    Default Tupac "hologram" used last night at Coachella

    NSFW based on language
    http://www.youtube.com/watch?v=1aNLCw8Obtw

    Apparently it looked very realistic in person and on TV. So realistic that laser pointers seemed to terminate and reflect on to his body

    What technology was used for this. People are already talking a Micheal Jackson tour with this technology. New or old?

    it's basically just video projection on a scrim. you see it a lot in fashion shows these days.

    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    Its just ole "Pepper's Ghost" done with a new, specialized, coated, stretched plastic film or films and good quality video projectors.


    They use "Holographic" as a marketing gimick. It is not a hologram, its a reflection. Note the required EXTREMELY dark background.

    The film probably comes from 3M, as does the controlled scattering film used to allow video projection on glass windows.

    So old a technology, they are counting on marketing and gimmickry and a lack of education in entertainment to call it "New" again.

    The retired Imagineers at Di$ney who reinvented it the sixties when it came from the 1860s must be LTAO.

    Although the high tech plastic is world class material. Nice to see it looks like their using mutiple layers, courtesy of the pointer, that was a little detail that was puzzling me.

    Thanks guys, I figured it wasnt a hologram which is why I put it in quotes. If you look at it from different angels (ie right stage or left stage you seem to see more of his sides) Is this how Di$ney makes their ghost "the secret way" in their haunted house?

    I did notice the darker background than the others. For once, some idiot in the crowd with a laser pointer actually gave us something useful

    whoever did the video editing did a good job, i notice the usage of covering his mouth with the microphone as making the mouth movement would have been very intensive. It still looked very good from my amateur eyes

    are you talking about the ghosts dancing in the hall? if so "ghosts" are under you illuminated with really bright lights, so you can see their reflection on the glass superimposed over the room behind the glass

    Thats Pepper's Ghost if the Glass is at about 45 degrees.

    Disney has changed techniques over the years.

    Looks nice on television, but I wonder if it is just as convincing when seen from the audience.

    If this is a sheet projection, probably all off-axis viewers see something like this;

    ,instead of this.

    Elvis has been and probably still is on tour.

    I did lights for an Elvis tour a few years back.

    They just used a big video screen to project Elvis onto and had a band on stage... Still sold out arenas though.

    I thought it was a bit weird to be honest..
    If in doubt... Give it a clout?

    Looks like they use a bunch of closely placed sheets to help with that.
    There are coming soon, linticular sheets, so I can see depth of parallax going up.

    I heard from someone I trust with their opinion and they said it looked pretty real in person

    Err, yes... So much so that they have their own 'holographic' pop star who apparently regularly does sell out shows... And we thought X Factor were the kings of manufactured pop rubbish

    Eh, so it's just a projection on a glass wall huh?
    Are there any "real holograms" which don't make use of mirrors and glass planes? Even if still very bad quality and not used for anything useful, would be very interesting to know.

    For the best of "real holography" in 2013, consider a meter sized glass display cube on a pedestal. There is a single tiny light source on the ceiling aimed toward each of the four faces, like in a museum. The objects inside are in full color as expected of "real" things. How do you know the objects inside that cube have mass? You can't. The walls of the cube are holograms.

    But there are some very interesting things an artist could do with subjects in a cube like that. Combine that with other projection tricks like the Pepper's Ghost. That's potential, but the reality is a box the size of a breadbox with a freakin' real image inside, using LED and/or despeckled laser light for illumination and the best full color recording materials available today. Throw the budget of a very large sculpture, or a reasonable film at it and one would probably make a splash as big as the Tupac nologram.

    It looks like they have a very short distance to do the focussing, so could this make spatial filters more compact?

    [edit] It would make graphics lasers absolutely spot on - being able to focus and de-focus the beam to different sizes. Divergence modulation if you like. [/edit]

    Neat display, but nothing compared to a real hologram.

    "It works by focusing laser l??? to produce plasma excitation from the oxygen and nitrogen in the air."
    Makes perfect sense, it's magic.

    Awesome. 'They' (whoever they are) say the old ones are always the best. I first learned of Pepper's Ghost in a small book when I was a small kid. It looked like a neat idea, and not at all mysterious. I guess what gets people every time in cases like this is the scale of it. One thing about that always puzzled me: Assuming some of the earliest Pepper's Ghosts in theatres were also intended to amaze people, how did they get such huge sheets of glass, before anyone else seemed to get it? Multiple panels with cunningly hidden joins? Seems to me a strange use of expensive large sheets in times when I imagine far more demanding uses would be grabbing all of it that they could get. To put it another way, if such large sheets were commonplace in shop windows, no-one would have been very mystified by Pepper's Ghost in a theatre. Or would they? Cos it seems to still be working, even now. Maybe Barnum was right. Except 'they' say it wasn't Barnum who said it! Pepper's Ghost seems to apply beyond optics.....
