I've been looking at the BBC's "Day in Pictures", and it got me thinking - what's your favourite photo?
Could be a documentary photo, something iconic from the news, or maybe it's a personal photo of you or friends.
A lot of James Nachtwey's work is very moving, but I'd be hard pushed to state that any of his are my favourites. It's a similar case with the burning monk, and the napalm girl. Hard hitting photos, but are they favourites?
