You can launch gphoto2 from the command line, just enter
\\
gphoto2

Now because you didn't specify any parameters, gphoto2 will show you a list of available commands.

The first thing we need to do with gphoto2 is to check that we can detect the make and model of our camera, if this part fails, then it is likely that your camera is not supported. If you have a particularly old DSLR (acutally, gphoto2 works with cameras other than DSLRs) then you might not get any support, or only limited support.
\\
\\
So for instance, my 12 ish year old Canon 300D is supported (yay) and here is what is supported:
\\
Canon EOS 300D (normal mode) Image Capture, Liveview, Configuration
Canon EOS 300D (PTP mode)
\\
On the other hand, I would expect that any body I, or anyone else buys this year, will have to wait for some support to be added.

There is a list of supported models available at this url: http://gphoto.org/proj/libgphoto2/support.php
