Salgado was one of the photographers that made prints available to us for free when I did work for Doctors Without Borders. It was a fair exchange because some of the images he wanted were at MSF clinics and hospitals.
I always enjoyed working with him. I can't comment on the two movies Les saw since I didn't see them, or what the other Magnum shooters think.
I thought his prints were nice and always liked to use his work in MSF publications.
