TimeLapse with DSLR and RaspberryPi

You can use your RaspberryPi to create a perfect TimeLapse-System using Gphoto2. You can easy install it by typing following

sudo apt-get install gphoto2  

with

gphoto2 --auto-detect

you can see if and what camera is connected. Then (if you want to record on the SD Card) you have to check the „location“ of your memory card

gphoto2 --get-config capturetarget

the output should look like:

pi@raspberrypi:~ $ gphoto2 --get-config capturetarget
Label: Capture Target                                                          
Readonly: 0
Type: RADIO
Current: Internal RAM
Choice: 0 Internal RAM
Choice: 1 Memory card
END

Now we can set the capture target to the Memory Card with this command:

photo2 --set-config capturetarget=1

Now you can use following command to take pictures and save them direct to your SD Card

gphoto2 -–capture-image  

For timelapes I would recommend that you use the screen command to build a virtual terminal session and easy detach and attach this again

Now you can start your photograph session with this command.
-I defines how long you want to wait between the pictures
-F defines how many pictures you want to take

gphoto2 -I 20 -F 10000 --capture-image 

If you want to download the pictures to your Raspberry Pi’s SD card you have to use following:

gphoto2 --capture-image-and-download
