TIP #22: Take a test shot before you put the little people in place.
Select all your camera settings and take a test shot before you call little people to be in the picture. You will have much more success if you focus on your camera settings when little children are not waiting for you. For example, look at these pictures below. First, I took a moment to set up my camera for my lighting in the particular setting I wanted to get a picture of six little kids in. Then, I called the kids in and took their picture. They only lasted half of a minute really anyway, right? So make the most of it. :)
