It is possible that you have inadvertently set something that is causing the problem.
You should Reset the camera.
Look in your camera User Guide on page 53.
"Returning the Camera to Default Settings"
If that does not fix the problem, a question.
Does any of your outside pictures show this problem?
What type of lighting in your house?
(florescent - incandescent - other)
I was wondering if anyone could help me with this problem??? I bought a Canon Powershot SX30IS and as I played with it I noticed that my pictures on AUTO mode all contained a yellow hue colour. My beige walls became yellow. My daughters' faces were yellow etc.. My white shutters in my kitchen have become yellow in the pictures. My friend has the same camera and is experiencing the same problem. I would appreciate any suggestions that anyone would have. Thank you!
