-==== Live Capture ====
-<color #ed1c24>IMPORTANT!</color>
-After failing to capture images, I discovered this little gem: gphoto2 is configured by default to capture files to your camera's RAM. You need to set it to capture to the SD Card.
-\\
-\\
-Type in the following from the terminal.
-\\
-    gphoto2 --get-config capturetarget
-\\
-You will most likely get the following:
-\\
-\\
-Label: Capture Target
-Type: RADIO
-<color #ed1c24>Current: Internal RAM</color>
-Choice: 0 Internal RAM
-Choice: 1 Memory card
-\\
-\\
-Here we can see that the capture target is set to <color #ed1c24>Current: Internal RAM</color> and we want it to be <color #ed1c24>Memory Card</color>
-\\
-\\
-Enter the following:
-\\
-    gphoto2 --set-config capturetarget=1
-\\
-Now when we check, we should get the following:
-\\
-Label: Capture Target
-Type: RADIO
-<color #ed1c24>Current: Memory card</color>
-Choice: 0 Internal RAM
-Choice: 1 Memory card
-\\
-\\
-Now we are set to record captures to the <color #ed1c24>Memory Card</color>
-\\
-\\
-Now, this depends on your camera, and whether gphoto2 supports it on your model. To get the capabilities of your camera, use the following command:
-\\
-    gphoto2 --summary
-\\
-Now on my 700D, I see the following:
-\\
-<file>
-Camera summary:
-Manufacturer: Canon Inc.
-Model: Canon EOS 700D
-  Version: 3-1.1.3
-  Serial Number: 46ff2aa38fba41f88d84eccb8eba8ada
-Vendor Extension ID: 0xb (1.0)
-Capture Formats: JPEG
-Display Formats: Association/Directory, Script, DPOF, MS AVI, MS Wave, JPEG, CRW, Unknown(b103), Unknown(bf02), Defined Type, Unknown(b104), Unknown(b105)
-Device Capabilities:
-        File Download, File Deletion, File Upload
-        No Image Capture, No Open Capture, Canon EOS Capture, Canon EOS Shutter Button
-Storage Devices Summary:
-store_00020001:
-        StorageDescription: SD
-        VolumeLabel: None
-        Storage Type: Removable RAM (memory card)
-        Filesystemtype: Digital Camera Layout (DCIM)

-        Maximum Capability: 31678529536 (30211 MB)
-        Free Space (Bytes): 31375130624 (29921 MB)
-        Free Space (Images): -1
-Device Property Summary:
-Property 0xd402:(read only) (type=0xffff) 'Canon EOS 700D'
-Property 0xd407:(read only) (type=0x6) 1
-Property 0xd406:(readwrite) (type=0xffff) 'Unknown Initiator'
-Property 0xd303:(read only) (type=0x2) 1
-Battery Level(0x5001):(read only) (type=0x2) Enumeration [100,0,75,0,50] value: 100% (100)
-</file>
-\\
-Importantly, I see the following section:
-\\
-\\
-<color #ed1c24>Device Capabilities:</color>\\
-\\
-File Download, File Deletion, File Upload\\
-<color #ed1c24>No Image Capture</color>, No Open Capture, Canon EOS Capture, Canon EOS Shutter Button\\
-\\
-So my 700D does not allow gphoto2 to capture files. There are two methods that you can use to try, and they are:
-\\
-    gphoto2 --capture-image
-    gphoto2 --capture-image-and-download
-\\
-<color #ed1c24>gphoto2 --capture-image</color> takes a photo and stores it on the SD card.
-<color #ed1c24>gphoto2 --capture-image-and-download</color> takes a photo and stores it on the SD card and downloads it.
-\\
-\\
-On some cameras the <color #ed1c24>takes a photo and stores it on the SD card</color> takes the image, but does not store it on the SD card (like on my 700D) so you can use <color #ed1c24>gphoto2 --capture-image-and-download</color> and the camera will take the photo and gphoto2 will download it, but it will still not be store on the SD card (does not work on my 700D)
-\\
-\\
-So in summary, I have been able to download files from my camera(s) but not capture from them. So I can make a decent backup solution using gphoto2, but not an intervalometer.

-Cameras tested so far:

-Canon EOS M (the original)
-Canon EOS 550D
-Canon EOS 700D
