Our first try resulted in my seeing and hearing her perfectly, while she could hear me perfectly but could only see a poor video. Cleaning the screen over the built-in cameras didn't help. When I got home, we Skyped each other from different parts of the house so I could see what she was describing. I, using the iMac, heard her perfectly, but the video quality was pixelated and blurry. She, using the MacBook Pro, could hear and see perfectly. If she waived her hand in front of the MacBook's camera, the video on the iMac would get dramatically worse and even freeze for a half second. It appears there's some problem causing pixelation and blurring between the time the light enters the lens of the camera on the MacBook Pro to the time the video image is displayed on the iMac. Is there anything I can do, like changing configuration settings or something else, to make the video on the iMac as good as the video on the MacBook Pro?
