Taking Your First Picture

Now that your camera is set up, let’s take a picture.

Using The Command Line To Capture An Image

Open your terminal.
To capture an image with the Raspberry Pi Camera Module, type the following command:

bash raspistill -o image.jpg

This command will take a still image and save it as image.jpg in your home directory.
To use a USB camera, you may need to use tools like fswebcam or gstreamer for image capture.

Recording Video And Streaming

Beyond still images, your camera can record video and even stream footage live.

Recording Video With The Raspberry Pi Camera

To record a video, use the following command in your terminal:

bash raspivid -o video.h264 -t 10000

Here, the -t flag stands for the duration in milliseconds (10 seconds in this case).

Live Streaming Your Camera Feed

For advanced usage, you can set up your camera for live streaming. Popular methods involve using MJPG-Streamer for live streaming:

Install Dependencies:
Update and install MJPG-Streamer:

bash sudo apt update sudo apt install mjpg-streamer

Start Streaming:

bash sudo mjpg_streamer -i "/usr/lib/mjpg-streamer/input_uvc.so -r 640x480 -f 30" -o "/usr/lib/mjpg-streamer/output_http.so -w ./www -p 8080"

Access the Stream: Open a web browser and enter http://<YourPiIPAddress>:8080 to view the live feed.

Exploring Advanced Features

Raspberry Pi cameras come with various settings and features that allow for more sophisticated photography.

Configuring Camera Settings

You can adjust different settings in your capture commands, such as:

Resolution: Use the -w for width and -h for height.
Quality: Set the quality of your images with the -q option (0-100).
Brightness and Contrast: Adjust these using the -br and -co flags.

Using Python To Control The Camera

For those looking to automate and script camera operations, Python is an excellent choice. The picamera library allows easy integration with Python scripts.

Install Picamera:

bash sudo apt install python3-picamera

Example Python Script:

“`python
from picamera import PiCamera
from time import sleep

camera = PiCamera()

Start the camera preview

camera.start_preview()

Wait for the camera to warm up

sleep(2)

Capture an image

camera.capture(‘image.jpg’)

Stop the camera preview

camera.stop_preview()
“`

Save this script and execute it to take photos programmatically.
