What do you call it when you have a still image, but...

have have part of it expanding/moving? I would show examples, but it's tough to find without knowing the name of the technique. I know how to do it (at least a crude way) but want to learn a little more about it.

For instance, there would be a picture of a girl standing in front of a tree. The girl would slowly expand in size but the tree and the background would remain the same size.

I'm not sure if this is the proper board to ask this question, but it seems to be the most relevant to my Q.
 
it's an after effects technique I think. they use 3d planes with the subject and background on different layers and have the 3d camera move in.
 
When the picture moves as if the camera is zooming in or panning it's called the Ken Burns effect - I know the effect you are referring to where for example a person appears separated from the background.

I've often wondered about that too. You can do it by using layers of the same image with the top layer using a mask around the object to separate and then expanding that object. But I often wonder why you can't see traces of the the image you've selected in the background below.
 
It is often done by layering the image, cutting the girl out in photo shop, key framing and expanding her size while leaving the BG untouched.
 
^ An effect the cameraman can take back from the post world with 3D cinematography! A motorized pull on the interocular distance of the two lenses can do the same effect! Whoo! Never been done yet (to my knowledge only the PoC has been 'pulled' mid shot), but it would do the same.
 
stateofmind, is this what you're talking about?

I believe it's done in AE mostly but I assume you could do it in any NLE as long as you have the picture divided into the various layers, it just might take longer than what it would with After Effects, the History Channel and Discovery use it a lot in their docs, when done right it's a really cool effect. I saw a comic book scene animated in this style a few months ago, very neat stuff

Well, you can do it that way, or in some cases you can do a tracking sort of shot with the 'cutout' foreground figure, and using some sort of cloning to fill in the places that the cutout hid from the original camera shot.

I've also got 'water' on a sea shore scene of my wife's parents on their honeymoon, where the water 'moves' by cutting out the water section of the image and with motion and fade between different layers of the same 'water' cutout, give the impression of waves and the water coming up on the beach.

The earliest version of this sort of thing that I tried was something of the Hitchcockian motion, where both the forground figure, and the back ground were just 'zoomed' at different rates and end sizes.

If this is what you are talking about it's actually a very easy effect in after effects. You roto out the subject of the photo and change its position on the z axis so that it's in front of the background. Then when you animate the position of the camera it mimics what real lenses do in terms of relative position to the camera, ie: things closer to the camera move less in relation to things farther away.
