Stunning.
Guy Sargent: What Lies Beneath the Surface
A gallery of nice "large-format landscape and architectural work" photos by Guy Sargent.
Michael Kenna Photographs
Beautiful photographs, at once empty and full. This set is called "Silent World" by whoever put this page together, but I can't find any reference to that collection on Kenna's website, so I think this is a fan mashup.
