U.S. Passport photo requirements are different to Swedish and European photo requirements. Any photographs that do not meet the specified requirements will be rejected. If your child is an infant, their eyes are not required to be open.
If you choose to submit digitized photographs, they must meet the requirements as listed above or they will be rejected. Some printers will produce an unacceptable photograph in which the dots are seen, or the image is grainy. Acceptable photographs are printed on high-quality photographic paper, have a continuous tone image that is very photo-like, and show the subject clearly in focus.
