Define "image capturing" for me.

Your new Mac has everything, including software, that you will need for image capturing.
iMovie to capture live video from an external camera,
iPhoto to import still pictures from a digital camera
Image Capture to import pictures from just about any connected picture producing device.
Photo Booth to take and store still or moving pictures from the iSight camera (Built into all iMacs)

What does this software do, how are the images put on your computer and what device is used to initially capture the image before transfer?
