Blur With Panning Trick

I wanted to recreate the effect of a camera "focusing in" on a mug on the window. So, I created a series of steps to make the animation....

Here's the steps:

1. Create two copies of the scene, and use gaussian blur filter to blur one....

2. Create a layer mask on the blurred layer, i used a circular gradient to get a "bullseye" effect.

3. unlink the mask from the blurred image.

4. Transform the mask to enlarge it to three times the size of the image.

5. Create new frames as you "pan" the mask through the scene.... the mask reveals the crisp image as you pan....!!!!!

6. I used "tweening" to create most of the movie- it worked!!

Heres the movie so far!
