For news photographers covering accidents, natural disasters, war and conflict is all part of the job. In some parts of the world sudden death is an everyday event.
How we photograph scenes of death and injury is a tough call. We have to make decisions about how close we can get to the victims. If we are not working then perhaps we are just in the way and may even be making matters worse. At what stage do we stop shooting pictures to help somebody who is hurt? What if it is a colleague?
It is a balancing act and anyone who has ever covered a funeral will recognise that tangible point beyond which the presence of cameras becomes intrusive and hurtful for the bereaved.
