====== Basic Intervalometer ====== Jun 2017 \\ \\ ---- \\ So here is a command line to use gphoto2 as a basic intervalometer. You can type this in at the terminal, or you could use a python script to generate this command line based on user input. \\ \\ gphoto2 --interval=10 --frames=10 --capture-image-and-download \\ So in this example, we are going to capture 10 frames, at an interval of 10 seconds, and download each file. \\ Time-lapse mode enabled (interval: 10s). Capturing frame #1/10... Waiting for next capture slot 9 seconds... New file is in location /store_00020001/DCIM/100CANON/IMG_5934.CR2 on the camera Downloading 'IMG_5934.CR2' from folder '/store_00020001/DCIM/100CANON'...

It can be see that after the image is downloaded, it is deleted also. If you don't want the files deleted, use the following syntax. \\ gphoto2 --interval=10 --frames=10 --capture-image-and-download --keep \\ Here are the 10 files I captured \\ IMG_5934.CR2 IMG_5936.CR2 IMG_5938.CR2 IMG_5940.CR2 IMG_5942.CR2 IMG_5935.CR2 IMG_5937.CR2 IMG_5939.CR2 IMG_5941.CR2 IMG_5943.CR2 \\ WARNING!!! If you pick a short interval (say 3 or 4 seconds) then the Raspberry Pi may not be able to write the files fast enough, and you may end up with dropped frames (if you use the --keep switch, they will still be on the camera memory card though). \\ \\ If you need a relatively short interval, then just use the following syntax to capture the files, then download them at the end of the capture. \\ gphoto2 --interval=3 --frames=10 --capture-image \\ Here you can see the files are captured, but not copied or deleted (you don't have to use the --keep switch if you are not downloading at the same time). \\ Time-lapse mode enabled (interval: 3s).
