FaceTime Camera Images Look Poor on New Macbook Pro Retina Models

I received my new 2012 Macbook Pro Retina display model yesterday. When doing Facetime last night, others on the other end were commenting how poor the image coming from my end looked. Then I tried it on my iphone 4S and it was amazing how much better the picture of me looked on the phone versus the macbook. Today, I went to the Apple store to compare my new computer to the Retina display models on the display. Their camera images honestly didn't look much better than what I have on mine (but for example, the new Macbook Air's images look much more realistic). Why is this? How can the HD Facetime camera in the Macbook Pro produce less realistic images than the lower resolution iPhone 4S or Ipad cameras? Any help or insight you could share would be appreciated.

Thanks!
