Kacper Kowalski takes to the skies above Poland to gain a vantage point over a country gripped by harsh winter. Temperatures can drop to - 30 C degrees and stay below zero for months. The few specks of colour in these images - a yellow bus on an empty country road, a red tractor in a forest clearing - are the only signs of human activity in this monochrome landscape. The tracks left by vehicles on roads, fields and industrial estates trace geometric shapes into the unbroken snow cover and fine slivers track the movements of ships through frozen waterways. This set of images complements another series on autumn - click HERE to view the autumn images.
