“The bright colours and unique designs really caught my eye,” says Sandra Herber of the ice-fishing huts on Lake Winnipeg in Manitoba, Canada, which she began shooting in 2018 for a series now nominated for a Sony world photography award. The shacks protect their occupants from the weather and allow access to the ice below for fishing. “I’ve been inside a couple of them,” says Herber, who was born in South Africa but now lives in Toronto, Canada, working as a librarian and taking photos in her spare time. “People regularly open the door and ask if I need to come inside the hut to warm up. Not many people wander around on the ice; I guess I was a bit of a curiosity.”
