Thanks for replying so quickly. I have reset my camera but the problem still exists. I brought my camera back to where I purchased it and the technician said that he thought that there was something wrong in the AUTO setting with the light. I also brought my camera to a professional local photographer who uses Canon exclusively and he said that he believed that the computer in the camera was not programmed properly. He noticed that on one of my shots where the wall is yellow and it is reflecting onto my daughter's face and making it yellow (in AUTO mode and once in Program mode) that the ISO was very low and the shutter speed was very low. He found this quite bizarre.
I have not yet taken pictures outside. My friend has the very same camera (bought 2 weeks before mine) and her outdoor shots were beautiful. When she came to my house to see if her camera had the same results as mine she certainly did. We took shots of our daughters and the white shutters in the background became yellow. This did not happen when I tried the same shot with my HP Photosmart camera. The shutters remained white. She does get that yellow hue in her shots as well.
In my house I do have fluorescent lighting in the basement where my walls and my daughters' faces turned yellow (even when using the fluorescent setting). Upstairs I have ordinary lightbulbs. What bothers me is that my HP never gave me this problem and I have been taking pictures in my home with my HP for 5 years now. Now with the Canon, you have to take a shot 4-5 times before it comes out without either a blur or yellow. Putting it on Program seems to help sometimes but that makes shots blurry.
As you can see I am quite frustrated. It shouldn't be this difficult to get a good shot. I hope that this gives you more info as to what is happening.
Thanks for your time.
