Ursula Sprecher and Andi Cortellini are obsessed with people’s hobbies. The two Swiss artists have spent the past seven years traveling across their native Switzerland photographing gatherings of like-minded people in a myriad array of interests and niche groups.

Commended. In late May, about a quarter of a million snow geese arrive from North America to nest on Wrangel Island, in northeastern Russia. They form the world's largest breeding colony of snow geese. Photographer Sergey Gorshkov spent two months on the remote island photographing the unfolding dramas. Arctic foxes take advantage of the abundance of eggs, caching surplus eggs for leaner times. But a goose (here the gander) is easily a match for a fox, which must rely on speed and guile to steal eggs. “The battles were fairly equal”, notes Sergey, “and I only saw a fox succeed in grabbing an egg on a couple of occasions, despite many attempts”. Surprisingly, “the geese lacked any sense of community spirit”, he adds, “and never reacted when a fox harassed a neighboring pair nesting close by”.

Marco and Paolo have different backgrounds of experience: Paolo started as an illustrator then a photographer, and now he’s at Marco’s side and in his head throughout shooting. In turn, Paolo does all the post-production with Marco in his head and at his side. Marco has always worked as photographer”. – Tim Mitchell
