Sorry if there is an obvious answer here. I recently received my T1i and everything has been fine up until today. Every photo I have taken has a tanish gradient which randomly changes locations. At first I thought it was the lighting and then I thought it had to do with settings on the camera. Then I thought maybe it was the SD card and after formatting and still getting nowhere I figured I would turn here for some advice. Here are some sample pics that kind of show whats happening here. I did not change any settings between these photos and these were taken after formatting the card. top bottom top middle - wall (a white wall at that, and yes I set the white balance appropriately) I am at a loss folks :sad anim: I can take 10 consecutive photos of the same subject on a tripod and that damn gradient is in a different location every shot. If I lived within 1 hour of a photo shop I would have already stopped by one and I do not have a phone to contact Canon. Should I just contact them online? I have a feeling that they will shrug it off and tell me to read the manual or that it is "user error." I suppose that is because I have had similar hopeless experiences with customer support in the past. Any info or advice is very much appreciated. Thanks for taking the time to read this.
