3.5.1 Lens Focusing

Out of the box, the camera focus is set at infinity, but it does have a manual focus. Unfortunately, the camera lens is very small, which made focusing the camera on the rulers a tedious task with having to repeatedly take pictures and make small adjustments back and forth, as shown in Figure 17.
