Raspberry Pi Camera Module: Still image capture
In The MagPi #129 we introduced libcamera-still which allows us to capture still images. But it also has many more options controlling how it captures images, and the file formats and available image encoders. We’ll discover some of those in this tutorial. For now, we shall continue to assume that you have your keyboard and a monitor plugged directly into your Raspberry Pi.
