I just watched this powerful documentary last night on the photographer Tim Hetherington. I think it illustrates the dangers encountered in this hyper news/ documentary world where getting the shot in all too many cases is paid for by the life of the photographer.
The movie is available on HBO on demand. On a side note please notice all the film cameras Tim Hetherington worked with from a Rollei TLR to a Hasselblad.
