I had the pleasure of seeing a print of Richard Mosse's the other day at the Kemper Museum of Contemporary Art in Kansas City, MO.
The print was from his "Infraseries" (Men of Good Fortune) and measured about 6 feet wide I'd guess and shot on Aerochrome film. I strongly suspect that he might be getting his stock from Dean Bennici, mentioned above. (just a hunch).
Anyways, it was nothing short of breathtaking.
There's a lot more on his website that you should find quite impacting I suspect.
