Agreed. It's refreshing to see intelligent journalism of this nature where we get to see the interviewer simply facilitating the real stars of the show rather than asking vague and general questions.
These days you almost already take for granted photorealistic digital faces, cars etc. I found the simulation of real-world recorded lighting situations even more interesting than the digitizing of faces. Fascinating presentation and thank you for not making it just three or four minutes long!
This is a really interesting video, one of your best I think. Pal Debevec is great at explaining things and you can see that he is really into his work and Norm's questions are on the spot. Thank you, Tested:)
AWESOME!... Norm is the best for this job! He let the guy talk and knows about the subject enough to have a decent conversation. I had my doubts in the past but...not anymore.
Paul Debevec, since I have seen your conferences on all RTC, I take such pleasure to have gathered a lot of your notes during the talk. Very interesting your path with various roles but constant determination over the two decades you have been in the business. You are a great inspiration !
What an amazing technology. Many people really don't realize the huge impact that lighting has in every aspect of our perception. Can't wait to see more.
this video kicks ass. the detail and awesomeness, and the guy you are interviewing is great. i have hypothesized about light rooms like this for many years, and it is great to see it really exists. lit by the lighting of a real location!
That is so cool! The reflections in the mirror balls actually looked like buildings and the sky! I could even visualize that cathedral, and I don't even know the one they're talking about.
it's essentially an inverted digital camera:D rather than pixels capturing light for a digital space the LEDs act as pixels that emit digital lighting on real world objects.
***** oh i was talking about the light rig not the cameras. the LEDs are the pixels in that respect. also didnt intersteller or soem other modern space movie do something similar to get simulated lighting on live actors? only they used giant powerful flatscreens rather than specially rigged LED arrays.
Paul Debevec legend! great video, felt nostalgic seeing pauls first shot hdri's (we all 3d guys used to use them back in the day), actually illuminating in real life amazing!
Really glad to see this here. I've seen Paul's work over the years and it's always impressed me. I experimented with two light source synthetic lighting inspired by his work years ago. I took two pictures of one scene, with two white lights, then using Processing, let you adjust the R,G,B intensities of the two images overlayed on top of eachother, and you can see the shadows interacting and color mixing live. Really fascinating stuff! :D
This takes me back to when I started doing 3D graphics and rendering. Pauls HDR light probe gallery was one of the most important resources for me back then.
As much as the build videos are super enjoyable, this was one of the most fascinating episodes you've done. And Norm is asking all the right questions. Good job!
This was my favorite video by far. Awesome job, Norm asking relevant questions to get good info to us, and I really appreciated your tour guide's ability to use lay men's terms so we can all understand. That was so cool.
I had to work with lighting myself, for a short animated video, and I was in the process of designing a rig for 3DStudio that would help me manage different conditions such as bright noon sun, midnight, interior candle light, that sort of thing.... and as I added lights and controls to it, I realized I was spending more time rigging the light than actually making the video lol I concluded "yes, if it's ever completed, it'll be a very powerful rig, but I can get the same results by throughly designing the light _as_ I animate the characters" that thought process took me about a quarter of a second.... I just went "oh, gosh, you're terrible..." _delete!_ if you really want to account for the different angles, and colors and everything, it's like he said, it's a multi-dimensional array of millions of numbers that can make you go crazy if you don't _really_ need it.
Thank you for this video. This is exactly what I have been trying to reproduce for years. It is great to see something like this that is up and running and working.
6:30 I wonder if they managed to synchronise the change of the lighting with the framerate of the camera somehow or if they are not changing the ligthing for at least the duration of few frames .
I'm very impressed, this is awsome! But what about metameric colors? He said, that they can simulate almost every light color due to the additional amber and cyan. But using LEDs the spectrum still will be consisting of very sharp peaks. Maybe your eye will see the "same" color, but what about the reflection of colored fabric that acts as a filter for a now different spectral source? I reckon, there still are differences in comparison to the original light.
Id love to see a followup video showing the processing after taking the images. This was the most interesting video you've mad in a good while, well done!
great video, i love the narration! Well prepared questions. As a followup video, i would love to see more information about what happens after the capturing and what the steps to the perfect lit and working 3d model looks like.
Does anyone know what type of polarizer they are using? I see some hints for either linear or circular polarization but at the same time I see hints that would rule out both options.
Who's here after Thalapathy 68 update 😅😅.. Like eh podunge... Madan Gowri, Enowaytion Plus mattum vere enthe youtube channels vanthalum like podevum.. Ennai video le mention pannevum 😂😂😂❤
7 Dimensions. I guess that would be 2 dimensions for the resolution of the surface of the spherical light-field, 2 dimensions for directionality of the light passing through each of those points, 2 more for directionality of the lighting and the last one is time for the animation? That's A LOT of data. I'd like to know the resolution of each of those dimensions. Even with fairly low resolutions of each dimension it gets staggeringly huge FAST.
i could see this lightstage technology be used in forensics. like i dunno some ransomer has a photo of their kidnapped victim and so they recreate the lighting in the photo to determine where it could have been shot. like if the top of the victim is more lit they are in a basement or a rverbed like the terminator.
if there are any shiny surfaces in a photo, then sure, you could get some information, but purely from a face, you wouldn't be able to do that. It's like a picture with a strong blur filter, you can't easily recreate the original. Just look at Paul's and Norm's faces and compare them to the shiny spheres. You can tell "more or less" that there's a strong light above them, but you can see the details only in the sphere's reflection. Not to mention that kidnappers rarely us 1Dxs and send full res pictures along with the ransom note. ;)
Mopic3d oh was talking in general not just faces.the light rig is basically a meat space panorama dome able to simulate lighting conditions. Like if the ransom photo is in a riverbed the only light will come in the form of a strip so if the the body in the photo has a strip the stand in will have a similar in the light rig.if I male sense.
You can theoretically simulate whole scenes if you have a light rig the size of a soundstage. They just have a tiny one for faces because it is cheaper I assume.
what do you mean lit the right way as if he's really there? how do you make the brain think through lightings that the image is the human there? how do you get such a clear image? is the design of an eye ball including retina or something for the lighting? looks kinda like it, so why the 6 lights per thing?
I think a rotating ring would give better dynamics if you forget about what it looks like in the human eye and sync light source controllers and cameras together in the computer.
Those boards clearly had controllers for every LED. If I were designing it, I'd probably use an RS485 serial bus to communicate out to all the boards. I'm sure every one of those boards is a stand-alone controller with power and data signals going to it.
Loves how he tries to credit his team members as much as he can.
These people don't get the attention they deserve
Hear, hear
Totally agree. Nothing more annoying than the guy who claims he is the creator of all things because he asked someone else to do it.
You are absolutely right, dear sir. This is such a rare virtue to acknowledge contribution of others on your projects.
True, it's a bit futile though because nobody is going to remember the names.
Paul is one of the most intelligent and human persons I've ever met. I met him several times at siggraph. SMRT.
Norm is so well prepared and asks adequate questions.
Agreed. It's refreshing to see intelligent journalism of this nature where we get to see the interviewer simply facilitating the real stars of the show rather than asking vague and general questions.
+Aditya Gangal Definitely. It really shows Norm did his research beforehand and expects more of his audience.
this is why i love watching tested. always something interesting, doing the proper due diligence, and covered in a way no one else on youtube does.
This is one of your best videos.
agreed
Ditto!
yes!
The real hero of this video is Joey. Good job with all these crazy lighting conditions!
These days you almost already take for granted photorealistic digital faces, cars etc. I found the simulation of real-world recorded lighting situations even more interesting than the digitizing of faces. Fascinating presentation and thank you for not making it just three or four minutes long!

What an amazing technology. Many people really don't realize the huge impact that lighting has in every aspect of our perception. Can't wait to see more.
We need part 2 where digitized Norm is put into some lighting scenarios.
I agree. Looking forward to see what the digitised result looks like.
this video kicks ass. the detail and awesomeness, and the guy you are interviewing is great. i have hypothesized about light rooms like this for many years, and it is great to see it really exists. lit by the lighting of a real location!
That is so cool! The reflections in the mirror balls actually looked like buildings and the sky! I could even visualize that cathedral, and I don't even know the one they're talking about.

Mind boggling technology.
There's a demo made by Nvidia where they recorded someone with one of these and made it into a real-time animation
+Rick Sanchez you would just put the people inside the computer
+Rick Sanchez you would just put the people inside the computer
The capabilities of this machine are... spectacular ;)
Wow the demo with the Christmas bulbs and the lighting reflection was quite amazing. Thinking outside the box. Awesome!
Paul Debevec legend! great video, felt nostalgic seeing pauls first shot hdri's (we all 3d guys used to use them back in the day), actually illuminating in real life amazing!
Paul Debevec - a living legend for the CGI world #legend

Finally a really great Tested video. Please do more like this!
This takes me back to when I started doing 3D graphics and rendering. Pauls HDR light probe gallery was one of the most important resources for me back then.

Oh man, Norm is LOVING this! Kid, meet candy store.
I could have watched another hour of that. Great video, well done Tested.
A masterpiece of engineering.
Holy shit, the cathedral skybox is outstanding. This is really something.
Perfect interview. Congrats to the Tested team.
Top notch content guys! =D
Interesting topic and people and Norm knows enough to ask really relevant questions.

Thank you for this video. This is exactly what I have been trying to reproduce for years. It is great to see something like this that is up and running and working.
This is one of the coolest things I've seen!
That's fascinating! I can vaguely make out the scenes being portrayed in the mirror balls. The cathedral was especially convincing.
I remember Debevec's to old animations. Groundbreaking stuff.
This is both incredible and awesome. Proper lighting is everything!.. excellent video!
Tested is so informative and educational.
keep it up guys, don't go for clickbait
I'd like to see an in-situ render of an actor's face in the digital environment that the lighting is mimicking.
I love how pro you are at this Norm :D
Congratulations, Norm!
Amazing technology. Thanks for making a Video about it!
Thalapathy 68 ❤🔥
This was incredibly cool. Thank you so much for making this video. I look forward to showing this to all of my media production friends.
very interesting i would love a whole video on just lighting scenarios.
This was awesome, well done +Tested for another great video. Anyone else notice Paul's overshirt with the Avtr Weta Shots Dept on it? Nice!
Absolutely Fascinating
I did not expect you were gonna be able to see the places in the reflections on the balls; blew my mind!
I've worked on those tutorial examples before in HDR, pretty damn cool
6:30 I wonder if they managed to synchronise the change of the lighting with the framerate of the camera somehow or if they are not changing the ligthing for at least the duration of few frames .
Norm is great, really impressive interview.
Always love a good Testees video
This is so amazing! It's also another reason to never ever believe video evidence (i.e., propaganda) that something happened.
Camera operator had to work hard that day haha.
This really is a great vid! And what a great work to get to know. Hope we get to see more like this!
I'm very impressed, this is awsome!
But what about metameric colors? He said, that they can simulate almost every light color due to the additional amber and cyan.

Can't wait to see when this is miniaturized down to even smaller and less expensive levels. Long distance phone calls would never be the same!
JW3HH
Id love to see a followup video showing the processing after taking the images. This was the most interesting video you've mad in a good while, well done!
It's amazing how you can see the scene quite clearly in the balls when the camera zooms out.
My god.... it's full of stars!
Nice reference there :D
Norm, you are an awesome interviewer.
great video, i love the narration! Well prepared questions.
As a followup video, i would love to see more information about what happens after the capturing and what the steps to the perfect lit and working 3d model looks like.
great interview.
this is absolutely amazing
An extremely interesting insight into lighting
That was incredibly cool and well put together from an informative standpoint. Thnks :D
this is unbelieveable, so cool!
Great Video! Never saw this before.
oh the human mind, amazing
Does anyone know what type of polarizer they are using? I see some hints for either linear or circular polarization but at the same time I see hints that would rule out both options.
Very cool video. Paul is an amazing presenter of information.
This was awesome!
The truck in Terminator 2 was driven by Robert Patrick - T1000... Arnold was on a motorcycle. Come on man!
Such a heresy!
Yeah I was yelling at my monitor when he said that.
Hasta la vista, baby

Was this the thing in "The Congress"?
Yes.
simeon24 Cool. Loved the movie. They might have mentioned this in the Tested feature, but it was so long, haha.

This is superb tech, I'm tempted to go get some polarisation film for my brilliant $100 lighting setup at home XD
So Duke finally sold the secret family recipe, forcing Jay into another line of work?
this is really amazing
Fascinating stuff!!
Well this is nifty, could this also help with space observations? Like to detect further light sources or recognize it better? Just a thought.
Wouldn't you want darkness for that?
i could see this lightstage technology be used in forensics. like i dunno some ransomer has a photo of their kidnapped victim and so they recreate the lighting in the photo to determine where it could have been shot. like if the top of the victim is more lit they are in a basement or a rverbed like the terminator.

We are here after #Thalapathy68 Announcement
This was really interesting! 😀
Paul is wearing the WetaDigital Avatar Shots Dept shirt. Honour.
thanks! super useful info!
Awesome stuff.

it's the tested CHRISTMAS SPECIAL everybody...
I think a rotating ring would give better dynamics if you forget about what it looks like in the human eye and sync light source controllers and cameras together in the computer.
it's amazing) thank you very much)))
How much power does it use and how much does the setup cost?
So cool!
I wonder if, besides still photos, they can project video in that environment.
is it with a goal to improve everyone's images including in real life like from improving overall life/health quality for everyone?
really cool norm
This guy is so neat!
I wonder how the LEDs are controlled, it's not possible simple multiplexing them, the high speed camera would record that
every cluster of LEDs have their own micro controller, by the looks of it.
Those boards clearly had controllers for every LED. If I were designing it, I'd probably use an RS485 serial bus to communicate out to all the boards. I'm sure every one of those boards is a stand-alone controller with power and data signals going to it.
it looks like something darth vader would sit inside of on the death star
I wish they would remake Myst in VR using this technology.
this is so cool.
How many cameras there?
