3. Taking Still Photos with rpicam-still
   Capture JPEG and PNG stills with chosen size, quality and delay. · Lab: Take the same scene at three resolutions and compare file size and detail.
4. Recording Video with rpicam-vid
   Record clips of a set length and wrap them into MP4 with ffmpeg. · Lab: Record a ten-second clip, convert it to MP4 and play it on another computer.
5. First picamera2 Script: Preview and Capture
   Start the camera from Python and save an image. · Lab: Write a picamera2 script in a venv that shows a preview for three seconds and captures a JPEG.
6. Resolution, Sensor Modes and File Size
   Relate sensor mode, field of view and storage use. · Lab: Capture in each sensor mode and fill in a table of field of view, frame rate and bytes.
7. Focus, Exposure and White Balance for Beginners
   Fix the three most common causes of a bad picture. · Lab: Photograph a label at 10 cm and at 2 m with autofocus, then lock exposure for a backlit scene.

   Capture frames at an interval and build a video from them. · Lab: Shoot one frame every ten seconds for an hour and render a 30 fps clip.
9. Triggering Photos with a Button and a PIR Sensor
   Combine gpiozero events with picamera2 capture. · Lab: Take a photo on each button press, then on each motion event with a cool-down period.
10. Organising, Naming and Transferring Captures
    Keep captures sorted by date and stop the card filling up. · Lab: Save into dated folders, delete the oldest when free space runs low and rsync the rest to a laptop.
