Shooting a photo and the imediately seeing it on a large monitor is a feature I’ve always wished. I don’t say live view on a display but instant copy and display would suffice. And actually, as I found out, it’s quite easy to achieve on Ubuntu Linux (10.04) with a Canon D450.
Required software
Make sure gphoto2 and geeqie (former gqview) is installed. An apt will do the trick:
sudo apt-get install gphoto2 geeqie
Scripts
I’ve written 2 scripts. The first one does the tethered capture and the second does the display of the image using geeqie
capture.sh:
#!/bin/bash
#capture.sh script
#the capture-tethered only works if a capture-image has been issued first
#so capture an image first
gphoto2 --capture-image
#do the actual capture-tethered
gphoto2 --capture-tethered --hook-script $(dirname $0)/capture1.sh
capture1.sh:
#!/bin/bash
#capture1.sh script
if [ "x$ACTION" = "xdownload" ]; then
geeqie --remote $ARGUMENT &
fi
You just need to create these 2 files in a folder of your choice and then make them executable
chmod u+x capture.sh capture1.sh
Usage
- Plug the camera in
- It will be detected and mounted automatically by ubuntu. Unmount it to allow gphoto2 to lock it.
- start the script capture.sh It will save files in the form capture0001.jpg in the working directory each time you shoot a photo then display them in geeqie. Note: the photos will be downloaded and deleted from the camera.
- press Ctrl+C to stop the process
