Kitano, I've not sold anything but I was hired by a foreigner to take some shots of her and her boyfriend while he was visiting her.
Although she was happy, I didn't enjoy that at all. I really don't take portraits and didn't like the photos I took. As a hobby I can shoot what I want, but as a job it sucked.
Of course it would be nice to sell something but I'm new to photography and really don't know what I'm doing. Just enjoy doing it as a hobby.
It's a pretty good hobby for expats I think, something that gets you out and about without needing other people and a bottle.
