Here's a link to some recent photos in the Arctic by Sebastiao Salgado:

And some info from Canon re: his present equipment:

Interesting that he used to shoot medium format, but went di*ital in 2008 (see page three of the Canon article). Doesn't view images on a computer, but has "proof sheets" printed and eventually a true physical negative created from the digital file and a silver print made. What a great printer he has at Dupon in Paris.
