Canon EOS 650D takes 4 shots instead of one
Hi, I have attached my 650D DSLR to a RPi 4, and for each and every photo it takes 4 shots (saving only one...) but it keeps taking 4 shots. So when we click on "4 shots"... well it the shutter takes 4x4 ... 16 ! shots. That "problem" is only found with pibooth. No problem whastoever with windows. I've tried PhotoboothProject.github.io too, same Pi, same DSRL, works as it should : just one shutter/shot per photo. Any help would be greatly appreciated.
Thanks a lot.
My bad... It seems to be caused by the preview... Is there a way to only have 1 shutter preview, normal count-down and picture taken ? instead of 4 shutter previews ? Or maybe a live preview ? or no preview at all ?
Thanks.
It is indeed linked to the preview. We didn't find a way to get video through Gphoto2 so we had to implement this fallback mechanism. My best advice is to use pibooth in hybrid mode: a Pi camera for the preview and the DSLR for the photo.
I've stumbled into the same issue and it was caused by OpenCV apt pkg using an old gphoto2 library (rather than the one build locally)
I would recommand uninstalling OpenCV using apt and installing it manually using pip
I @supercairos
Thanks for the feedback.
During a long time, it was not possible to install OpenCV with pip on PiOS. Is now possible? I could modify the setup to install it automatically using pip.
I believe so, I've used opencv-python
But I might be in a special setup as I'm using a Rpi 4 with the 64bits and Debin Bullseye
Actually looking at the precompiled files, it seams there is no 32bits version for OpenCV python binding: https://pypi.org/project/opencv-python/#files
i've been trying with both openCV via apt and pip on Rpi 4 64bits Bullseye
the one installed with apt allow me to start pibooth, but then i get an oups something went wrong. the one installed with pip doesn't start because i cannot find my canon 650D
Is there a way to get the image of a working version ? or explain the steps you did @supercairos ? that would be awesome
Hi @adonno,
I actually don't remember the proper steps, but I do remember that I built gphoto from sources. But in order to load it properly into PiBooth, you need to properly remove the apt version before (it is sometime installed by default).
Maybe if you have some error logs, I can help troubleshoot them...
In order to install GPhoto, I've used:
wget https://raw.githubusercontent.com/gonzalo/gphoto2-updater/master/gphoto2-updater.sh
wget https://raw.githubusercontent.com/gonzalo/gphoto2-updater/master/.env
chmod +x gphoto2-updater.sh
sudo ./gphoto2-updater.sh
I'll leave tonight for 3 days but i'll come back with logs when i'm back thank you.
Can't wait to get it finally working and to start adding hardware buttons.
In order to install GPhoto, I've used:
wget https://raw.githubusercontent.com/gonzalo/gphoto2-updater/master/gphoto2-updater.sh wget https://raw.githubusercontent.com/gonzalo/gphoto2-updater/master/.env chmod +x gphoto2-updater.sh sudo ./gphoto2-updater.sh
Yup did that it's also in their doc
Check that the Gphoto PiBooth is loading is really the built version and not a PKG version.
A gnome picture utility is also using Gphoto so it's usually installed by default on rpi4...
hi i'm finally back from vacation Like i said I installed the PIP version and have tried with legacy on and off from the raspi-config
If I try with a webcam it works and the Camera is recognised on the PI since it shows the SD card

Can you print the version of Gphoto ?

since it was working for you on bullseye i tried to replicate your setup

Maybe try the RasPi Bookworm version (Debian 12) aarch64 ? It's the one i've used.
Also, as soon as it's installed, uninstall the gphoto2 & libgphoto2 packages and build them from source.
You should have version 2.5.31 or above listed as libgphoto2 version
You can see here the version of the software It's building from source: https://raw.githubusercontent.com/gonzalo/gphoto2-updater/master/.env
Glad it worked! On my camera (700D) putting it on video mode gave a much better frame-rate than in picture mode.
I haven't tried on a pi5 (yet) but I didn't felt it was the RPi 4 that was limiting the camera fps.
Would love some feedback on a pi5 tho :)
It worked as a charm on a pi 5
now that i have both working i will test the speed difference regarding the frame-rate, i'm using a webcam for previews and it works like. charm actually, much faster pictures since it doesn't need to open /close the mirror for previews. Only point now is to find a webcam that has the almost same zoom level as the canon lens i'm using
