+We can control the settings on our DSLR, again what can be controlled will vary between models. To get a list of items that can (maybe) control, you can use this command.
+\\
+<file>
+gphoto2 --list-config
+</file>
+Here is the listing that I get from my Canon EOS 700D.

+So for example, in this list we can see a setting entitled <color #ed1c24>/main/capturesettings/aperture</color> which indicates we can control the aperture on this DSLR.
+\\
+\\
+To see what the possible values for <color #ed1c24>/main/capturesettings/aperture</color> that <color #22b14c>gphoto2</color> supports, we can use the following syntax.
+\\
+<file>
+gphoto2 --get-config /main/capturesettings/aperture
+</file>
+\\
+The 700D DSLR I am using returns the following:
+\\
+<file>
+Label: Aperture
+Type: RADIO
+Current: 4.5
+Choice: 0 4.5
+Choice: 1 5.6
+Choice: 2 6.7
+Choice: 3 8
+Choice: 4 9.5
+Choice: 5 11
+Choice: 6 13
+Choice: 7 16
+Choice: 8 19
+Choice: 9 22
+</file>
+So we can see that the current aperture is 4.5 (probably due to the lens I am using) and we have a choice to select  one of the others, lets try to set the aperture to F11.
+\\
+\\
+We can set the aperture using either the absolute value (11) or the index next to the value (choice 5). Here is an example setting using the absolute value.
+\\
+<file>
+gphoto2 --set-config-value /main/capturesettings/aperture=11
+</file>
+If we check the aperture setting now, using the same command as before:
+\\
+<file>
+gphoto2 --get-config /main/capturesettings/aperture
+Label: Aperture
+Type: RADIO
+Current: 11
+Choice: 0 4.5
+Choice: 1 5.6
+Choice: 2 6.7
+Choice: 3 8
+Choice: 4 9.5
+Choice: 5 11
+Choice: 6 13
+Choice: 7 16
+Choice: 8 19
+Choice: 9 22
+</file>
+We can see now that the <color #ed1c24>Current: 11</color> means that we have set the aperture to F11.
