<p>Jimmy Nelson spent time with several tribes around the world and photographed them "Before they Passed Away."<br> His photos have been re-posted everywhere. http://www.boredpanda.org/vanishing-tribes-before-they-pass-away-jimmy-nelson/<br> In photos ( http://www.beforethey.com/media/images/_DSC7021_website.jpg ) he is carrying a canon and a large format camera. What film do you think he is probably using to get such deep tones? </p>
