Why hire a Photographer?

I am currently on a mission trip to Kansas. Our group of 14 arrived here at the Haskell University for Native Americans and wanted to get a group photo. Of course I brought my camera with me, so I pulled it out and my husband asked on of the men who were there to greet us if he would take the photo. (No tripod with me) So, I got everyone in formation for the photo, zoomed in just right and showed him where to stand and how to work the camera. He took two photos. BOTH were crooked! This is why you should never leave photography to your friend or your relative. A photo that you can never "re-do" will likely turn out badly, if it turns out at all.
