My Nortons didn't give any warning. As for the photos, I thought they were OK. I'd like to go to a place like that and try some shooting, but I don't have a Canon camera.
I just watched the film. I've been a McCullin fan ever since I bought his book, "Hearts of Darkness" several decades ago. He's a very thoughtful man, and this shows in both his approach and his photos. I was happy to see that after taking photos of the poor he did had them a little money, which I think is only fair. Otherwise you are taking from a poor person and not giving anything back--it's not an even exchange. I don't often have the chance to do "street" photography, but when I am in a distant city I do give a couple of dollars to those who cooperate. It's the moral thing to do.
I can't see myself wandering around such a poor area with two expensive cameras though. I generally only take something small, such as my Leica IIIc or a Nikojn D5300 with small lenses. I mostly shoot b&w doing this, but India looks like it has to be shot in color. India is on my "list" of place I'd like to visit someday, but I think I would hire a local man to help keep me out of trouble. Don was wandering around with a platoon of people, but I would be more comfortable with just one. I don't like attracting attention.
