Hi, I went to take a picture with a professional photographer and thought it looked fine. When I got home, I noticed that Im a tiny bit tilted to the left, meaning from head to shoulders the whole image tilted to the left. It's hard to notice it but if you put a imaginary line in the middle of my chine, the line would not end up exactly in the middle of my forehead. Just the overall picture is tilted, even one of my shoulder is slightly higher than the other. There's this function in the website I use for cropping my image (picnik.com) that lets me tilt my picture, so I used it and now my picture is straight. Is this considered an alteration to the picture?
