Photography is a rewarding "hobby" both for the amateur and for the professional who can carve out time for personal work.
One of my favorite genres is self-portraiture, often with a mirror. This image has the added feature of shooting through a window, so that even though I was outside, it appears that I am in the interior being photographed from outside.
A little tip: You can see that I am holding a lens shade in the pinky of my right hand (ordinarily sort of like riding a bicycle with your helmet strapped to the handlebars or wearing a face mask around your neck). When shooting through glass, however, it is usually desirable to avoid reflections in the glass, so I remove the lens hood and press the lens directly against the glass.
