+So here is a command line to use <color #22b14c>gphoto2</color> 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=30 --frames=120 --capture-image-and-download
+    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.
+\\
+<file>
+Time-lapse mode enabled (interval: 10s).

+Downloading 'IMG_5936.CR2' from folder '/store_00020001/DCIM/100CANON'...
+Saving file as IMG_5936.CR2
+Deleting file /store_00020001/DCIM/100CANON/IMG_5936.CR2 on the camera

+etc..
+</file>
+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
+\\
+<file>
+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
+</file>
+\\
+<color #ed1c24>WARNING!!!</color> 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).
