Woolland Woods, Dorset. Landscape photographer of the year 2020. “Taken in spring of 2018 in a wooded area close to Milborne St Andrew in Dorset, this was the third visit to the area in a matter of days. On the previous days, both devoid of morning mists, the light had been harsh and unappealing but the third day delivered stunning conditions with mist swirling through the trees. The low shooting position allowed more emphasis to be placed on the wild garlic and pathway”. (Photo by Chris Frost/UK Landscape Photographer of the Year 2020)
