A while back I was looking for photographers who were doing urban winter photography and I came across the work of Spanish photographer Luis Belmonte Díaz.
It was Zima (Winter), his work from Poland (I think he is based in Warsaw?) that caught my eye - I really like the way he has managed to capture this kind of long winter around the city.
But there are several other sets of work on his site (love the minimal front page...), such as Gdansk which are also well worth looking at.
He also has a low-key blog - sort of "Field Notes" of his day to day photography.
