I stumbled upon a really nice set of photos in Michael Yamashita’s “Daisetsuzan” in the August 2008 issue of National Geographic (pp. 92-108).
I read here that he prefers Fuji Velvia (although this source is dated, so I don’t know if it’s still true). I don’t know if this article was shot on film or not, but the feel of the photos is so gorgeous that I want to believe it’s true. If it’s digital, I want to know what sensor it is so I can buy a similar camera asap.
