Before the picture taking begins we have a process we do each morning.  That involves turning on the camera lights, the camera, and the computer.  We wait about 15 minutes before we actually start so the lights have time to be warmed up and are putting off enough light to take the pictures.  

First the camera is focused.  We have a special target
we use to check the focus.

The lens on the camera has little arrows (we put
them there) to keep our focus in the same area.

Next we check to make sure that the light is
bright enough to get a good picture.
You can see the monitor which shows us
if there is a problem.  Once it is right a prompt will
tell us that we can go to the next step.
