This was taken on Kodak Tri-X film…
You know, the stuff that most people think is dead, but is actually used by professional photographers all over the place.
Check out Sebastio Salgado’s work here http://blog.ted.com/2013/05/01/sebastiao-salgado-a-gallery-of-spectacular-photographs/ for an example of an amazing photographer that still shoots film.
Tri-X has 13.5 stops of dynamic range, aka sensitivity to light, vs your average digital camera that has about 9-10 stops of dynamic range and you can understand why film is more sensitive to subtle changes in light. Kodak Tmax 400 has 19.5 stops of dynamic range. This kind of stuff makes the difference.
