly larger I-O`(hyperstereo), again say 10mm - this might psychologically give an advantage to the 'hero'. I'll try it out and let you know if I get a script in for a 3d commercial.

A Christmas Carol - Not a good 3d experience DEC 2009
On one of those rare 'days off' moments - I decided to take the kids to see a 3d movie, kind of busmans holiday! Nevertheless we turned up at the local multiplex which had recently had its main screen converted to 3d.Infact, it was using the new Dolby 3d system which I had read was vastly superior to the Real D system, so I was keen to hand over my hard earned and get into the cinema... We took quite a load of kids with us, as our kids brought their friends who brought their friends! We ended up with 12 kids and 3 adults.The first thing I noticed was that the glasses were duly handed out, beautiful shiny mirror look lenses and deep wrap around sides. I later discovered this is to maximise light the coming into each lens. During my stereography training I was told that the Dolby 3d system uses a combination of filtering to very finely control the colour information to each eye, so that although the channel separation is slightly less than the Real D polariser system the final result is better overall colour reproduction. I was looking forward to this screening, probably more than the dozen kids I was sat with!
I noticed there was a lot of activity pre-movie as the audience kept popping up and down to the attendant getting 'wipes' for their 3d glasses, getting them cleaned. I had to for some of our kids.
As the lights went down and the opening title sequence began I noticed I could see something in my lenses.
Again I cleaned them but it wasn't on the lens. What I could see was the reflection of my eyes and eyelids and lashes in the lens, as they were so shiny. Also the ambient light in the auditorium was very high, not helping the situation. In the UK they have strict regulations governing light levels in cinemas, and generally the cinemas have 3 levels. The walking in / walking out level well lit 'house lights' - then the next level of dimming is the spot reel or the adverts before the main presentation, I assume they have that lighting so that we can juggle our popcorn and kids, and get settled for the main movie. Finally, darkness for the main feature.
However, in my cinema trip, the lights never dimmed down to full darkness for the movie. You could extend your hand out and clearly see a shadow cast on the floor from the lights above. This caused problems with the 3d viewing because the images I could see through my lenses were overlaid with reflections, also the movie itself had a fairly 'dark' feel to it (being set in Winter in Dickensian London).
And therein spoilt what should have been a great 3d experience. The trouble is these multiscreen movies have very few people involved in their running. It's all done by computers... as they say. A Christmas Carol started and I went off like Scrooge trying to track down the projectionist. I went to the front of house area, to find a couple of students selling popcorn and coffee, they told me the projectionist had 'gone home' and would be back later to turn everything off... I asked for the manager, there was none. So the next day I'm on the internet and phone trying to find someone from the Vue Cinema chain to talk to... No luck. I sent an email to their customer services team who eventually reply with some brush off corporate letter about local planning regulations on light levels in public buildings... And didn't take on any of my points about 3d needing more careful light control than 2d so that the viewer can properly extract disparities and depth information for proper 3d viewing. I think they were worried about me trying to get my 50 quid back from them for the trip, but I made it clear I just wanted some technical dialogue on their procedures and spec for 3d cinemas... Bah humbug!

The walking in / walking out level well lit 'house lights' - then the next level of dimming is the spot reel or the adverts before the main presentation, I assume they have that lighting so that we can juggle our popcorn and kids, and get settled for the main movie. Finally, darkness for the main feature.
However, in my cinema trip, the lights never dimmed down to full darkness for the movie. You could extend your hand out and clearly see a shadow cast on the floor from the lights above. This caused problems with the 3d viewing because the images I could see through my lenses were overlaid with reflections, also the movie itself had a fairly 'dark' feel to it (being set in Winter in Dickensian London).
And therein spoilt what should have been a great 3d experience. The trouble is these multiscreen movies have very few people involved in their running. It's all done by computers... as they say. A Christmas Carol started and I went off like Scrooge trying to track down the projectionist. I went to the front of house area, to find a couple of students selling popcorn and coffee, they told me the projectionist had 'gone home' and would be back later to turn everything off... I asked for the manager, there was none. So the next day I'm on the internet and phone trying to find someone from the Vue Cinema chain to talk to... No luck. I sent an email to their customer services team who eventually reply with some brush off corporate letter about local planning regulations on light levels in public buildings... And didn't take on any of my points about 3d needing more careful light control than 2d so that the viewer can properly extract disparities and depth information for proper 3d viewing. I think they were worried about me trying to get my 50 quid back from them for the trip, but I made it clear I just wanted some technical dialogue on their procedures and spec for 3d cinemas... Bah humbug!
