How to Pan and Zoom Your iSight
by Ken Aspeslagh
Using the Zoom and Pan feature of iGlasses 2.0, you can virtually change your camera angle in order to center yourself in the video frame. This is especially useful with the built-in iSight since it cannot be physically aimed without moving the entire Mac.
I find that in most situations, the built-in iSight on my MacBook Pro aims too high, showing too much ceiling and not centering me vertically in the shot. To fix this problem, I use iGlasses to quickly get a perfect head shot for my video chat. Once I get the perfect zoom and pan setting, it can be saved and quickly recalled the next time I need it. I've put together some instructions for doing this yourself.
Doing It Yourself
To manually adjust your angle, open the iGlasses window, and click the camera icon to open the advanced settings. You'll see a small pull-down menu listing all of iGlasses's effects. One of the options is "Zoom and Pan".
Select the Zoom and Pan option and you should see a zoom slider and a thumbnail of your camera image. Slide the slider to zoom in and out. If you're zoomed in, you can then move the zoomed section of the image by dragging it right, left, up or down.
You can also control this screen using the Apple Remote (The little white remote that came with your Mac.) When the Zoom and Pan screen is active, the remote will let you zoom in and out using the Play (middle) button to zoom in and the Menu button to zoom out. The up, down, right, and left buttons will aim the shot.
To save your adjustments, pick Save Custom Preset from main iGlasses menu (the large pull-down) and type a name.
 
Animate Transitions
It might not be obvious what the Animate Transitions checkbox does. When you select a saved zoom setting from the iGlasses menu, you'll see the camera angle change in one of two ways. If Animate Transitions is checked, iGlasses simulates camera movements as if someone was controlling an actual camera. You'll see it zoom and tilt to get to the new setting. If Animate Transitions is not checked, the angle will jump directly to the new setting.
Simulating a Multi-Camera Shoot
It's possible to use this feature to do a simulated multi-camera shoot. Picture two people sitting in front of an iMac. Simply set up two preset zooms: A head shot of each person. By switching between these presets, you can make it appear that you have more than one camera.
