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.

gphoto2 --list-config

Here is the listing that I get from my Canon EOS 700D.

/main/actions/uilock
/main/actions/syncdatetime
/main/actions/autofocusdrive
/main/actions/manualfocusdrive
/main/actions/eoszoom
/main/actions/eoszoomposition
/main/actions/eosviewfinder
/main/actions/eosremoterelease
/main/settings/datetime
/main/settings/reviewtime

/main/settings/movierecordtarget
/main/settings/ownername

/main/other/d402

So for example, in this list we can see a setting entitled /main/capturesettings/aperture which indicates we can control the aperture on this DSLR.

To see what the possible values for /main/capturesettings/aperture that gphoto2 supports, we can use the following syntax.

gphoto2 --get-config /main/capturesettings/aperture
