After seeing the video of Tupac at Coachella, I was really curious about how it all worked. It was obvious that it was a re-created, digital version of Tupac, but how did it look like he was really there? I did some research and found the video above. It’s actually a very old technique (from the 1860s), called Pepper’s Ghost. Using a plate-glass and special lighting techniques, it can make objects seem to appear or disappear, transparent, or make one object seem to morph into another. In short, reflects an image at a 45-degree angle.
Here’s what the President of AV Concepts said about the Tupac production, in an interview with MTV:
The Tupac hologram was several months in the planning and took nearly four months to create in a studio…he said a comparable one could cost anywhere from $100,000 to more than $400,000 to pull off. “I can’t say how much that event cost, but I can say it’s affordable in the sense that if we had to bring entertainers around world and create concerts across the country, we could put [artists] in every venue in the country,” he said.
Very interesting technology.
