Blogging
I was a very good amateur photographer, by that I mean I did what the stereotype would do, I joined and then ran a camera club, I did model nights, I knew all about the latest kit and would bore people with my photos of very boring things. As an amateur I would shoot or work on photos about a 100 days a year, and would only shoot what I liked.
Then along came the idea to do a daily photo blog. What happen next was not planned, but in a little over 2 years my hobby became my full time employment and blogging was the reason.
