huhuhu... so today i will share with you guys something intresting about how they make gandalf loos bigger n how hobbit looks smaller and believe it or not is not using any CGI. Peter Jackson is Awesome!!!... this post actually i paste from www.cracked.com an intresting website. you guys can follow it on twitter... so here is it...huhuhu enjoy k...
Here's an effect so seamless that you probably never gave it a second thought during the 27-hour runtime of the Lord of the Rings trilogy: the fact that Elijah Wood and the other actors playing hobbits are not in fact three feet tall.
The camera takes off ... a few feet.
Ah, but who cares, right? With CGI, you can probably just click on an actor and tell the computer to shrink him by 50 percent and you're done. Right?
"Bam. Hobbits. Give me 20 minutes and a chimp and I'll give you King Kong."
Not if you don't want it to look like shit. It's one thing if the actor is just standing next to the normal-size characters in a field, but at various points in the trilogy, you see Gandalf grab the tiny Frodo, hug him, ride on the same carriage with him and sit down at the same table. To pull that off Peter Jackson, needed a buffet of effects techniques ranging from simple to insane.
Sometimes it was as easy as using a child in a Frodo wig shot from behind ...
... or just compositing the actors together from different shots, or digitally sticking Frodo's face onto a tiny double. But the coolest effects didn't involve any computers or green-screen trickery at all. It's called "forced perspective."
Or Hobbitvision.
The idea is that you put one actor really far from the camera and the other one really close to the camera, then shoot at such an angle that it appears they are next to each other and that one of them is really big and the other really small. Which sounds simple, until you realize that you need to build everything on the set so that the actors can interact with it at the same time while hiding the fact that they're far away from each other.
The simplest example is with Gandalf's cart. In the movie, you see them sitting side by side ...
... but the real cart is built so that if the camera is stuck in that spot, it hides the fact that Frodo is actually sitting about four feet behind Gandalf, with Ian McKellen's body hiding where the bench is split:
But the complication comes when you realize that this works only if the camera remains perfectly still. So any shot where the camera moves around has to involve a computer, right? Nope. In scenes like this one, where they share a table ...
... they are actually sitting at two different tables, one human-sized and one hobbit-sized ...
... that are made in such a way that each piece slowly turns with the camera, so that the whole time, they appear to be one simple table, shifting with the perspective of the viewer. This required that the camera be put on a motion-control rig and half of the set be put on another rig that completely counteracted the movement of the camera. So when the shot moved, the set, props and even the actors moved accordingly (yes, while McKellen was trying to stay in character as Gandalf, he was on a stool that was slowly scooting him around the room).
"It's a little bit trippy when you've had too much pipe weed."
Take a moment to think about the crew that put that together, knowing the final goal was for you to never notice it.
so that all, you can see more about this and all other movies at this link
P/S cant wait to watch The Hobbit... yeah!!!!!
