Chapter 8 The Raspberry Pi Camera Module 197THE OFFICIAL RASPBERRY PI BEGINNER’S GUIDE
The Camera Module comes with a small piece of blue plastic covering the lens, in order to
protect it from scratches during manufacturing, shipping, and installation. Find the small flap
of plastic and pull it gently off the lens to get the camera ready for use.
Connect the power supply back to the Pi and let it load Raspbian. Before you can use the
camera, you’ll need to tell the Pi it has one connected: click the raspberry icon to load the
menu, choose the Preferences category, and click Raspberry Pi Configuration. When the tool
has loaded, click the Interfaces tab, find the Camera entry in the list, and click on the round
radio button to the left of ‘Enabled’ to switch it on (Figure 8-3). Click OK, and the tool will
prompt you to reboot the Pi. Do so and your camera will be ready to use!

ADJUSTING FOCUS
The Raspberry Pi Camera Module is usually supplied with a
small plastic wheel. This is designed for adjusting the focus of the
lens. While the factory-set focus is usually perfect, if you’re using
your camera for very close-up work you can slide the wheel over
the lens and gently twist it to adjust the focus manually.
