I got this camera as a gift at Christmas 2008. My first two sets of photos (using iA) were excellent. then I experimented as I tried to learn the features using the manual. Since that time my pictures, which are mainly people, are very poor. They look out of focus and have a fringe round them. I am very busy at work and do not have time to study the manual. can anyone tell me how to get the camera back to default settings as easily as possible. Thank you!
