My father was a part time wedding photographer who spent a lot of his spare time in the evening just looking at his cameras and cleaning them (or so it seems). I got interested but wasn't allowed to touch them. One of my early memories is of my mother showing me the reversed image in the viewfinder of a Rolleiflex (whilst my father was out!).
When I was ten years old, I was given an Agfa Isolette. My first task was to photograph my aunt's wedding, which I did, produced a perfectly exposed set of twelve prints, all cutting off the subjects' heads!
