Hi,
In some scenes, the background is getting farther, and in the same time the
character is getting closer, without moving. how is that effect obtained ?
is the actor standing on a hidden mobile stage ? |

Hardware wise, it's like gradually increasing or decreasing the lens sizes,
like going from 35 mm (like you probably recognise rightaway) to like 60 or
100 mm or whatever, while at the same time you keep zooming on the subject,
so it isn't dragged along with "background" into a distance, or getting
closer along with the "background" when if the process in in reverse.
Making sense? Also not sure if i'm describing it that good in my english :)
Software wise, hehe.. that's more simple. Just make sure you have background
footage and your subject on seperate footage, and resize both. I'd say
slowly size up the subject footage (threatening) and size down the
background footage (this of course enhances the threatening effect of the
subject "getting closer".

Thanx for your detailed answer.
Now I think of another question:
The old visual effects consisting of changing the background had problems
with surfaces that weren't smooth (hair for example). How is that problem
slved now ? is it all about image resolution ?

No.
It is called a "Dolly Zoom" and is accomplished by zooming in while dollying
out, or vise versa. Is considered tacky but still done alot. I saw it in the
first lord of the rings.

the answer to the other question about the hair:
It is called "Keying" and usually involves a green or blue screen it is
still not perfect (what is?) but is best done with higher resolutions.
google search 'green screen' got:

It also called vertigo effect. Hitchcock used it the first time in that
movie. I m pretty sure he didnt invent it but at least he made it very
popular. |

Yes, some people (including me) know it as the "Hitchcock Zoom".

A few times, I've thought about how one would do the special effects for a
scientifically-realistic depiction of the effects of a spacecraft
approaching the speed of light. One of the weirder effects would be that
the space ship would actually contract in length in the direction of its
travel. (OK, a camera keeping up with the space craft would experience the
same effect and would be unable to detect it in the spacecraft, but let's
say we wanted to depict the concept rather than recreate what a chase camera
would actually see.)
For profile shots, a low-budget production might shoot the reflection off of
a flexible mirror.
But for nearly head-on shots, I thought it would be interesting to program a
motion-control rig for this type of "Hitchcock Zoom", to provide the
illusion the head end and tail end of the ship were both shifting toward the
middle. And then reverse it for decelerating down to non-relativistic
velocities, which would make the ship seem to stretch back out to normal.
I always thought this type of shot would be most striking on a ship design
that had a "head" with a long spine. Like the Klingon Battle Cruiser, or
the Discovery.
But nowadays, such a shot would probably be CGI from start to finish, where
the model actually /could/ contract in length, and look fine from any angle.
But then, I'd always thought it would be cool to cut back and forth between
the ship and interior sets, doing the same thing there, to where foreground
people and objects seem to be receding at the same time backgrounds people
and objects seemed to be shifting forward a bit. So there might still be a
need for such a "Hitchcock Zoom" motion-control program.

We should ask, critically and with appeal to the numbers, whether the
best site for a growing advancing industrial society is Earth, the
Moon, Mars, some other planet, or somewhere else entirely.
Surprisingly, the answer will be inescapable - the best site is
"somewhere else entirely."

Vertigo/Hitchcock/Dolly Zoom -- whatever you want to call it, it also
appears in "Matrix Reloaded" *as a purely digital creation*! IIRC, it
turns up just near the end of the freeway chase. It's pretty subtle,
but it's there. |

You pull the camera in closer, simultaneously decreasing the focal
length of your lense. In essence you're going from a normal lense to a
wide angle lense. Professional cinematographers have a chart for this.
Keeps the focus puller busy! |

It isn't resolved yet. Watch Titanic, where the stern is vertical and
Rose, Jack, and the cook/chef are hanging on. Watch their hair. |
