substituting a face in a picture

I want to find a program that will allow me to repalce a face in a picture,
e.g. on a magazine cover. I have done this using Adobe Photo Shop 7 but
was recently in Florida at Universal Studios. There I saw a system that
allowed them to take a person's picture using a video camera and blue
screen. The magazine cover was placed on the screen and the face was
blank. They would have the person adjust their head to situate their face
in the blank area. They would then snap the picture and the software would
blend the face into the pciture.

My question is where can I find this kind of software? I have searched the
net and have had no success. Any help would be greatly appreciated.
Thanks.

The Blue background was the clue - This is called the ChromaKey. As far as I
know this is a video only technique - the Chroma Key system takes two video
feeds - say A and B. A is the picture of you with the blue BG and B is a
video of the magazine cover. The system switches on your your picture
except when it detects the blue ChromaKey- in the BG - then it switches to
the other B feed. The resultant video image shows you with the magazine
cover substituted for the blue - the printout was then just a screen dump of
the composite video image. It was used all the time in real-time video to
simulate back projected images for newcasters on TV .

The photographic equivalent process is to use Photoshop although you haven't
always got a really monochromatic BG that you can use as a ChromaKey.

Hope this helps

Corel KnockOut does this. You can remove the blue screen from the
background of a photo, leaving only whatever is in the foreground. You
can then plug the foreground into any background you want. Works
extremely well.

Extensis MaskPro does essentially the same thing, although I prefer
KnockOut.

You can do it in a less precise way directly in Photoshop, too.

You could also make a transparent "hole" in the scene, and then move
the face in under it.

That's the approach of this software, the modern-day equivalent of
sticking your head through a board for a seaside photo!

Or you could line the pictures up, and use a transparency mask to
blend them
