I'm curious about Sebastiao Salgado's images, or more specifically, his prints. They have an extremely long range of extremely smooth tonal gradations. Even more impressive is the fact that there is detail absolutely everywhere and all of the tones, from the most extreme shadow to brightest sky, show good contrast on the print despite the limited luminance range of photographic paper.
How is this done? I have never achieved anything remotely approaching this look with Tri-X for either 35mm or 120, even with pulling development. Is it extensive dodging and burning? If so, how does such a heavily dodged and burned photograph not show artifacts of the process (light/dark halos around dodged/burned objects, etc.)?
