Description
The Biei Blue Pond’s turquoise colour is caused by naturally occurring aluminium hydroxide particles suspended in spring water that flows from the volcanic Tokachi-dake mountain — a natural colloidal suspension that scatters blue wavelengths. In winter, the pond surface freezes while retaining the colour beneath, creating an ice surface with the blue-green tint visible through the clear ice in shallow areas. The submerged dead birch trunks — trees that died when the pond was created by flood control construction — stand as sculptural bare forms in the winter landscape, their branches dusted by the light snow of the January photograph. Shot at f/11 on a 24-70mm zoom, the cold flat winter light creates even illumination without harsh shadows on the white snow and ice surface, communicating the quiet stillness of the Hokkaido winter landscape.
