How to Take a Photo Using Raspberry Pi Camera Module

To take a photo using Raspberry Pi, connect the official camera module and enable it in raspi-config. Then use the libcamera-still command or Python code with picamera2 library to capture and save an image.

Syntax

Use the libcamera-still command to capture a photo from the Raspberry Pi camera module.

• libcamera-still -o filename.jpg: Takes a photo and saves it as filename.jpg.
• -t 0: Optional flag to keep the preview window open indefinitely.
• -n: Optional flag to disable the preview window.

Alternatively, use Python with the picamera2 library to control the camera programmatically.

bash

libcamera-still -o image.jpg

Example

This example shows how to take a photo using Python and the picamera2 library on Raspberry Pi. It captures an image and saves it as photo.jpg.

python

from picamera2 import Picamera2
import time

picam2 = Picamera2()
picam2.start_preview()
time.sleep(2)  # Wait for camera to adjust

picam2.capture_file("photo.jpg")
picam2.stop_preview()
print("Photo saved as photo.jpg")

Output

Photo saved as photo.jpg

Common Pitfalls

Common mistakes when taking photos with Raspberry Pi camera include:

• Not enabling the camera interface in raspi-config.
• Using old raspistill commands on newer Raspberry Pi OS versions where libcamera is required.
• Not waiting for the camera to warm up before capturing the image, causing dark or blurry photos.
• Incorrect camera connection or loose ribbon cable.

Always check camera connection and enable it before running commands or code.

bash

## Wrong way (old command, may not work):
# raspistill -o image.jpg

## Right way (new command):
# libcamera-still -o image.jpg

Quick Reference

Command/Code	Description
libcamera-still -o image.jpg	Capture photo and save as image.jpg
picamera2.capture_file('photo.jpg')	Python method to capture and save photo
sudo raspi-config	Enable camera interface under Interface Options
time.sleep(2)	Wait for camera warm-up before capture

Key Takeaways

Enable the camera interface in Raspberry Pi settings before use.

Use the modern libcamera commands or picamera2 Python library for capturing photos.

Wait a couple of seconds after starting the camera to get clear images.

Check physical camera connection if photos are not captured.

Avoid using deprecated raspistill commands on new Raspberry Pi OS versions.
