After years of waiting a dream becomes true.


One Barco 4K Cinema DLP the DP4K-B32 was install on 3th june 2011 at my home cinema.


With this 4K I did a lot of tests also one with a new Infitec System calls

3D of excellence

and as it went very well I order a second Barco DP4K-B32.


The old pr. room that have the Barco DP 2000 inside was removed



the old pr. room was gone....




This second was installed last Friday the 1th july 2011.


After this install i put the new Infitec System on(temporarily at the lens) set up a computer that

feed via 4 display ports the two 4K DLPs each with a 4096x2160 image.


the 4K 3D computer with 4 displayports to feed both 4K Barco




4K Pr. number one is down at the cinema and got the install



a fist light with a true 4K test pattern



I hear from Barco Infitic and other company's that must be the first 3D 4K passive set up in the world

with a 4K DLP system.


There are less than 20 installations worldwide at this moment running a DLP 4K Stack but not one of them show native 4K 3D content.

So the 1.July 2011 was a World Premiere



4K Pr. number 2 arrives the cinema



As 4K3D native with one 4K DLP is may a good year away and shutter have also some weak parts I decided

to go with this passive 4K 3D set up as it have a lot of advantages like:


-having 4K 3D TODAY and no need to wait for next year new input boards that makes native 4K 3D possible with only one 4K DLP

-double the brightness compare to a active 3D single pr. set up

-see both pictures at the same time (for blue ray in 3d its very important as 3D motion looks far better)

-no need active shutter that have Front Wave Distortion Bug and other picture quality decreased issues.


AND thanks to the new 3D of excellence Infitec System

-no ghosting AT ALL even at this high FTL numbers!

-no speckling from silver screen

-no hot spot from silver screen

-no emitter problems in some far away areas

-more brightness



a very rare picture my Barco DP 2000 with two new 4K Barco



As I report since long time ago at AVS with a 4K DLP the source will becomes very important as this is in 99% the bottleneck and will limit the

possible quality.

If you scan even a good 35mm print most of the time you will find not more than hd resolution as the 400 or 800 asa films not contain

much more than this.


That's why I spend since many years much time money and action to record my 3D Stills with the best possible digital cameras that are

buy-able and possible to make a mirror rick in 3d.


Now for the first time I know why I did that as the bottleneck is not anymore the display system!



Its hard to describe how good this pictures looks.

One very big advantages from using 4K DLPs are that you can go very very close to the screen without any visible pixels and decrease

of details.


That's why I create a new first row that have in flat format (1,89:1 = 4096x2160 that I most use to display my 3D stills)

0,8 times the distance from the screen wide.

The displayed image is there 5.4meter wide 2.86meter high and I sit there in only 4.4meter distance.


At this distance the picture is still very sharp no way you can do it with only 2k resolution as there the picture suffers form the

4 times less resolution.


The 3d picture is very bright thanks to the Barco DP4K-B32
http://www.barco.com/en/digitalcinem...uct/2310/specs

with a 6000 w. xenon lamp that have around 32.000 lumen and

the new Infitec system that have set a world record light out.

This system is even brighter than Dolby 3D System and allows me depends on what size I use in

flat 5.4 m wide or scope almost 7m wide till over 40 FTL in 4K 3D measured after the glasses what you eye see!

In cinemas you must be lucky to see more than 4 ftl in 3D and new tricks not solve this issue.

Some will say to bright but some early visitors may think first the same but after they see it they say that is bright very nice

No one say it was to bright.


For all that have no access to high quality 4K 2D or 3D material a 4K pr. make not a big sense beside you are future proof.

A good BD in 2D looks upscale to 4K not far better.

You can only see a small improvement in picture quality it looks a bit more naturally that's all.

But if you sit close to the Blue Ray picture in about 1.0 times the screen wide in distance it makes sense as you than with a 4K DLP can not see any pixels.


It will be still a long way and will take much action to rebuild the cinema that it will be look again nice and with all the new much stronger exhaust air system new sound proof projector room, new system to not need any porthole glass but it will be make fun to plan and build it.


the Barco DP 2000 was gone the 2 new Barco 4K with the

temporary Infitec set-up





I have to say thank you Barco (Ignance, Dirk and Philippe) to help me a to create this setup as for sample I can use

new software to feed my 4K 3D Images that will be soon(in some weeks) released to the public and much more.


Also Infitec that give me the new 3D of excellence filters to test it and the offer to equip both Barco DP4K-B32 with this new filter that I can

move in and out to have the flexibility to watch 2D and use at the same time 3D.

This new filters and glasses will become available till end of this year.


Also Mr. Trautner from Austria that build first time this kind of computer i have to say thank you for your support and the time you

spend with me for this project.


FTT in Germany did also a good job to install and adjust both pr.


Mr. Peschke (the In Camera Magazin called him the 3D brain from Germany) I have to say thank you as well as

he creates with me this insane Leica M9 3D 3D Rick that can do 3D pictures that have a quality that I never saw before.


All this was not possible without the 3D processing program Cosima from Mr. Herbig Germany.

This program allows to do anything you like for 3D pictures and 3D video and as he update his program all the time.

It's a perfect tool and a good workflow for me in 3D.


Last I must say I was very surprised with all what can go wrong in this huge project that not anything major

went wrong and all is ok from the beginning on.

That's a big surprise for me.



new first row at 0,8 times the screen wide in distance



But the biggest surprise for me was how good this 4K 3D pictures look.

I expect that they should be good but I never believe that the distance to my old setup (single Barco DP 2000 Cinema DLP) that

was already very good was so great.


4K with the right display the right source puts you into a new world if you sit close enough.

Its like you looking outside a window and you are there inside the picture.


Next big improvement will be a holodeck

Wow Wolfgang, so you actually went ahead and did it. No decay issue with the new silver screen? You mentioned passive is not ideal, not faster than active, unlike the hitachi claim, I posted a few months ago, as silver screens have an extinction time of 150 ms, you said.

Wolfgang, this is nothing else than a sensation! Spectacular


You did it again, congratulations!


Funny to see this huge 2K projector in comparison to those new big 4K animals!

Your screenshots look very promising

today i drove 1200 km (750 miles) to see wolfgang´s setup..

we don´t have many speed limits here in germany but it took almost 16 hours to get there due to bad weather even with 525 hp and max speed 200 miles per hour ;-)..


but : it was absolutely worth it.


casino royal was the first bluray : never seen better before!


later wolfgang showed us 3d pictures from dubai and the maledives : the only chance to stand the 12000 watt of light : suncream and sunglasses :) we felt to be there!!!


thanks wolfgang!

Didn't they show at least one passive demo on that Barco stack at that 3D gathering Peter attended, RealD, from what I remember from the reports here?


Of course that was not a permanent installation, but a brief semi-public demo. So you still have the first permanently installed 4K DLP 3D set-up in the world, wow.


And considerably bigger and brighter than that (small, ahum) 152.5" (386.2 centimeter diagonal) plasma. I came across that picture Lang AG emailed me with me in front of the Lang owned unit, clearing some old email the other night. No I didn't get it in the one week free 'rental' prizedraw at ISE;-(.

thanks for all the nice words!


as i have post a handfull 4k stacks working worldwide right now but they either display 4k in 2d at 24p or 3d2k upscalle to 4k3d and not "native" 4k in 3d.


the event you mentioned they show there 4k in "2d" with 24p and 3d from 2k source material upscale to 4k so not native 4k 3d.


silver screens not have any "extinction *time* of 150 ms" i say that silver screens have

extinction *ratio* in the best case at 150:1 that means the ghosting is bad.

as it was not that good thats the reason why the ghostbuffer the source material

for almost every 3d movie.


the lens is the 1,27-1,86

I have 2 setups like these going in next year.


I was surprised by your quick anlaghen.


When it comes to 3D the more you know, the more you realize what you do not know...


I have been prepared to go full blown RealD with their large polarizers but I took a class at Infocomm on passive technologies and the developer of DETHq a competing z-screen and pc 3d program admitted that GHOSTBUSTING is always a requirement.


That presents a problem for passive polarized.There are no video processors with ghostbusting.


The Depth Q guy did mention that the Infitec is an asymmetric process where both eyes do not get the same signal (as in Polarized passive), he asserts this can be seen on content and that some people may be sensitive to the inter ocular color differences.


So I left Infocomm a bit confused but like Wolfgang decided to go with two solid passive filters after seeing the excellent demonstration of the new

superbright Infitec filters shown here on 2 10kw christies uhp.

a) dual aspect ratio. Can you preserve convergence in dual aspect ratio lens memory or just one aspect ratio. What happens to cinemascope.Gut?


b) inter-ocular color differences, any side effects from having different color wavelengths arriving to each eye?


c) Color correction- was anything special done to the barco's in order to color correct? in single projector dolby this is a pending item. Or with two projectors it is very simple basic correction, like Manfred Reich said.


thanks!

That's right you mentioned a ratio, not a time, guess that's why I asked for clarification;-). Yeah, now I remember that 3D was upscaled. Anyway an amazing project, Wolfgang, congratulations on your world's first.



BTW, with the Infinitec do you still need to 'ghost bust'?

Just in case it wasn't clear, I'm pretty sure he didn't go with a silver screen (since he went with Infitec instead).

Of course Infinitec is the different colourfrequency passive system. He didn't mention any work on the screen (KinoTon), so I did wonder about that, but I overlooked the workings of the Infinitec system, eventhough I have seen it demoed at ISE. Thanks Darin.

some more infos.


here a picture how the 3d4k picture was created with the COSIMA programm.

a 4096x4320 resolution(2160x2) picture split in up left and down right part from the

3d picture.




thats my old canon 5d mk2 a big good heavy 3d camera that i use

till last year.





here my last 3d camera a hand build leica M9 3d camera.

Mr. Peschke desing the rick

Leica makes the coupling and sync box and the new cover.


Leica have to redesign the top part of this camera because of the original M9 up cover plate have not enough room for the conctor for the sync but a M8 up cover plate have it.


so this two M9 are the only 2 units that Leica build that have a M8 cover plate!


i bring all together and procure a very high end beamsplitter.


that Leica 3d rick is a very very compact full format digital 3d set up and the best i ever had.

some people say its the best full format sensor still picture digital camera in the world and i must say that i saw till today nothing that beats this M9 camera in picture quality.




i build 3 ricks.

one i use the other one is with leica and the 3th

is for someone that is as insane as i am about 3d
.


sad that Leica not produce """this""" camera:

please note that this was a fake picture i create!



but if such a high end 3d camera will be ever produced i will be very happy.


this rick i use have one big advantage over a true 3d camera

with a fix optic distance.

you can there adjust the base

between both optics but this beamsplitter cost you around 55-60% light

produce color problems compare to a real 3d camera.


i hear that some companys will have soon a real good 3d still picture camera.

i guess sony and panasonic will be a candidate may canon as well but i doubt

that they will comes with a full format digital 3d that match my quality

ideas.


but the next dream will be to have a true 4k video 3d recording like for sample

a red epic like they use for shooting 3d films at this moment.

sad this rick will be huge and havy but i hear also that some camera manufacturer will have a video 4k function for film very soon.


a problem will be that at this time the 4k dlp can not display 4k native resolution with more than 30 frames.

the new inputboards that can do it in 48p and possible 60p in 4k native

will take some time.

Hey Wolfgang,


Can you please share some of your 3d shots that you took with you 3d camera? I am sure of of us here would love to see and download some of your best works. also, what are you using your camera for. is it for everyday photos of your family and social life or are you doing some kind of professional photography work with it (like weddings, party, etc. )? thanks.
