I rarely link to photographers who work for National Geographic or similar magazines or who do comparable work. This doesn't mean that their photography isn't nice - it's just that that kind of photography is just outside of my own area of interest. For those who'd like to see the portfolio of one of those photographers visit Sarah Leen's website.
(thanks, Tobias!)
PS: It might be just me but I think that National Geographic special edition about "swimsuits" (aka girls who are almost naked) is a travesty.
