I just watched a really moving documentary on BBC2 about a photo journalist David Gillanders.
I love to skip about with my camera capturing colour and pattern and sweet stuff, but he has the courage and skill to deal with the harsher realities of life. I was really moved by the coverage of his visits to the Ukraine to document the lives of the street kids there, moving and heartbreaking.
Sorry not to post a sample of his work but the contact button on his site is disabled just now so I can't get in touch for permission. Maybe later.
