"},{"location":"setup/camera_setup/","title":"Camera Setup","text":"

The photobooth app supports cameras utilizing multiple backends:

Two backends can be used simultaneously in hybrid mode. The first backend is used as main backend to capture high quality still images. The second backend is used as live backend to stream video preview only.

Note

After changing config, the app needs to be restarted manually.

If you need help setup a specific camera, start a new discussion on github.

"},{"location":"setup/camera_setup/#raspberry-csi-camera-modules","title":"Raspberry CSI Camera Modules","text":"

Camera modules are supported using picamera2 based on the new libcamera stack. Autofocus camera modules are supported.

The app is tested with following devices:

"},{"location":"setup/camera_setup/#camera-module-3","title":"Camera Module 3","text":"

The latest Camera Module 3 is probably the best camera module to use in the photobooth. It supports fast autofocus and comes with native driver in the Raspberry Pi OS.

Ensure the camera is working properly using the libcamera stack:

libcamera-hello\n

If it does properly open the camera, the photobooth app can use it also. If some errors come up, try to fix the camera setup before start using it actually. Find installation instructions directly at the raspberry pi foundation.

Now finish setup:

"},{"location":"setup/camera_setup/#camera-modules-12hq","title":"Camera Modules 1/2/HQ","text":"

All other camera modules from the Raspberry Pi ecosystem work the same way as the latest camera module 3. They usually come with lower image quality and do not have autofocus. Due to this other camera modules are not recommended for use as main camera. You might consider to use them only for livestream preview.

Setup is the same as for camera module 3 but with different resolution and no focuser module enabled.

"},{"location":"setup/camera_setup/#arducam-imx519","title":"Arducam imx519","text":"

Sony's imx519 sensor used in Arducam's imx519 camera module is supported by the Raspberry Pi OS natively since about March 2023.

This means the module can be used with or without installing Arducams custom driver packages:

Now finish setup:

"},{"location":"setup/camera_setup/#other-third-party-camera-modules","title":"Other third party camera modules","text":"

In principle every camera supported by libcamera / picamera2 would work. Since the cameras do not come with native support of the Raspberry Pi OS using them could be troublesome and it's untested. Start a discussion if there is a camera not working properly.

"},{"location":"setup/camera_setup/#dslr-via-gphoto2-linux","title":"DSLR via gphoto2 (Linux)","text":"

The app is tested with a Canon 1100D. In general all gphoto2 supported cameras can be used. If the camera supports liveview a stream is created and being used as preview in the app. If the camera does not support liveview, you might want to consider setup the app in hybrid mode. Main camera would be the DSLR to take high quality images, the livestream is captured from a secondary backend. As secondary backend most suitable is a webcamera or raspberry pi camera module.

Now finish setup:

DSLR cameras of different manufacturer may behave differently. There are some settings that might need to be adjusted if autofocus is slow or preview cannot be generated. Tinker with available settings until it works properly. If you run into trouble, create a new issue in the tracker.

"},{"location":"setup/camera_setup/#webcam","title":"Webcam","text":"

USB-webcams are integrated via two backends:

On Linux prefer v4l2 backend because it is more efficient in directly streaming MJPG data instead image frames like the opencv2 implementation.

To use the webcam choose opencv2 or v4l2 as backend.

Both backends use a camera device index to open the camera. To find which indexes are available on your system issue the following commands.

check v4l2 indexes:
python -c \"from photobooth.services.backends.webcamv4l import *; print(available_camera_indexes())\"\n
check opencv2 indexes:
python -c \"from photobooth.services.backends.webcamcv2 import *; print(available_camera_indexes())\"\n

The command returns an array of indexes for which a webcam was detected.

Now finish setup:

"},{"location":"setup/camera_setup/#hybrid-dslr-and-second-backend-to-stream","title":"Hybrid: DSLR and second backend to stream","text":"

The app supports simultaneous use of two backends at the same time. This is useful to grab high quality pictures from a DSLR camera via gphoto2 and livestream from a webcamera or picamera module. Hybrid mode allows for live preview even if the DSLR camera is not capable to stream preview video.

In hybrid mode, the main backend is used for still images, the live backend for video streaming. To enable hybrid mode: - configure main backend as normal - also configure live backend.

If a live backend is set, it is requested for video preview instead of the main backend.

On Linux printing is realized with CUPS software. The cups webinterface is available on http://localhost:631/printers/ usually. The link only works from the Linux system itself, it's not available in the local network. Installing a printer is very individual to the specific printer and the setup. Try to install on your own. In the end, make sure the following command prints a photo. Instead of {filename} point to some image on the computer for testing.

Following is an example to print. Set the command in the app. {filename} is replaced by the .jpg image to print when the job is run.

lp -d PRINTER_NAME_HERE -o landscape -o fit-to-page {filename}\n

If you use other commands, that work better in your installation, let me know in GitHub Discussions.

The photobooth app supports cameras utilizing multiple backends:

Two backends can be used simultaneously in hybrid mode. The first backend is used as main backend to capture high quality still images. The second backend is used as live backend to stream video preview only.

The latest Camera Module 3 is probably the best camera module to use in the photobooth. It supports fast autofocus and comes with native driver in the Raspberry Pi OS.

Ensure the camera is working properly using the libcamera stack:

libcamera-hello\n

If it does properly open the camera, the photobooth app can use it also. If some errors come up, try to fix the camera setup before start using it actually. Find installation instructions directly at the raspberry pi foundation.

Now finish setup:

All other camera modules from the Raspberry Pi ecosystem work the same way as the latest camera module 3. They usually come with lower image quality and do not have autofocus. Due to this other camera modules are not recommended for use as main camera. You might consider to use them only for livestream preview.

Setup is the same as for camera module 3 but with different resolution and no focuser module enabled.

If the camera supports liveview a stream is created and being used as preview in the app. If the camera does not support liveview, you might want to consider setup the app in hybrid mode. Main camera would be the DSLR to take high quality images, the livestream is captured from a secondary backend. As secondary backend most suitable is a webcamera or raspberry pi camera module.

Now finish setup:

DSLR cameras of different manufacturer may behave differently. There are some settings that might need to be adjusted if autofocus is slow or preview cannot be generated. Tinker with available settings until it works properly. If you run into trouble, create a new issue in the tracker.

USB-webcams are integrated via two backends:

On Linux prefer v4l2 backend because it is more efficient in directly streaming MJPG data instead image frames like the opencv2 implementation.

To use the webcam choose opencv2 or v4l2 as backend.

Both backends use a camera device index to open the camera. To find which indexes are available on your system issue the following commands.

check v4l2 indexes:
python -c \"from photobooth.services.backends.webcamv4l import *; print(available_camera_indexes())\"\n
check opencv2 indexes:
python -c \"from photobooth.services.backends.webcamcv2 import *; print(available_camera_indexes())\"\n

The app supports simultaneous use of two backends at the same time. This is useful to grab high quality pictures from a DSLR camera via gphoto2 and livestream from a webcamera or picamera module. Hybrid mode allows for live preview even if the DSLR camera is not capable to stream preview video.

In hybrid mode, the main backend is used for still images, the live backend for video streaming. To enable hybrid mode: - configure main backend as normal - also configure live backend.

If a live backend is set, it is requested for video preview instead of the main backend.

On Linux printing is realized with CUPS software. The cups webinterface is available on http://localhost:631/printers/ usually. The link only works from the Linux system itself, it's not available in the local network. Installing a printer is very individual to the specific printer and the setup. Try to install on your own. In the end, make sure the following command prints a photo. Instead of {filename} point to some image on the computer for testing.

Following is an example to print. Set the command in the app. {filename} is replaced by the .jpg image to print when the job is run.

lp -d PRINTER_NAME_HERE -o landscape -o fit-to-page {filename}\n

If you use other commands, that work better in your installation, let me know in GitHub Discussions.

Info

You might want to update to more recent driver packages. See following guide: https://www.peachyphotos.com/blog/stories/building-modern-gutenprint/ Also you might need a ppd file. Here is one for Canon Selphy CP1300 that works.
