I have been a keen photographer since I was bought a self-build 110mm (remember those!) camera. in 1980!
In 2003 when my daughter arrived, we took her to a studio, remortgaged the house to pay for it, and wondered just how hard it could be. It turned out to be harder than I thought, but I soon had a studio and a wedding photography business.
I live in York, where you see a lot of people with expensive cameras set on Auto. That made me think, there must be a market for someone to explain how camera settings work, and how to capture scenes in the way they imagined. That was 11 years ago!
