How to Use iSight
Although we tend to associate OSX's program Photo Booth with humorous pictures of our friends with stretched faces or dressed virtually as someone from a comic book, you can actually take semi-professional photographs of yourself, your friends, or your family with the built in iSight.
Before you can take semi-professional portraits with your Mac's iSight, you should know how to use your iSight. In case you aren't familiar with the feature and its companion program, Photo Booth, here's a quick how-to guide:
First, make sure your iSight is turned on; this should happen when you load up the Photo Booth application. If you want to use a special effect, such as x-ray, make sure you click that option before taking the picture. Finally, get ready to smile and press the red shutter button.
Now that you know how to use iSight and Photo Booth, it's time to take some pictures! Although most people use iSight to take pictures of themselves to put on social networking sites or for buddy list icons, you can take really nice, almost professional images of yourself, your friends, or your family with the Mac camera.
