I agree with you when we do photos for us, we capture the moments and we do not care much about how the photo looks like. Because looking at it we recall the event and our memories with it. But when the professional photogrpaher does it he looks with another eye and of course, there are many little changes that he would add to make the photo perfect. Looking at hte church I was impressed with architecture and hte stars I did not pay attention to the shadow but my attention was concentrated on the beautyf of the rails.
